Before you buy one, it's important to understand [the difference between polyester and polypropylene rugs](https://www.blikai.com/blog/components-parts/polyester-vs-polypropylene-capacitors-explained).
These two types of rugs are made from different materials. Polyester is made from synthetic fabrics, while polypropylene is made from natural fibers.
Polyester rugs are cheaper than polypropylene rugs, but they are not as durable. Polypropylene is more expensive, but it's also more durable.
Polyester is the more popular choice for a rug because it is a synthetic fiber, meaning it is made from a series of connected molecules that are not derived from plants. Polyester rugs are often cheaper than rugs made from natural fibers, and they last longer due to their synthetic properties.
One downside to polyester rugs is that they can be difficult to clean. Polypropylene rugs, on the other hand, are made from a petroleum-based polymer that is less likely to cause allergies than polyester. They also tend to be more expensive than polyester rugs, but they are easy to clean and last longer. Ultimately, it is important to decide what type of rug is best suited for your needs.

[GROWI](https://growi.org/ja/), an open source wiki, can be easily installed and used by individuals. It is useful for using it as a substitute for everyday memos or for compiling information to be shared with family members.
As an easy way to operate such GROWI, we built it on a Raspberry Pi 5. I also used [Cloudflare Tunnel](https://www.cloudflare.com/ja-jp/products/tunnel/) to make it accessible from the Internet, so I will write down the contents.
## Notes.
Cloudflare Tunnel requires a domain managed by Cloudflare. If you don't mind changing the URL each time, you don't need a domain.
## Setting up Raspberry Pi 5
The Raspberry Pi Imager is used to install the Raspberry Pi OS. Note that Ubuntu Server 24.04 LTS (64bit) is selected as the OS, not Raspberry Pi OS.
## Installing Docker
The Docker installation procedure follows [Install Docker Engine on Ubuntu | Docker Docs](https://docs.docker.com/engine/install/ubuntu/).
```bash
# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc
# Add the repository to Apt sources:
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
$(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y
```
At the time of writing, 27.0.3 was installed; for the Raspberry Pi OS, this version appears to be out of date.
```bash
$ docker --version
Docker version 27.0.3, build 7d4bcd8
```
## Clone GROWI
The GROWI to use is obtained by Git cloning.
```bash
git clone https://github.com/weseek/growi-docker-compose.git growi
cd growi
```
## Build GROWI
Since we can't build GROWI as is because of the different architecture, modify the ``Dockerfile``.
```Dockerfile
# syntax = docker/dockerfile:1.4
# fix version
ARG version=7.0
FROM debian:stable-slim as fetch-dockerize
# fix dockerize version
ENV DOCKERIZE_VERSION v0.7.0
# Change dockerize URL for ARM64
RUN apt-get update && apt-get install -y curl \
&& curl -sL https://github.com/jwilder/dockerize/releases/download/$DOCKERIZE_VERSION/dockerize-linux-arm64-$DOCKERIZE_VERSION.tar.gz \x}}
| tar -xz -C /usr/local/bin
FROM weseek/growi:${version}
LABEL maintainer Yuki Takei <yuki@weseek.co.jp>
COPY --from=fetch-dockerize --link /usr/local/bin/dockerize /usr/local/bin/dockerize
```
And then build.
Then, build. Don't forget to specify the platform.
```bash
sudo docker build -t growi:7.0 --platform linux/arm64 .
```
## Fixing docker-compose
Then modify `docker-compose.yml`.
```yaml
version: '3'
services:
app:
image: growi:7.0 # fix to image instead of build
ports:
- 3000:3000 # Fix to allow external access
```
Now you can run `docker-compose up -d` to start GROWI. It will take a while for the startup to complete, so be patient. Once it is up, operation from a browser is smooth.
## Setting up Cloudflare Tunnel
We will use Cloudflare Tunnel so that we can access the site from the Internet as well.
```bash
wget https://github.com/cloudflare/cloudflared/releases/latest/download/cloudflared-linux-arm64.deb
sudo dpkg -i cloudflared-linux-arm64.deb
```
Next, log in using your Cloudflare account. During authentication, specify the domain you wish to use. The domain must be set up in advance with Cloudflare.
```bash
cloudflared login
```
Once authenticated, create a Tunnel. The configuration will be stored in `~/.cloudflared/{id}.json`. ``raspberry`` is an arbitrary name.
```bash
cloudflared tunnel create raspberry
```
At this point, the configuration is done for the subdomain. For example, `raspberry.example.com`.
### Create configuration file.
Create `~/.cloudflared/config.yaml`. Replace `${name}`, `${user}`, and `${id}` with the Tunnel name, user name, and ID, respectively.
```yaml
tunnel: ${name}
credentials-file: /home/${user}/.cloudflared/${id}.json
ingress: ${name}
- hostname: raspberry.example.com
service: http://127.0.0.1:3000
- service: http_status:404
```
Now start Tunnel and see if you can access it from the appropriate domain.
```bash
cloudflared tunnel run raspberry
```
### Servicing
As it is, we have to maintain SSH connection while Tunnel is running. So, we need to make Tunnel a service.
Create `/etc/systemd/system/cloudflared.service`.
```bash
sudo cloudflared --config /home/${user}/.cloudflared/config.yml service install
```
You will probably have it up and running as a service when you are done. The configuration file is copied to `/etc/cloudflared/config.yml` as follows.
```bash
$ systemctl status cloudflared
cloudflared.service - cloudflared
Loaded: loaded (/etc/systemd/system/cloudflared.service; enabled; preset: enabled)
Active: active (running) since Wed 2024-07-10 09:26:48 JST; 2h 7min ago
Main PID: 66342 (cloudflared)
Tasks: 11 (limit: 9074)
Memory: 16.4M (peak: 19.7M)
CPU: 15.731s
CGroup: /system.slice/cloudflared.service
└─66342 /usr/bin/cloudflared --no-autoupdate --config /etc/cloudflared/config.yml tunnel run
```
## Configure GROWI
GROWI requires URL configuration, so please set the URL that is accessed externally in the admin panel.
## Summary
Using Raspberry Pi 5 and Cloudflare Tunnel, we have shown how GROWI can be accessed from the Internet while operating GROWI at home, and it is easy and convenient to use HTTPS access with Cloudflare Tunnel!

1,917,990 | SSH Security Risks: Which Are the Most Common? | Overview of SSH Secure Shell (SSH) is one of the most ubiquitous protocols used today for... | 0 | 2024-07-10T03:05:24 | https://dev.to/me_priya/ssh-security-risks-which-are-the-most-common-d73 | devops, webdev, beginners, security | ## Overview of SSH
Secure Shell (SSH) is one of the most ubiquitous protocols used today for secure remote access, administration, and file transfers. It allows managing servers remotely over an encrypted connection. However, poor SSH security practices can inadvertently open doors for attackers.
While SSH itself is considered secure when properly implemented, misconfigurations and risky practices often lead to preventable breaches. According to studies, nearly half of all SSH servers on the internet allow password authentication, exposing them to brute force attacks.
In this article, we will overview some of the most common SSH security risks and how to address them through proper key management, access controls, updated SSH software, and other best practices. Adopting these measures can significantly reduce your SSH attack surface.
## Common SSH Security Risks
**Weak or Reused SSH Passwords**
The most prevalent SSH security risk is the use of weak, default, or reused passwords for SSH authentication. SSH can allow password-based login, meaning attackers can brute force or guess weak passwords to gain access.
Strong, unique passwords are a must for SSH. However, password-based SSH authentication should be avoided entirely if possible in favor of SSH key-based authentication, as discussed below.
**Outdated SSH Software**
Like any software, older versions of SSH server and client implementations can harbor vulnerabilities that get patched over time. Using the latest supported version of OpenSSH or whichever SSH software you rely on is an important step.
Outdated SSH software with unpatched security holes can give attackers an opening to bypass authentication or execute remote commands. It's also important to keep system-level packages like OpenSSL updated that support SSH cryptography.
**Allowing Password-Based SSH Authentication**
Enabling password-based SSH login, instead of requiring public key authentication, leaves SSH much more vulnerable to brute force password guessing attacks. Limiting SSH to key-based auth prevents these types of credential attacks against SSH.
Servers that allow SSH password authentication are trivial for attackers to identify with tools like Shodan and target. Most organizations do not have a justifiable reason to permit password-based SSH access when other options like keys exist.
**No Second Factor Authentication**
For higher-security environments, relying solely on SSH keys for authentication still leaves a gap if a private key is compromised.
Adding a second authentication factor (2FA) through time-based one-time passwords (TOTP) apps or hardware tokens provides an important additional layer of protection. TOTP 2FA forces attackers to have both the SSH key and a dynamically generated code.
**Unrestricted SSH Access**
Overly permissive SSH access is another common mistake. Rather than restricting which users can SSH to which servers, some organizations enable unfiltered SSH access from anywhere.
Proper SSH access controls limit which source IP addresses, users, ports, and protocols can be used to connect over SSH. Unlimited SSH connectivity to critical servers invites lateral movement.
**Poor SSH Key Management**
Poor practices around SSH key generation, distribution, and rotation are also problematic. Weak SSH keys, reused keys, lack of key rotation, and improper storage of private keys all undermine SSH security.
Following [SSH best practices](https://sslinsights.com/ssh-security-best-practices/) for creating strong keys, rotating them regularly, securing private keys properly, and managing key distribution through a reputable system is important.
**Use of Root Login**
Enabling root login over SSH should be avoided except for specific use cases. Attackers will always target the highest privileges first when looking to move laterally on a breach.
Disallowing direct root login forces adversaries to first compromise a standard user account, then attempt privilege escalation, raising the barrier to full server control.
## How to Reduce SSH Security Risks
Fortunately, there are specific measures administrators can take to lock down SSH security:
**Mandate SSH Key Authentication**
- Disable password-based SSH authentication methods like PasswordAuthentication
- Only permit public key authentication instead
- Require all personnel generate SSH key pairs to connect
**Enable Two-Factor Authentication**
- For SSH servers, integrate TOTP-based 2FA using Google Authenticator or hardware tokens
- Require both SSH private keys and a rotating token code to login
**Restrict Access Controls**
- Only allow SSH connectivity from dedicated jump boxes or bastions
- Limit source IP addresses able to establish SSH connections
- Configure user-based and group-based allow/deny access rules
**Update SSH Software Regularly**
- Run the latest supported versions of OpenSSH server and client software
- Patch and update associated libraries like OpenSSL that support SSH cryptography
**Automate SSH Key Management**
- Centralize storage and distribution of SSH keys through a secrets vault
- Automatically rotate SSH keys every 90 days or less
- Revoke SSH keys immediately if employees are off-boarded
**Monitor and Log SSH Activities**
- Send SSH logs to a security information event manager (SIEM)
- Alert on suspicious patterns like failed login attempts or unknown users
**Disallow Root SSH Logins**
- Prevent direct SSH access to root accounts except when absolutely required
- Force use of sudo privileges escalation model for more control
## Summary
Poor SSH security practices continue to cause many preventable data breaches every year. Applying measures like updated software, key-based authentication, restricted access, key management, and 2FA adoption can help lock down this ubiquitous remote access protocol.
While SSH remains highly secure when configured properly, organizations cannot overlook the risks introduced through weak credentials, permissive access, outdated software, and key vulnerabilities. Following best practices and monitoring SSH server logs allows capitalizing on SSH security while limiting exposure to common attacks.
## FAQs
**Is SSH secure by default?**
SSH itself is considered secure when configured properly. However, poor SSH key management, weak credentials, outdated software, and excessive access often undermine SSH security in practice. Following SSH best practices is required to realize its full security benefits.
**Should SSH password authentication be allowed?**
No, SSH password authentication should be prohibited in favor of SSH public key authentication. SSH key pairs provide much stronger security than passwords which are vulnerable to brute force attacks. Completely disabling the PasswordAuthentication option is recommended.
**What is the most common SSH vulnerability?**
The most common and easily preventable SSH vulnerability is allowing password-based SSH authentication. Servers permitting password-based auth invite brute forcing attacks. Enforcing key-based authentication blocks this common attack vector.
**Does SSH provide encryption?**
Yes, SSH provides strong symmetric encryption to encrypt the communication channel between SSH client and server. This protects passwords/keys and other data in transit from eavesdropping. Proper SSH configuration ensures all traffic is encrypted.
**Should root SSH login be allowed?**
Direct root logins via SSH should be disabled as a best practice. Users should first authenticate with their own SSH key, then escalate to root using sudo if needed. This raises the bar for attackers attempting to takeover root access on a server.
**How often should SSH keys be rotated?**
Industry best practice is to rotate SSH keys approximately every 90 days. More frequent rotation further limits exposure if a key is compromised. Old and unused SSH keys should be deleted when no longer needed.
**What is the most secure SSH encryption algorithm?**
The current recommended [encryption algorithms](https://dev.to/me_priya/why-every-website-needs-an-ssl-encryption-4bcb) for SSH are AES-256 or AES-128 for symmetric encryption, SHA-2 for data integrity, and ECDH/[ECDSA](https://sslinsights.com/what-is-ecdsa-encryption-how-it-works/) using curve P-256/384 for asymmetric encryption.

# Spring Boot, React, and the Quest for SEO Supremacy
In today's digital landscape, a visually appealing and functional web application is only half the battle won. The other half, often more challenging, is ensuring your creation reaches its intended audience. This is where Search Engine Optimization (SEO) steps in, acting as the bridge connecting your application with eager users. While traditional server-side rendering (SSR) inherently caters to SEO needs, the rise of JavaScript frameworks like React, often coupled with RESTful backends like Spring Boot, presents unique challenges.
This post delves into the intricacies of optimizing full-stack applications built with Spring Boot and React for SEO. We'll explore common use cases and demonstrate how to leverage React's Server-Side Rendering (SSR) capabilities to conquer the SEO battleground. Additionally, we'll examine alternatives from prominent cloud providers and analyze their strengths.
### Understanding the SEO Challenge
Search engines rely heavily on web crawlers to index and rank websites. These crawlers excel at parsing static HTML content but often struggle with dynamic content generated by JavaScript frameworks like React. When a crawler encounters a React application, it typically sees an initial HTML skeleton with JavaScript code responsible for fetching data and rendering the actual content. If the crawler doesn't execute this JavaScript, it misses crucial content, resulting in poor SEO performance.
### Server-Side Rendering (SSR) to the Rescue
SSR provides an elegant solution to this predicament. Instead of sending a barebones HTML file to the client, the server pre-renders the React components into fully formed HTML on each request. This HTML, replete with all the necessary data, is then served to the crawler, ensuring complete content indexing and optimal SEO performance.
### Use Cases: Unlocking the Power of SSR
Let's explore some compelling use cases where SSR proves invaluable:
**1. E-commerce Platforms:**
For e-commerce websites built with Spring Boot and React, product pages are paramount. Each product page needs to be crawlable and indexable by search engines to attract organic traffic. SSR ensures that product details, images, and reviews are all rendered server-side, making them readily accessible to search engine crawlers.
**2. Content-Heavy Websites:**
Websites and applications rich in dynamic content, such as blogs, news portals, and online magazines, benefit significantly from SSR. By rendering articles, author information, and comments on the server, these platforms ensure search engines can properly index their content, boosting their search ranking potential.
**3. Social Media Platforms:**
Social media platforms thrive on user-generated content. SSR can be used to render user profiles, posts, and interactions server-side, ensuring this dynamic content gets indexed and contributes to the platform's overall SEO performance.
**4. Single Page Applications (SPAs) with Dynamic Routing:**
While SPAs offer seamless user experiences, their reliance on client-side rendering can hamper SEO. SSR addresses this by pre-rendering different routes on the server, ensuring each page of the SPA is crawlable and indexable.
**5. Enterprise Websites with Complex Data Structures:**
Large enterprise websites often manage vast amounts of data, dynamically rendering it based on user interactions. SSR enables these websites to serve SEO-friendly, data-rich pages, improving their visibility to search engines.
### Alternatives on the Horizon
While Spring Boot with React SSR provides a robust solution, other cloud providers offer their own approaches to enhance SEO in JavaScript-driven applications:
- **AWS Amplify:** Simplifies building and deploying full-stack applications with serverless backends and supports SSR out of the box.
- **Netlify:** Provides static site generation (SSG) and SSR capabilities, making it easy to build and deploy performant and SEO-friendly web applications.
- **Vercel:** Similar to Netlify, Vercel offers a developer-friendly platform with a focus on SSG and SSR for optimal SEO.
Each of these platforms has its strengths and caters to specific use cases. The choice ultimately depends on the specific requirements and existing infrastructure of your project.
### Conclusion
In the ever-evolving world of web development, staying ahead of the SEO curve is crucial for success. While JavaScript frameworks like React offer unparalleled flexibility and user experience, their reliance on client-side rendering can pose challenges for SEO. By embracing Server-Side Rendering (SSR), we empower our Spring Boot and React applications to conquer these challenges, ensuring our creations reach their full potential in the vast digital landscape.
## Advanced Use Case: Building a Scalable News Portal
Imagine building a high-traffic news portal that aggregates content from various sources and delivers a personalized experience to millions of users. This platform needs to be:
- **SEO Optimized:** Each news article needs to be instantly crawlable and indexable.
- **Highly Scalable:** The architecture must handle sudden spikes in traffic, especially during breaking news events.
- **Performant:** Users expect lightning-fast loading times, regardless of the volume of content or traffic.
**Here's a potential solution leveraging the power of AWS:**
1. **Content Ingestion and Processing:**
- Utilize AWS Lambda functions triggered by an SQS queue to fetch news articles from various RSS feeds and APIs.
- Employ AWS Lambda functions with NLP services like Amazon Comprehend to extract keywords, entities, and sentiment from articles for personalization and SEO optimization.
- Store processed articles and metadata in a highly scalable NoSQL database like Amazon DynamoDB.
2. **Server-Side Rendering and Caching:**
- Implement a serverless SSR architecture using AWS Lambda and Amazon CloudFront to dynamically render personalized news feeds for each user request.
- Utilize CloudFront's robust caching capabilities to cache rendered HTML for frequently accessed articles, reducing latency and server load.
3. **Search and Personalization:**
- Leverage Amazon Elasticsearch Service to power a robust search functionality, enabling users to easily find relevant articles.
- Employ Amazon Personalize to build personalized news recommendations based on user reading history, preferences, and real-time engagement data.
4. **Monitoring and Analytics:**
- Integrate Amazon CloudWatch for real-time monitoring of application performance, resource utilization, and user behavior.
- Utilize Amazon Athena to query and analyze vast amounts of log data to gain insights into user engagement and further optimize SEO strategies.
This example showcases how combining React SSR with a robust cloud infrastructure on AWS can create a highly scalable, performant, and SEO-optimized news portal capable of handling massive traffic and delivering personalized content to millions of users.

1,917,996 | 5 Tips for Using the Arrow Operator in JavaScript | JavaScript’s arrow functions, introduced in ECMAScript 6 (ES6), offer a concise syntax for writing... | 0 | 2024-07-10T03:06:18 | https://dev.to/devops_den/5-tips-for-using-the-arrow-operator-in-javascript-1ne2 | webdev, javascript, programming, tutorial | JavaScript’s arrow functions, introduced in ECMAScript 6 (ES6), offer a concise syntax for writing function expressions. The arrow operator (=>) has become a popular feature among developers for its simplicity and readability. However, mastering its nuances can help you write more efficient and cleaner code. Here are five tips for using the arrow operator in JavaScript.
## 1. Understand the Syntax
Arrow functions provide a more concise syntax compared to traditional function expressions. Here’s a quick comparison:
### Traditional Function:
```
var multiply = function(a, b) {
return a * b;
};
```
### Arrow Function:
```
let multiply = (a, b) => a * b;
```
The arrow function syntax removes the need for the function keyword, uses parentheses for parameters, and directly returns the expression after the arrow if it's a single statement. This can make your code cleaner and more readable.
## 2. Lexical this Binding
One of the key differences between traditional functions and arrow functions is the way they handle the this keyword. In traditional functions, this is determined by how the function is called. Arrow functions, on the other hand, don’t have their own this context; they inherit this from the parent scope at the time they are defined.
### Traditional Function:
```
function Timer() {
this.seconds = 0;
setInterval(function() {
this.seconds++;
}, 1000);
}
```
In this example, this.seconds will result in an error because this inside the setInterval function refers to the global context.
### Arrow Function:
```
function Timer() {
this.seconds = 0;
setInterval(() => {
this.seconds++;
}, 1000);
}
```
With the arrow function, this correctly refers to the Timer object, as it inherits this from the surrounding lexical scope.
## 3. Implicit Returns
Arrow functions allow for implicit returns, meaning if the function body consists of a single expression, it will be returned without needing the return keyword.
### Single Expression:
```
let add = (a, b) => a + b;
```
For multi-line function bodies, you must use curly braces and explicitly use the return statement.
### Multi-line Function:
```
let multiply = (a, b) => {
let result = a * b;
return result;
};
```
## 4. Arrow Functions with No Parameters or Multiple Parameters
When an arrow function has no parameters, you still need to include an empty set of parentheses.
### No Parameters:
```
let greet = () => console.log('Hello, World!');
```
For multiple parameters, simply list them inside the parentheses.
### Multiple Parameters:
## 5. Avoid Arrow Functions in Methods and Constructors
While arrow functions are handy, they are not suitable for all scenarios. Specifically, you should avoid using them as methods in objects or constructors because of their lexical `this` binding.
### Arrow Function in Object Method (Incorrect):
```
let person = {
name: 'John',
greet: () => {
console.log(`Hello, my name is ${this.name}`);
}
};
person.greet(); // Output: Hello, my name is undefined
```
Here, `this.name` is undefined because this does not refer to the `person` object.
### Traditional Function in Object Method (Correct):
```
let person = {
name: 'John',
greet: function() {
console.log(`Hello, my name is ${this.name}`);
}
};
person.greet(); // Output: Hello, my name is John
```
Additionally, arrow functions should not be used as constructors because they do not have their own `this` context and cannot be used with the new keyword.
## Conclusion
Arrow functions offer a sleek and modern way to write function expressions in JavaScript, but understanding their nuances is key to using them effectively. By mastering these five tips, you can harness the full power of arrow functions while avoiding common pitfalls. Use them wisely to write cleaner, more efficient, and more readable code.

1,917,997 | ACID: O Pilar dos Bancos de Dados Relacionais | O Que é ACID em Bancos de Dados Relacionais? Se você já trabalhou com bancos de dados... | 0 | 2024-07-10T15:05:00 | https://dev.to/marialuizaleitao/acid-o-pilar-dos-bancos-de-dados-relacionais-5g47 | datascience, sql, postgres, community | # O Que é ACID em Bancos de Dados Relacionais?
Se você já trabalhou com bancos de dados relacionais, provavelmente já se deparou com a sigla ACID. Mas o que exatamente isso significa e por que é tão importante? Vamos explorar cada componente de ACID e entender o seu papel nos sistemas de banco de dados.
### O que é ACID?
ACID é um acrônimo que representa quatro propriedades fundamentais garantidas pelos sistemas de banco de dados relacionais para garantir a integridade e a confiabilidade das transações. Estas propriedades são: Atomicidade, Consistência, Isolamento e Durabilidade.
### Componentes do ACID
#### Atomicidade (Atomicity):
- **Conceito:** Assegura que todas as operações dentro de uma transação são completadas com sucesso ou nenhuma delas é aplicada.
- **Exemplo real:** Em uma transação de transferência bancária, se a transferência do valor da Conta A para a Conta B falhar, nenhuma das contas deve ser alterada.
#### Consistência (Consistency):
- **Conceito:** Garante que uma transação leva o banco de dados de um estado válido para outro estado válido, preservando as regras de integridade.
- **Exemplo real:** Após uma transação, todas as regras de integridade, como restrições e gatilhos, são respeitadas. Se um depósito for feito, o saldo total do banco deve refletir essa mudança.
#### Isolamento (Isolation):
- **Conceito:** Assegura que as operações de uma transação são isoladas de outras transações simultâneas. As transações não devem interferir umas com as outras.
- **Exemplo real:** Se duas pessoas estão comprando o último item disponível em uma loja online ao mesmo tempo, o sistema deve garantir que apenas uma transação finalize a compra.
#### Durabilidade (Durability):
- **Conceito:** Garante que uma vez que uma transação foi concluída com sucesso, suas alterações são permanentes, mesmo em caso de falha do sistema.
- **Exemplo real:** Após a confirmação de um pedido em um e-commerce, os detalhes do pedido devem permanecer registrados, mesmo que ocorra uma queda de energia logo em seguida.
### Importância do ACID
- **Confiabilidade:** ACID é crucial para garantir que os bancos de dados se comportem de maneira previsível e confiável.
- **Integridade de Dados:** Mantém a integridade dos dados, assegurando que eles não fiquem em um estado incorreto.
- **Segurança:** Proporciona uma camada adicional de segurança, garantindo que as transações sejam corretamente registradas e mantidas.
### Conclusão
As propriedades ACID são muito importante nos bancos de dados relacionais, já que garantem que as transações serão realizadas de forma segura, confiável e eficiente. Compreender ACID é fundamental para qualquer profissional que trabalhe com bancos de dados, pois garante a integridade e a consistência dos dados, aspectos que são vitais em qualquer aplicação crítica.

# Introduction
This article provides steps for how to create an Azure-based hub virtual network (VNet) with subnets and address space from scratch, as well as how to configure a virtual network peering. This is to allow for the virtual networks to communicate with each other securely and privately.
# Scenario
A hypothetical Web Application requires network isolation and segmentation in a network for secure and private communication. The virtual networks and subnets will be created in the following steps.
## Step 1: Create hub and spoke virtual networks and subnets
### I. Creating the virtual networks
- Open a browser and navigate to the Azure portal and login.
- To create a Virtual Network, click the hamburger icon at the top left
hand side corner of the portal.
- In the displayed pane, select **Virtual Networks**.
- In the “Virtual Networks” portal pane, select **+ Create**.
- At the **Resource group label** select "create new" to create a new
resource group. Give the resource group a name and click **Ok**. Keep in
mind that this is the "parent directory" for the virtual networks to be
created.
- Also, give a name to the virtual network at the "virtual network name"
label.
- Select a Region from the dropdown list at the **Region** label. In this
case, I selected **East US**.
- Next, Select the **IP Addresses** tab at the top of the page.
### II. Create subnets for the first Virtual Network.
- At the dropdown menu displayed above the **address space** box on the
displayed page, check that the dropdown is set to **Add IPv4 address
space**
- In the address space box, change **Subnet address range** to **10.1.0.0/16** (This is usually the default IP address so you may not need to change it in this instance).
- locate a pen icon at the bottom corner, in the address space box (next
to the garbage can icon). Click on this icon to edit the default **Subnet** name.
- Change **Subnet** name to **frontend**
- Also, change **Subnet address range** to **10.1.0.0/24** using the
**size** label. Leave all other settings as their defaults.
- Click **Add** to close the **Edit Subnet** pane. This
completes the creation of the first Subnet.
- The next step is to create the second subnet. As you can see, the
**frontend** subnet is listed in the box. We need to create another
subnet in this virtual network. Again, locate the pen
icon at the bottom (next to the garbage can icon). Click on this icon to
add another **Subnet**.
- Also, change the **subnet** name to **backend**, then change the
**Subnet address range** to **10.1.0.0/24**.
- Again, leave all other settings as their defaults. Click **Add** to close the **edit subnet** pane.
- Select **Review + Create** to validate the configurations and **Create** to create the first virtual network.
### III. Creating the second virtual networks
- Creating the second virtual network is similar to creating the first
virtual network.
- click the hamburger icon at the top left-hand side corner of the Azure
portal.
- Again, in the displayed pane, select “Virtual Networks”.
- In the “Virtual Networks” portal pane, select “+ Create”.
- At the Resource group label select from the drop-down menu the first
Resource group that was created.
- Also, give a name to the virtual network at the "virtual network name"
label. Here the name I supplied was **Hub-vnet**.
- Select a similar Region from the dropdown like the first virtual network
list at the Region label. In the previous virtual network, I selected
**East US**.
- Next, Select the **IP Addresses** tab at the top of the page.
- set the **IPv4 address space** to **10.1.0.0/16**
### IV. Create a subnet for the second Virtual Network.
- In the address space box, locate a pen icon at the bottom (next to the
garbage can
icon).
- Click on this icon to edit the default **Subnet** name.
- At the flyout pane, change **subnet purpose** to **Azure Firewall** from
the **Default** settings.
- Change Subnet **name** label to **AzureFirewallSubnet**
- Also, change **Subnet address range** to **10.1.0.0/26**.
- Leave all other settings as their defaults.
- select the **save** button to Close the **edit Subnet** pane. This
completes the creation of the Subnet for the second virtual network.
- Select **Review + Create** to validate the settings.
- After validation is complete select the **Create** button to create the
second virtual network and watch the process complete deployment.
## Step 2: Setup a peer relationship between the virtual networks
- Once the deployment is complete for the second virtual network, navigate
back to the portal. In the search bar type **resource groups** and
select **Resource Groups** from the results.
- Select the required **Resource group** in the main pane and confirm that
both virtual networks have been deployed.
- Setting up a peer relationship between the two virtual networks aims to
allow traffic to flow in both directions between the **app-vnet** and
**hub-vnet** virtual networks.
- In the Portal and the resource group view, Select the first virtual
network created from the table. In my case it was the **app-vnet**
virtual network.
- On the **app-vnet** overview page select **settings** the left-hand
sidebar of the portal.
- Scroll down and select **peerings** to add peering.
- In the **app-vnet** peerings pane, Select **+ Add**.
- Fill out under the **Remote virtual network summary** heading supply a
name for **Peering link name** with **app-vnet-to-hub**.
.
- Select the first virtual network from the drop-down.
- Scroll the page down to the **Local virtual network summary** heading.
Fill out the **Peering link name** with **hub-to-app-vnet**.
- Leave all other settings as their defaults. Select **Add** to create the
virtual network peering.
- You should see a notification at the top right of the page that says
**Adding virtual network peering**
- Once the process completes, and after the configuration updates,
this validates that the Peering status is set to **Connected**.
(you may have to refresh the page to see the updated status)
# Conclusion.
This article explains how to provide network isolation and segmentation for a web application, in an Azure virtual network with subnets with address space. We have learned the following:
- Creating virtual networks
- Creating subnets within the virtual networks, and
- Configuring virtual networking peering which means allowing two or more
virtual networks to connect and appear as one for connectivity purposes.
It's been great sharing my journey into cloud engineering and I hope to see you soon on the other articles.

1,918,021 | Matplotlib Legend Toggling Tutorial | In this lab, we will learn how to enable picking on the legend to toggle the original line on and off using Python Matplotlib. | 27,678 | 2024-07-10T03:24:38 | https://dev.to/labex/matplotlib-legend-toggling-tutorial-4lj6 | python, coding, programming, tutorial |
## Introduction
This article covers the following tech skills:
In this lab, we will learn how to enable picking on the legend to toggle the original line on and off using Python Matplotlib.
### VM Tips
After [the VM](https://labex.io/tutorials/python-matplotlib-legend-toggling-tutorial-48802) startup is done, click the top left corner to switch to the **Notebook** tab to access Jupyter Notebook for practice.
Sometimes, you may need to wait a few seconds for Jupyter Notebook to finish loading. The validation of operations cannot be automated because of limitations in Jupyter Notebook.
If you face issues during learning, feel free to ask Labby. Provide feedback after the session, and we will promptly resolve the problem for you.
## Import Required Libraries
First, we need to import the required libraries, which are NumPy and Matplotlib.
```python
import matplotlib.pyplot as plt
import numpy as np
```
## Prepare Data
We will generate two sine waves with different frequencies using NumPy.
```python
t = np.linspace(0, 1)
y1 = 2 * np.sin(2*np.pi*t)
y2 = 4 * np.sin(2*np.pi*2*t)
```
## Create Figure and Axes
We will create a figure and axes using Matplotlib and set the title of the plot.
```python
fig, ax = plt.subplots()
ax.set_title('Click on legend line to toggle line on/off')
```
## Create Lines and Legend
We will create two lines and a legend using Matplotlib.
```python
line1, = ax.plot(t, y1, lw=2, label='1 Hz')
line2, = ax.plot(t, y2, lw=2, label='2 Hz')
leg = ax.legend(fancybox=True, shadow=True)
```
## Map Legend Lines to Original Lines
We will map the legend lines to the original lines using a dictionary.
```python
lines = [line1, line2]
lined = {} # Will map legend lines to original lines.
for legline, origline in zip(leg.get_lines(), lines):
legline.set_picker(True) # Enable picking on the legend line.
lined[legline] = origline
```
## Define the On Pick Event Function
We will define the on pick event function that will toggle the visibility of the original line corresponding to the legend proxy line.
```python
def on_pick(event):
# On the pick event, find the original line corresponding to the legend
# proxy line, and toggle its visibility.
legline = event.artist
origline = lined[legline]
visible = not origline.get_visible()
origline.set_visible(visible)
# Change the alpha on the line in the legend, so we can see what lines
# have been toggled.
legline.set_alpha(1.0 if visible else 0.2)
fig.canvas.draw()
```
## Connect the On Pick Event Function to the Canvas
We will connect the on pick event function to the canvas.
```python
fig.canvas.mpl_connect('pick_event', on_pick)

Isso ocorre em todas as áreas, principalmente na área de T.I.
Ao iniciar os estudos em programação, muitos de nós já queremos construir sistemas complexos, como os da Netflix ou da Uber, sozinhos, e em alguns meses já imaginamos ter milhões na conta e estar em alguma praia do Caribe.
Durante o boom da área, muitos cursos se aproveitaram dessa mentalidade, oferecendo promessas como "Construa sua pokedex e torne-se um profissional sênior em 6 meses". Muitas pessoas, por desconhecimento ou buscando atalhos, caíram no papo dos coaches.
Nesse período, muitas pessoas entraram no mercado. No entanto, hoje o cenário é diferente e as empresas buscam profissionais com experiência e uma base sólida para resolver problemas. Infelizmente, os coaches só ensinaram a copiar e colar sem nenhuma base.
### O que vamos aprender?
Vamos aprender lógica de programação, algoritmos e estruturas de dados, que são a base para se tornar um programador capaz de resolver problemas, pois é isso que um programador faz: resolve problemas. Você pode até achar isso chato, mas é essencial no dia a dia.
{% embed https://www.youtube.com/watch?v=PH26jtYoEwE %}
### Básico sobre o Python
O [Python](https://www.hostinger.com.br/tutoriais/python-o-que-e) é uma linguagem de programação criada antes mesmo do Java por Guido van Rossum. Ela é uma linguagem de alto nível, o que significa que é muito semelhante à linguagem humana. Veja o exemplo abaixo:
```py
print("Olá, sou um script em Python que imprime uma mensagem na tela")
```
Além de ser simples de aprender, é uma linguagem muito versátil, utilizada para análise de dados, scripts e back-end. Python também é usado por grandes e pequenas empresas como Google, Meta, OpenAI e muitas outras, possuindo uma comunidade bastante ativa com diversos recursos como ebooks, livros e discussões em fóruns.
### O que vamos precisar?
Precisaremos apenas de uma conta no [Google Colab](https://colab.research.google.com/), uma plataforma que nos permite executar códigos Python de maneira simples. Caso prefira, sinta-se à vontade para instalar o Python e o VSCode em seu PC e codar por ele.

Exercite sua lógica com o jogo dos Missionários e Canibais. Sua missão é atravessar os missionários e canibais para a outra margem do rio, mas tenha cuidado: quando o número de missionários for menor que o de canibais em um lado do rio, os missionários serão devorados.

Protecting personal information and data security has never been more crucial. Here are some practical cybersecurity tips to help safeguard your digital life:
**Use Strong Passwords**
Think of your password like the lock on your front door. A strong password should be complex, combining letters, numbers, and symbols. For example, avoid using passwords like "123456" or "password," as they are too easy to crack.
**Beware of Phishing Attacks**
Imagine receiving an email that appears to be from your bank, stating there's unusual activity on your account and prompting you to click a link to verify. Don't rush to click! It could be a phishing email crafted by scammers aiming to trick you into revealing personal information. Remember, a legitimate bank will never ask for your password or personal information via email.
**Keep Software Updated**
When your phone, computer, or other devices prompt you to update software, don't ignore it. These updates often patch known vulnerabilities and help prevent hackers from gaining access.
**Enable Two-Factor Authentication**
Just like needing two keys to open a bank safe deposit box, enabling two-factor authentication means besides your password, you'll need to input another form of verification, such as a text message code or app-generated token, to confirm your identity.
**Regularly Back Up Data**
Ever wondered what would happen if your computer fell victim to ransomware, encrypting all your files? Regularly back up important files to an external hard drive or cloud storage to mitigate such risks.
Cybersecurity isn't just the responsibility of IT professionals; it's everyone's responsibility. By following these simple steps, you can effectively protect your digital life.

There are several ways to do... | 0 | 2024-07-10T03:34:49 | https://dev.to/sudhanshu_developer/getting-data-through-using-api-in-javascript-43bl | javascript, webdev, beginners, programming | When building web applications, making HTTP requests is a common task. There are several ways to do this in JavaScript, each with its own advantages and use cases. In this post, we’ll explore four popular methods: `fetch(), axios(), $.ajax()`, and `XMLHttpRequest()`, with simple examples for each.
**1. Using fetch()**
The `fetch()` function allows you to request HTTP to fetch resources from a network. It uses promises, which makes it easier to handle asynchronous operations.
_Example_
```
fetch('https://api.example.com/data')
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error('Error:', error));
```
**2. Using Axios()**
`axios()` is a popular `HTTP` client for making requests from browsers or `Node.js `applications. It is similar to the built-in `fetch()` API but includes additional features such as request and response interceptors, automatic `JSON `parsing, and more.
_Example_
```
axios.get('https://api.example.com/data')
.then(response => console.log(response.data))
.catch(error => console.error('Error:', error));
```
**3. Using $.ajax()**
If you’re working with `jQuery`, you can use the `$.ajax()` function to make HTTP requests. It provides a simple interface for making AJAX requests and handling responses.
_Example_
```
$.ajax({
url: 'https://api.example.com/data',
method: 'GET',
success: function(data) {
console.log(data);
},
error: function(error) {
console.error('Error:', error);
}
});
```
**4. Using XMLHttpRequest()**
The `XMLHttpRequest` object provides an easy way to fetch data from a URL without a page refresh. It's a bit lower-level than `fetch()` or libraries like Axios, but it's still widely used in many applications.
_Example_
```
var xhr = new XMLHttpRequest();
xhr.open('GET', 'https://api.example.com/data', true);
xhr.onload = function() {
if (xhr.status >= 200 && xhr.status < 300) {
console.log(JSON.parse(xhr.responseText));
} else {
console.error('Error:', xhr.statusText);
}
};
xhr.onerror = function() {
console.error('Request failed');
};
xhr.send();
```
In this example, we create a new XMLHttpRequest, open a GET request, and handle the response by checking the status code and parsing the response text.

## How It Is Used
### Installation
```sh
npm install axios
```
### Basic Usage
```javascript
const axios = require('axios');
// Performing a GET request
axios.get('https://api.example.com/data')
.then(response => {
console.log(response.data);
})
.catch(error => {
console.error('Error fetching data:', error);
});
```
### Detailed Usage with Comments
```javascript
const axios = require('axios');
// Create an instance of axios with default settings
const instance = axios.create({
baseURL: 'https://api.example.com',
timeout: 1000,
headers: { 'X-Custom-Header': 'foobar' }
});
// Interceptor to log request details
instance.interceptors.request.use(request => {
console.log('Starting Request', request);
return request;
});
// Interceptor to log response details
instance.interceptors.response.use(response => {
console.log('Response:', response);
return response;
});
// Making a POST request
instance.post('/user', {
firstName: 'Fred',
lastName: 'Flintstone'
})
.then(response => {
console.log('User created:', response.data);
})
.catch(error => {
console.error('Error creating user:', error);
});
```
## Misuse Examples

```javascript
axios.get('https://api.example.com/data')
.then(response => {
console.log(response.data);
});
// Error handling should not be omitted
```

1,918,048 | The All-New display Property. | Starting with Chrome 115, there are multiple values for the CSS display property. display: flex... | 0 | 2024-07-10T04:22:58 | https://dev.to/manojgohel/the-all-new-display-property-3572 | css, html, webdev, javascript | Starting with Chrome 115, there are multiple values for the CSS `display` property. `display: flex` becomes `display: block flex` and `display: block` becomes `display: block flow`. The single values you know are now considered legacy but are kept in the Browsers for backward compatibility.
# Why is it long overdue?
In short: It changes how we can explain things such as the Box Model. The specification is still a CR Snapshot, meaning that the W3C collects experiences from the implementors to finalize the standard. Therefore, some of it might still change.
The rework splits the display type into two parts: The outer display type and the inner display type.
The outer display type dictates how the [principal box](https://www.w3.org/TR/css-display-3/%23principal-box) itself participates in [flow layout](https://www.w3.org/TR/css-display-3/%23flow-layout).
The inner display type dictates how its descendant boxes are laid out (except for replaced elements, that’s a bit more complex).
Therefore `display: flex` becomes `display: block flex` meaning the outer display type is block (it behaves as a block element on the outside), but its child elements are rendered according to the flex layout.
This is the same behavior as before, but with this change, we are able to talk about the influence of the display property regarding child elements and surrounding elements. In my opinion, this mental model makes it easier to create more predictable layouts, and it is simpler to explain the different layout modes and their effects.
In newer courses or tutorials, a good explanation of the Box Model needs to cover not only margins, borders, paddings, width, and height but also box-sizing and the display property.
# What are valid values of the display property?
As already mentioned, some old properties are now legacy. Here are all valid properties:
For the multiple-value syntax `display: outer-type inner-type` valid outer types are _block_, _inline_, and _run-in_. Valid inner display types are _flow_, _flow-root_, _table_, _flex_, _grid_, and _ruby_.
There are also valid single-values: _list-item_, _contents_, and _none_.
On top of that, CSS has some internal display values that remain valid. These values will be computed when using table or ruby display types.
The following combinations are now legacy: _inline-block_, _inline-table_, _inline-flex_, and _inline-grid_. They can be replaced with their multi-value equivalents, e.g.: `display: inline flex`.
Multi-Values are supported on recent versions of modern Browsers: [https://caniuse.com/mdn-css\_properties\_display\_multi-keyword\_values](https://caniuse.com/mdn-css_properties_display_multi-keyword_values)

1,918,050 | Design a High Availability System: Everything on Availability of System | Designing for High Availability High availability is a critical aspect of system design,... | 0 | 2024-07-10T04:27:56 | https://dev.to/zeeshanali0704/designing-for-high-availability-1o3 | systemdesign, systemdesignwithzeeshanali, learning, design | # Designing for High Availability
High availability is a critical aspect of system design, ensuring that a system remains operational and accessible to users, even in the face of failures. It is typically expressed as a percentage of uptime over a given period. For example, a system with 99.9% availability is expected to be operational 99.9% of the time, which translates to roughly 8.76 hours of downtime per year.
## What is Availability in System Design?
Availability in system design refers to the ability of a system to remain operational and accessible to users. It is a crucial aspect of system reliability, particularly for critical systems such as online banking, e-commerce websites, and cloud computing platforms. High availability prevents financial losses, reputational damage, and user dissatisfaction by ensuring users can access the system and its services whenever needed.
Achieving high availability involves designing systems with redundancy, fault tolerance, and the ability to quickly recover from failures. Redundancy involves duplicating critical components or functions of a system to increase reliability. For example, using multiple servers in a load-balanced configuration ensures that if one server fails, others can handle the load. Fault tolerance involves designing systems with built-in mechanisms to detect, isolate, and recover from faults. For example, using error detection and correction codes in communication protocols can help detect and correct errors in data transmission.
## How is Availability Measured?
Availability is measured as the percentage of a system’s uptime in a given time period, calculated as follows:
Availability = Uptime / (Downtime + Uptime)
### The Nine’s of Availability
Availability is often measured in terms of "nines" rather than percentages. Here’s a breakdown of different levels of availability and their corresponding downtime:
| Availability % | Downtime (Year) | Downtime (Month) | Downtime (Week) |
|----------------|------------------|------------------|-----------------|
| 90% (one nine) | 36.53 days | 72 hours | 16.8 hours |
| 99% (two nines) | 3.65 days | 7.20 hours | 1.68 hours |
| 99.9% (three nines) | 8.77 hours | 43.8 minutes | 10.1 minutes |
| 99.99% (four nines) | 52.6 minutes | 4.32 minutes | 1.01 minutes |
| 99.999% (five nines) | 5.25 minutes | 25.9 seconds | 6.05 seconds |
| 99.9999% (six nines) | 31.56 seconds | 2.59 seconds | 604.8 milliseconds |
| 99.99999% (seven nines) | 3.15 seconds | 263 milliseconds | 60.5 milliseconds |
| 99.999999% (eight nines) | 315.6 milliseconds | 26.3 milliseconds | 6 milliseconds |
| 99.9999999% (nine nines) | 31.6 milliseconds | 2.6 milliseconds | 0.6 milliseconds |
## Patterns to Achieve High Availability
### Redundancy
Employing redundancy involves duplicating components (e.g., servers or storage) to ensure that another can take over seamlessly if one fails. There are two types of redundancy:
- **Passive Redundancy**: In this pattern, an active node handles all the traffic while a passive (standby) node waits to take over in case the active node fails.
Some components are active while backup components are on standby. If an active component fails, a backup takes over.
**Use Case**: Database replication where the primary database is active and a replica database is on standby.
- **Active Redundancy**: Multiple nodes are active and handle traffic simultaneously. If one node fails, the others continue to handle the load.
Multiple components work simultaneously. If one fails, others continue to function without interruption.
**Use Case:** Load-balanced web servers where traffic is evenly distributed across multiple servers.
Let's explore three common redundancy architectures: **Hot-Cold, Hot-Warm, and Hot-Hot,** along with their pros and cons.
### Hot-Cold Architecture
In the Hot-Cold architecture, there is a primary instance that handles all client reads and writes, and a backup instance that remains idle until needed. The primary instance continuously synchronizes data to the backup instance. If the primary fails, manual intervention is required to switch clients over to the backup instance.
**Pros**: Simple and straightforward design.
**Cons**: Resource wastage due to the idle backup instance; potential for data loss depending on the last synchronization; manual intervention needed for failover.
### Hot-Warm Architecture
The Hot-Warm architecture optimizes resource utilization by allowing clients to read from the backup instance while the primary handles all writes. If the primary fails, clients can still read from the backup instance with reduced capacity.
**Pros**: Better resource utilization compared to Hot-Cold; reduced downtime for read operations during failover.
**Cons**: Potential for stale reads if data synchronization is not up-to-date; complexity in maintaining data consistency.
### Hot-Hot Architecture
In the Hot-Hot architecture, both instances act as primaries, handling reads and writes. This requires bidirectional state replication, which can lead to data conflicts if sequential ordering is needed.
**Pros**: High flexibility and resource utilization; continuous availability even if one instance fails.
**Cons**: Complexity in maintaining data consistency; potential for data conflicts in scenarios requiring sequential data.
### Failure Detection and Alerting
Redundancy alone is not enough. Systems must have mechanisms to detect failures and alert administrators. Continuous monitoring and regular high-availability testing are essential to take corrective action promptly.
### Load Balancing
Load balancing distributes incoming requests across multiple servers or resources to prevent overloading any single component and improve overall system performance and fault tolerance.
### Automatic Failover
Implement mechanisms for automatic failover so that if one component fails, another takes over its function automatically without manual intervention.
### Data Replication
Replicate data across multiple locations to avoid outages and make the system resilient against disasters. Replication can be synchronous or asynchronous, depending on the requirements.
`Note: will discuss more about this topic in upcoming articles`
### Performance Optimization and Scalability
Ensure the system is designed and tuned to handle the expected load efficiently, reducing the risk of bottlenecks and failures. Design the system to scale easily by adding more resources when needed to accommodate increased demand.
### High Availability Architectures
**Microservices**: Break down applications into smaller, independent services that can be deployed and scaled independently.
**Containerization:** Use container orchestration platforms like Kubernetes to manage and scale applications automatically.
**Service Mesh:** Implement a service mesh to manage service-to-service communication, security, and monitoring.
### Disaster Recovery (DR)
Have a comprehensive plan to recover the system in case of a catastrophic event that affects the primary infrastructure.
### Monitoring and Alerting
Implement robust monitoring systems that can detect issues in real-time and notify administrators to take appropriate action promptly.
## High Availability vs. Fault Tolerance
Both high availability and fault tolerance aim to achieve high uptime but approach the problem differently.
- **High Availability**: Focuses on minimizing downtime and may use software-based approaches, making it more flexible and easier to implement.
- **Fault Tolerance**: Ensures the system continues to function normally even during failures. It often requires multiple systems running in parallel and advanced hardware to detect and manage component faults.
Fault tolerance provides a higher level of protection against failures but can be more complex and costly to implement compared to high availability strategies.
## Conclusion
High availability is essential for systems where continuous operation is vital, and any disruption could lead to significant consequences. By employing redundancy, load balancing, automatic failover, data replication, and robust monitoring, system designers can ensure that their systems remain operational and accessible to users, even in the face of failures.

Today's lesson including configuring GitHub Pages went smoothly, including implementing GitHub's Pages and documentation features.
While Codecademy CSS lessons stand out for their breadth and depth, I have to give them credit for surgically going through every part of CSS. Their practical exercises are very effective for grasping the body of knowledge. I may be able to wrap up this lesson by end of day tomorrow.
However, what's giving me pause is the lesson plan for the last lesson in the first course, Making a Website Responsive, which includes Flexbox, CSS Grid, and Responsive Design with Media Query. I've not seen most of this, so it'll be exciting if I complete course assessments this weekend and start the JavaScript lesson in the next course on Monday.
Today I found some fun posts on Dev, including one on Restful API's, and learned that I'll bookmark hearted posts to refer back to them. | jacobsternx |
1,918,053 | Abordando grafos através das escalas musicais | Abordando grafos através das escalas musicais Como desenvolvedor de software e também... | 0 | 2024-07-10T04:30:05 | https://dev.to/magnojunior07/abordando-grafos-atraves-das-escalas-musicais-1fmj | java, datastructures, algorithms | ## Abordando grafos através das escalas musicais
Como desenvolvedor de software e também amante de música, embora não toque nenhum instrumento, mas com um raso conhecimento em teoria musical. Resolvi unificar essas duas coisas nesse artigo, para apresentar uma breve explicação sobre grafos e como implementar um algoritmo que traga a escala maior de determinada nota musical utilizando a estrutura de grafo.
### O que é um grafo?
A princípio, o que seria um grafo? Um grafo é uma estrutura de dados, baseada na teoria dos grafos (caso queira se aprofundar mais, leia sobre o problema das 7 pontes de Königsberg, de Leonhard Euler), organizada em vértices e arestas, onde os vértices são interconectados entre si através das arestas, seguindo um determinado padrão/regra que determine uma relação entre eles. Trazendo para dentro do contexto das escalas musicais, é sabido que a escala maior de **C (dó)** é: **D (ré), E (mi), F (fá), G (sol), A (lá), B (si), C (dó)**.
Desse modo, a vértice **C (dó)** estaria conectada às vértices **D (ré), E (mi), F (fá), G (sol), A (lá), B (si), C (dó)**
Na imagem acima está como ficaria o grafo seguindo a escala de C (dó), note que cada vértice que faz parte da escala maior de C (dó) está conectado na vértice C, as linhas fazendo essa conexão seriam as arestas.
### Implementando o algoritmo para a escala maior
A escala maior de uma nota consiste nas 7 notas em sequência seguindo o padrão: tom, tom, semitom, tom, tom, tom, semitom, a partir da nota tônica (a nota de onde está sendo tirada a escala). Esse tom e semitom seria a distância entre duas notas, ex: D (ré) está a um tom de distância de E (mi) que por sua vez está meio tom (semitom) de distância de F (fá).
Dado o contexto e qual o padrão para se obter uma escala maior de uma nota, nossa implementação em java ficaria assim:
```
package notesScale;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
public class MajorScaleGraph {
private int[] majorScalePattern = { 2, 2, 1, 2, 2, 2, 1 }; // iniciando um array com os passos de tom e semitom
private String[] notes = { "C", "C#", "D", "D#", "E", "F", "F#", "G", "G#", "A", "A#", "B" }; // inciando um array com as notas
private Map<String, List<String>> nodes = new HashMap<String, List<String>>(); // iniciando um hashmap para representar as vertices e com quais estao conectadas
private void addNode(String node) {
nodes.put(node, new ArrayList<String>()); // adicionando uma vertice no grafo
}
private void addEdge(String node, String value) {
List<String> edges = nodes.get(node);
edges.add(value); // adicinando uma aresta em um vertice, para conecta-lo em outro vertice.
nodes.put(node, edges); // atualizando as arestas do vertice
}
public void init() {
// percorre a lista de notas de gera a escala maior de cada uma
for (int i = 0; i < notes.length; i++) {
String note = notes[i];
addNode(note);
int nextNoteFromScaleIndex = i;
// executa o padrao e conecta nota encontrada na vertice da nota tonica da escala
for (int tone : majorScalePattern) {
nextNoteFromScaleIndex = (nextNoteFromScaleIndex + tone) % 12;
String nextNoteFromScale = notes[nextNoteFromScaleIndex];
addEdge(note, nextNoteFromScale);
}
}
}
// retorna a escala de acordo com a nota
public List<String> getMajorScaleFromNote(String note) {
List<String> majorScale = nodes.get(note);
return majorScale;
}
}
```
Essa seria a classe que representaria nosso grafo, nela tem toda a regra de negócio do nosso grafo e como ele deve funcionar.
A nossa classe principal ficaria assim:
```
package notesScale;
public class Main {
public static void main(String[] args) {
MajorScaleGraph graph = new MajorScaleGraph(); // instanciando nosso grafo
graph.init(); // chamando o metodo init para iniciar o grafo e ja conectar os vertices entre si
System.out.println(graph.getMajorScaleFromNote("C")); // tras a escala maior de acordo com a nota passada como parametro
// output: [D, E, F, G, A, B, C]
System.out.println(graph.getMajorScaleFromNote("D"));
// output: [E, F#, G, A, B, C#, D]
}
}
```
No final, depois de organizado nosso grafo ficaria organizado dessa forma:
### Conclusão
Neste artigo, foi abordado de forma bem simples um pouco do conceito e funcionamento de um grafo, sobre como ele é organizado, também foi implementando um algoritmo em java que gera as escalas maiores das notas musicais para exemplificar a estrutura de um grafo. Espero que tenham curtido e até mais. Obrigado pela leitura e pela atenção!

This guide will walk you through the steps to deploy your Django app to Vercel, ensuring everything goes smoothly from start to finish.
## Setting up Django for Vercel deployment
Start by going to your `wsgi.py` file and add `app = application` as shown
```py
import os
from django.core.wsgi import get_wsgi_application
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project.settings') # replace with your project name.settings
application = get_wsgi_application()
app = application # add this line for vercel, as it looks for app and not application
```
Now lets add a `vercel.json` file with the following
```py
{
"builds": [
{
"src": "project/wsgi.py",
"use": "@vercel/python",
"config": { "maxLambdaSize": "15mb", "runtime": "python3.12" }
},
{
"src": "build_files.sh",
"use": "@vercel/static-build",
"config": {
"distDir": "staticfiles"
}
}
],
"routes": [
{
"src": "/static/(.*)",
"dest": "/static/$1"
},
{
"src": "/(.*)",
"dest": "project/wsgi.py"
}
]
}
```
make sure to replace `"staticfiles"` with your own static files directory and the build's src to your project name.
Create a `build_files.sh` and add the following
```bash
#!/bin/bash
python3 -m pip install -r requirements.txt
python3 manage.py collectstatic --noinput
```
## Deploying to vercel
Once you have signed up to vercel, go ahead and create a project
Now import repository, if you don't find it then adjust the gihub app permissions.
Now give it a project name and click on deploy
Make sure to set `DEBUG=False` in `settings.py`, you may see an error asking you to add domain to allowed host, so add it and deploy it again.
That's it your deployment is ready!
## Environment variables
If you are using env variables, You can add environment variables by going to settings -> environment variables
then go to deployments and click on redeploy
## Debugging
If you are getting errors, click on the deployment and check the build logs to correct the error

As a seasoned human writer, I understand the importance of staying up-to-date with the latest technologies and frameworks in the ever-evolving world of web development. One such framework that has gained immense popularity in recent years is Laravel, a powerful and versatile PHP framework that has revolutionized the way developers build web applications.
Laravel's versioning system is a crucial aspect of its ecosystem, as it ensures that developers can keep their projects in sync with the latest updates, bug fixes, and security enhancements. In this comprehensive guide, we will explore the ins and outs of checking the Laravel version, providing you with the knowledge and [**Laravel development tools**](https://apptagsolution.com/blog/laravel-development-tools/) you need to effectively manage your Laravel projects.
Why it is Important to Check the Laravel Version
Keeping track of the Laravel version used in your project is essential for several reasons:
Compatibility: Ensuring that your project is running on the correct Laravel version is crucial for maintaining compatibility with the various components and dependencies that make up your application.
Security: Laravel, like any other software, is subject to security vulnerabilities. By regularly checking the version, you can stay informed about the latest security patches and updates, allowing you to proactively address any potential issues.
Feature Updates: Each new version of Laravel introduces new features, improvements, and enhancements. Knowing the version you're using can help you take advantage of the latest functionalities and optimize your development workflow.
Troubleshooting: When encountering issues or seeking support, the Laravel version you're using is often a critical piece of information that developers and the community need to provide accurate and relevant assistance.
Checking the Laravel Version Using the Command Line Interface (CLI)
One of the most straightforward ways to check the Laravel version is by utilizing the command line interface (CLI). This method is particularly useful for developers who prefer to work in a terminal or command prompt environment.
To check the Laravel version using the CLI, follow these steps:
Open your terminal or command prompt.
Navigate to the root directory of your Laravel project.
Run the following command:
php artisan --version
This command will display the version of Laravel installed in your project. For example, the output might look like this:
Laravel Framework 8.83.15
Step-by-Step Guide to Checking the Laravel Version in the Command Prompt
If you prefer a more detailed step-by-step guide, here's how you can check the Laravel version in the command prompt:
Open the Command Prompt: Depending on your operating system, you can access the command prompt by searching for "Command Prompt" in the search bar or by pressing the Windows key + R and typing "cmd" in the Run dialog box.
Navigate to the Project Directory: In the command prompt, use the cd (change directory) command to navigate to the root directory of your Laravel project. For example, if your project is located at C:\Users\YourUsername\Laravel-Project, you would type the following command and press Enter:
cd C:\Users\YourUsername\Laravel-Project
Run the Laravel Version Command: Once you're in the project directory, run the following command to check the installed version of Laravel:
php artisan --version
Observe the Output: The command prompt will display the version of Laravel installed in your project. For instance, the output might be:
Laravel Framework 8.83.15
This step-by-step guide ensures that you can easily check the Laravel version in the command prompt, regardless of your operating system or project location.
Alternative Methods to Check the Laravel Version in a Project
While the command line interface is the most common method, there are a few alternative ways to check the Laravel version in a project:
Using the Composer Command: If you have Composer (the dependency manager for PHP) installed, you can run the following command in your project's root directory:
Checking the composer.json File: The composer.json file in your project's root directory contains the dependencies and their versions. You can open this file in a text editor and look for the "laravel/framework" entry to find the installed version.
Inspecting the Application Version: In your Laravel project, you can create a route or a command that displays the application version. For example, you could create a route like this in your routes/web.php file:
Route::get('/version', function () {
return 'Laravel Version: ' . app()->version();
});
Then, by visiting the /version route in your browser, you'll see the installed version of Laravel.
These alternative methods provide additional ways to check the Laravel version, allowing you to choose the approach that best fits your workflow and preferences.
Common Issues and Troubleshooting When Checking the Laravel Version
While checking the Laravel version is generally a straightforward process, you may occasionally encounter some issues. Here are a few common problems and their potential solutions:
Command Not Found: If you receive an error stating that the php artisan command is not found, ensure that you're running the command from the correct directory (the project's root directory) and that you have PHP installed and properly configured in your system's environment variables.
Outdated Composer: If you're using the Composer command to check the Laravel version and it's returning an outdated version, make sure that you have the latest version of Composer installed. You can update Composer by running the following command:
Conflicting Versions: If you're working on a project that uses a specific Laravel version, but the php artisan --version command returns a different version, it's possible that you have multiple versions of Laravel installed on your system. In this case, you may need to check your project's composer.json file or use a tool like composer show to identify the correct version being used by the project.
By being aware of these common issues and their potential solutions, you can troubleshoot any problems you encounter when checking the Laravel version and ensure that your project is running on the correct version.
Best Practices for Managing and Updating Laravel Versions
To effectively manage and update the Laravel version in your projects, consider the following best practices:
Keep Your Dependencies Up-to-Date: Regularly update your project's dependencies, including the Laravel framework, to ensure that you're taking advantage of the latest features, bug fixes, and security enhancements.
Use Semantic Versioning: Laravel follows the Semantic Versioning (SemVer) system, which means that version numbers are structured as MAJOR.MINOR.PATCH. When updating Laravel, pay attention to the version number and understand the potential impact of the update on your project.
Implement Automated Dependency Management: Use tools like Composer to manage your project's dependencies, as they can automatically handle version conflicts and ensure that your project is using the correct versions of the required packages.
Maintain a Versioning Strategy: Develop a versioning strategy for your project that aligns with your development and deployment processes. This may include maintaining separate development, staging, and production environments with different Laravel versions.
Test Thoroughly: Before updating the Laravel version in your production environment, thoroughly test your application in a development or staging environment to ensure that the new version is compatible with your codebase and does not introduce any regressions.
Document Version Changes: Keep detailed records of the Laravel version changes in your project, including the reasons for the updates and any necessary adjustments made to your codebase. This will help you and your team maintain a clear understanding of the project's version history.
By following these best practices, you can effectively manage and update the Laravel version in your projects, ensuring that your applications stay secure, up-to-date, and compatible with the latest features and improvements.
Conclusion and Final Thoughts on Checking the Laravel Version
In conclusion, understanding how to check the Laravel version in your projects is a crucial skill for any [**Laravel developer**](https://apptagsolution.com/hire-laravel-developer/). By following the methods outlined in this guide, you can easily identify the version of Laravel installed in your project, enabling you to make informed decisions about updates, compatibility, and troubleshooting.
Remember, staying up-to-date with the latest Laravel versions is not only important for the health and security of your applications but also for your own professional development as a Laravel developer. By embracing the versioning system and best practices, you can ensure that your projects are always running on the most stable and feature-rich version of the Laravel framework. | apptagsolution |

I've... | 0 | 2024-07-10T06:54:30 | https://dev.to/ndutared/openstack-horizon-week-7-exploring-unit-testing-la1 | openstack, outreachy, cloud, django | Context: I was [accepted into Outreachy](https://dev.to/ndutared/my-outreachy-application-journey-28m1) a few weeks ago and I'm working on OpenStack Horizon.
I've been working with Cinder, which is Block Storage on OpenStack.
I've been spending my time learning how to write unit tests on the OpenStack Horizon project.
I hope to share my reflections and what I've learned about writing unit tests on OpenStack.
## Why Start With Unit Tests?
Unit tests are a great way to understand how various parts of the code interact with each other, and it's a[ highly recommended approach](https://www.youtube.com/watch?v=1IsJHWFGxlQ) by the OpenStack community.
The main idea around unit tests is testing the smallest "piece of code" possible, usually a function or method.
## Writing Unit Tests on OpenStack Horizon
I would like to begin by sharing some pitfalls to avoid.
**Polish up on your knowledge**
I would suggest polishing up on your unit testing basics first before attempting to write any unit tests. I'll share resources later on.
A lot of Cinder tests use mocking and patching. Learn about that too.
**Go through Existing Tests**
You also need to check how the rest of the tests are written. This will give you a clue about what's expected.
**Follow the Inheritance Trail**
Cinder code is basically Django classes, which means lots of inheritance. Make sure to follow the inheritance trail, all the way to the parent class.
That said, an example is always great.
### Prerequisites
- You have a working version of Horizon either on your PC or virtual machine.
- You have the latest code from master
- You have created some volumes on the Horizon dashboard
### A Unit Testing Example
I have horizon installed locally. I have created some volumes on my Horizon dashboard.
I need to write a test to determine whether the "AttachedTo" column on the Volumes table displays a dash [-], if the volume is not attached to an instance.
The first thing I need to do is find the code that generates the column on the volumes table.
You'll find it under
```python
horizon/openstack_dashboard/dashboards/project/volumes/tables.py
```
The specific class is AttachmentsColumn:
```python
class AttachmentColumn(tables.WrappingColumn):
"""Customized column class.
So it that does complex processing on the attachments
for a volume instance.
"""
instance_detail_url = "horizon:project:instances:detail"
def get_raw_data(self, volume):
request = self.table.request
link = _('%(dev)s on %(instance)s')
attachments = []
# Filter out "empty" attachments which the client returns...
for attachment in [att for att in volume.attachments if att]:
# When a volume is attached it may return the server_id
# without the server name...
instance = get_attachment_name(request, attachment,
self.instance_detail_url)
vals = {"instance": instance,
"dev": html.escape(attachment.get("device", ""))}
attachments.append(link % vals)
if attachments:
return safestring.mark_safe(", ".join(attachments))
```
The test essentially tests this code:
```python
if attachments:
return safestring.mark_safe(", ".join(attachments))
```
### Collecting the ingredients we need for our test
- Check your Python version (if older install [mock from PyPI](https://pypi.org/project/mock/))
- In newer versions, Python 3.3+ unitttest.mock is part of the library by default
- Think about what you want to test for (testing for None, equality, existence, truthiness, falsiness)
- In our case, we are testing for None, since the dash [-] translates to None
- Think about the scope of what you want to test. Do you want to write a test for the entire class? Or just the method? I went with the latter.
- That means that we need to create an instance of the AttachmentColumn class which inherits from tables.WrappingColumn.
- Let's explore this class more.
- The tables code is on this file path:
```python
/home/nduta/horizon/horizon/tables
```
- Go to the imports in the __init__.py and find WrappingColumn
```python
from horizon.tables.base import WrappingColumn
```
- The WrappingColumn is defined in base.py
```python
class WrappingColumn(Column):
"""A column that wraps its contents. Useful for data like UUIDs or names"""
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.classes.append('word-break')
```
- It inherits from Column, which is also defined in base.py
- In the __init__ method of Column, we see that the only required argument is "transform"
```python
def __init__(self, transform, verbose_name=None, sortable=True,
link=None, allowed_data_types=None, hidden=False, attrs=None,
status=False, status_choices=None, display_choices=None,
empty_value=None, filters=None, classes=None, summation=None,
auto=None, truncate=None, link_classes=None, wrap_list=False,
form_field=None, form_field_attributes=None,
update_action=None, link_attrs=None, policy_rules=None,
cell_attributes_getter=None, help_text=None):
```
- The docstrings suggest that is can be a string or callable.
```python
"""A class which represents a single column in a :class:`.DataTable`.
.. attribute:: transform
A string or callable. If ``transform`` is a string, it should be the
name of the attribute on the underlying data class which
should be displayed in this column. If it is a callable, it
will be passed the current row's data at render-time and should
return the contents of the cell. Required.
```
- We now have the attribute to use when creating an instance of AttachmentColumn.
#### Mocking
- To imitate the functionality of the AttachmentColumn class, we need to create some [mocks](https://docs.python.org/3/library/unittest.mock.html).Think about mocks as "mimics".
- We could mimic a table which is where the column we intend to test lives, for example.
- Mocks also come in handy because Horizon makes API calls to services like Cinder when to display volume information. We would need to "mimic" this API calls too.
- To display a volume, for example, we would need to send a request to Cinder, asking for volume information.
- We would also need to "mimic" a volume, in this case, with the attachments attribute being an empty list, since it has no attachments.
### Writing the Test
- We are going to use the aforementioned unittest.mock library which has a Mock() class to help us in "mimicking"
```python
def test_attachment_column(self):
column = volume_tables.AttachmentColumn("attachments")
column.table = mock.Mock()
column.table.request = mock.Mock()
volume = mock.Mock()
volume.attachments = []
result = column.get_raw_data(volume)
self.assertIsNone(result, None)
```
- We defined a method called "test_attachment_column"
- We then created an instance of AttachmentColumn. Since the class is contained in the tables module, we prefixed that. If you check the imports, the tables module is imported as volume_tables.
- We then created a mock of our table, request, and volume, with the attachments attribute being an empty list.
- In our code, we use mock.Mocks() because we did not explicitly import Mock.
```python
from unittest import mock
```
- We then called our method, get_raw_data from the AttachmentColumn, passing in our volume as an argument.
- Eventually, we created an assertion, assertIsNone, to confirm that our volume has no attachments, and that translates to 'None', our [-]
- Note that we need to call the method we test (*get_raw_data* in our case) and use assert to compare the result with what we expect to get.
### Checking the correctness of your test
- We use tox within the OpenStack ecosystem to run tests. You can run this command in horizon's root directory:
```python
tox -e py3.10 -- openstack_dashboard/dashboards/project/volumes/tests.py -r test_attachment_column
```
- If using a different python version, then your command should be
```python
tox -e <python_version> -- openstack_dashboard/dashboards/project/volumes/tests.py -r test_attachment_column
```
- Your test should pass.
```python
openstack_dashboard/dashboards/project/volumes/tests.py::VolumeIndexViewTests::test_attachment_column PASSED
```
- You can also edit code in AttachmentColumn and rerun the test command to confirm that the code works.
```python
#if attachments:
return safestring.mark_safe(", ".join(attachments))
```
- The test should now fail.
```python
openstack_dashboard/dashboards/project/volumes/tests.py::VolumeIndexViewTests::test_attachment_column FAILED
```
## A word on mocks
- We could have used Mock() interchangeably with MagicMock(), but the latter is more powerful, with more "bells and whistles" which could break your tests, or cause some to pass/fail due to default MagicMock behaviour.
## Forging Forward
There's still a lot to explore regarding unit tests within the OpenStack Horizon project. Some tests use pytest, for example, and others use the [patch()](https://docs.python.org/3/library/unittest.mock.html#unittest.mock.patch) decorator.
I hope that this blog would go a long way in helping you get started with unit testing in Horizon.

1,918,065 | How to implement Daily Database Backups in Laravel 11 | Note: In laravel 11, kernel.php is no longer present and these are handled through the... | 0 | 2024-07-10T04:58:35 | https://dev.to/arvindegiz/how-to-implement-daily-database-backups-in-laravel-11-2e10 | **Note: In laravel 11, kernel.php is no longer present and these are handled through the bootstrap/app.php file.**
Regular backups are essential for maintaining the integrity of your Laravel application and safeguarding against unexpected events like data loss, system failures, or malicious attacks. In this blog post, we will explore how to create a daily backup system for your Laravel 11 application using custom commands and Laravel’s Artisan command-line interface (CLI). We will also discuss the popular Laravel Backup package, which simplifies backup management.
Why Regular Backups Matter
Data loss can occur due to various reasons such as hardware failures, software bugs, or security breaches. Regular backups ensure that you can restore your application to its previous state, minimizing downtime and data loss. By automating the backup process, you can ensure consistency and reduce the risk of human error.
Using the Laravel Backup Package
The Laravel Backup package is a powerful tool that allows you to easily manage your application’s backups. It can back up your files and databases to various storage locations, including local disks, FTP, SFTP, Amazon S3, and more.
To get started with the Laravel Backup package in Laravel 11, follow these steps:
Step 1. Install the Laravel Backup Package
Use Composer to install the package:
composer global require laravel/installer
or
composer require spatie/laravel-backup
Step 2. Creating Custom Artisan Commands
php artisan make:command DatabaseBackup
Step 3. Defining the Custom Command
Open the generated command file and set the command signature and behavior. Here’s an example of how to define the command to back up the database:
and add this DatabaseBackup.php file
<?php
namespace App\Console\Commands;
use Carbon\Carbon;
use Illuminate\Console\Command;
use Illuminate\Support\Facades\Storage;
class DatabaseBackup extends Command
{
/**
* The name and signature of the console command.
*
* @var string
*/
protected $signature = ‘db:backup’;
/**
* The console command description.
*
* @var string
*/
protected $description = ‘Automating Daily Backups’;
/**
* Execute the console command.
*/
public function handle()
{
if (! Storage::exists(‘backup’)) {
Storage::makeDirectory(‘backup’);
}
$filename = “backup-” . Carbon::now()->format(‘Y-m-d’) . “.gz”;
$command = “mysqldump — user=” . env(‘DB_USERNAME’) .” — password=” . env(‘DB_PASSWORD’)
. “ — host=” . env(‘DB_HOST’) . “ “ . env(‘DB_DATABASE’)
. “ | gzip > “ . storage_path() . “/app/backup/” . $filename;
$returnVar = NULL;
$output = NULL;
exec($command, $output, $returnVar);
}
}
4. Scheduling the Backup Command
<?php
use Illuminate\Console\Scheduling\Schedule;
use Illuminate\Foundation\Application;
use Illuminate\Foundation\Configuration\Exceptions;
use Illuminate\Foundation\Configuration\Middleware;
return Application::configure(basePath: dirname(__DIR__))
->withRouting(
web: __DIR__.’/../routes/web.php’,
api: __DIR__.’/../routes/api.php’,
apiPrefix: ‘api’,
commands: __DIR__.’/../routes/console.php’,
channels: __DIR__.’/../routes/channels.php’,
health: ‘/up’,
)
->withMiddleware(function (Middleware $middleware) {
//
})
->withExceptions(function (Exceptions $exceptions) {
//
})
->withSchedule(function (Schedule $schedule) {
/**
* Define the application’s command schedule.
*/
$schedule->command(‘db:backup’)->daily();
})
->create();
In laravel 11, kernel.php is no longer present and these are handled through the bootstrap/app.php file.
Step 5: Run the Laravel scheduler.
php artisan db:backup run
this cmd for testing prupose
, and you can also see the backup file storage->app->backup folder
* * * * * cd /path-to-your-project && php artisan schedule:run >> /dev/null 2>&1
I hope it will help you.
Thank you

In software testing, achieving thorough test coverage is critical for ensuring the quality and reliability of an application. One of the key metrics used to measure test coverage is condition coverage. [Condition coverage](https://keploy.io/blog/community/understanding-condition-coverage-in-software-testing), also known as predicate coverage, goes beyond basic statement and branch coverage by examining the logical conditions within the code. This article delves into the concept of condition coverage, its significance, how it is measured, and best practices for achieving comprehensive condition coverage in your tests.
Understanding Condition Coverage
Condition coverage is a white-box testing technique that focuses on the evaluation of individual conditions within a decision-making statement. A condition is a Boolean expression that can evaluate to either true or false. Condition coverage requires that each condition in a decision statement be tested with both true and false outcomes at least once.
For example, consider the following code snippet:
java
Copy code
if (a > 0 && b < 5) {
// Perform some action
}
In this example, the decision statement consists of two conditions: a > 0 and b < 5. Condition coverage aims to ensure that each of these conditions evaluates to both true and false during testing.
Importance of Condition Coverage
1. Thorough Testing: Condition coverage ensures that each condition within a decision statement is tested, leading to more thorough and reliable tests.
2. Improved Fault Detection: By testing each condition individually, condition coverage helps identify edge cases and potential faults that might be missed with other coverage metrics.
3. Better Test Quality: Achieving condition coverage encourages the development of detailed and well-thought-out test cases, improving the overall quality of the test suite.
4. Enhanced Code Reliability: Comprehensive condition coverage increases confidence in the reliability of the code by ensuring that all possible outcomes of conditions are tested.
Measuring Condition Coverage
Condition coverage is measured by evaluating each condition within a decision statement and determining whether it has been tested with both true and false outcomes. The formula for calculating condition coverage is:
Condition Coverage=(Number of True and False Outcomes TestedTotal Number of Condition Outcomes)×100%\text{Condition Coverage} = \left( \frac{\text{Number of True and False Outcomes Tested}}{\text{Total Number of Condition Outcomes}} \right) \times 100\%Condition Coverage=(Total Number of Condition OutcomesNumber of True and False Outcomes Tested)×100%
For example, if a decision statement contains two conditions, each of which can be true or false, there are four possible condition outcomes. If all four outcomes are tested, the condition coverage is 100%.
Achieving Condition Coverage: Best Practices
1. Identify All Conditions: Begin by identifying all the conditions within your decision statements. This includes conditions in if, else if, while, for, and switch statements.
2. Write Comprehensive Test Cases: Develop test cases that explicitly test each condition with both true and false outcomes. Ensure that each condition is evaluated independently.
3. Use Coverage Tools: Utilize code coverage tools that support condition coverage metrics. These tools can help you track and measure condition coverage, highlighting areas that need additional testing.
4. Refactor Complex Conditions: For complex decision statements with multiple conditions, consider refactoring the code to simplify the conditions. This can make it easier to achieve comprehensive condition coverage.
5. Combine with Other Coverage Metrics: Condition coverage should be used in conjunction with other coverage metrics, such as statement coverage, branch coverage, and path coverage, to achieve a well-rounded testing strategy.
6. Review and Update Tests: Regularly review your test cases and update them as the code evolves. Ensure that new conditions introduced in the code are adequately tested.
Example of Achieving Condition Coverage
Consider the following Java code snippet:
java
Copy code
public class Calculator {
public String categorizeNumber(int a, int b) {
if (a > 0 && b < 5) {
return "Category 1";
} else if (a <= 0 && b >= 5) {
return "Category 2";
} else {
return "Category 3";
}
}
}
To achieve condition coverage for this code, we need to ensure that each condition (a > 0, b < 5, a <= 0, b >= 5) is tested with both true and false outcomes. Here are the test cases:
java
Copy code
import static org.junit.Assert.assertEquals;
import org.junit.Test;
public class CalculatorTest {
@Test
public void testCategorizeNumber() {
Calculator calc = new Calculator();
// Test case 1: a > 0, b < 5 (true, true)
assertEquals("Category 1", calc.categorizeNumber(1, 4));
// Test case 2: a > 0, b >= 5 (true, false)
assertEquals("Category 3", calc.categorizeNumber(1, 5));
// Test case 3: a <= 0, b < 5 (false, true)
assertEquals("Category 3", calc.categorizeNumber(0, 4));
// Test case 4: a <= 0, b >= 5 (false, false)
assertEquals("Category 2", calc.categorizeNumber(0, 5));
}
}
In this example, each condition is tested with both true and false outcomes, ensuring 100% condition coverage.
Challenges and Limitations
1. Complex Decision Statements: Achieving condition coverage can be challenging for complex decision statements with many conditions. This might require writing numerous test cases to cover all possible outcomes.
2. False Sense of Security: Condition coverage alone does not guarantee complete testing. It should be used alongside other coverage metrics to ensure comprehensive testing.
3. Maintenance Overhead: Maintaining condition coverage can be time-consuming, especially for large and evolving codebases. Regularly updating test cases to reflect code changes is essential.
Conclusion
Condition coverage is a valuable metric for enhancing the thoroughness and reliability of software tests. By ensuring that each condition within a decision statement is tested with both true and false outcomes, condition coverage helps identify edge cases and potential faults that might be missed with other coverage metrics. By following best practices and leveraging coverage tools, developers can achieve comprehensive condition coverage and deliver high-quality, reliable software. | keploy |

1,918,072 | React inside Ember - The Second Chapter | A year ago, I wrote an article here about invoking React components from Ember where I outlined an... | 0 | 2024-07-12T07:21:49 | https://dev.to/rajasegar/react-inside-ember-the-second-chapter-17bl | react, ember, javascript, webdev | A year ago, I wrote an article here about invoking React components from Ember where I outlined an approach of rendering React components inside Ember templates or components using a complex and sophisticated mechanism.
{% embed https://dev.to/rajasegar/invoking-react-components-from-your-ember-apps-3fgg %}
After trying it out in our organization, we have found that there are a lot of downsides and productivity concerns in implementing that approach.
## Limitations of the old approach
- Converting existing repo to a workspace or monorepo
- Setup complex build tooling with webpack
- Extra wrapper components for passing in props
- No hot module reloading support
- Cannot yield child components from Ember
## Advantages of the new approach
With the new addon approach by using the `ember-react-fc` addon, the process looks much simpler and we can overcome many downsides that were outlined in the previous post. Let's discuss the advantages of the new approach one by one here in detail.
### No workspace or monorepo setup required
With this new approach, you don't have to convert your repo to a monorepo or workspace like we did in the old one. You can simply put your React components inside the `app/components`, may be with a new namespace like `app/components/react` and use it like this:
```handlebars
<React::HelloWorld @name="Raja"/>
```
### No complex setup required
Previously, we have been compiling React component code using babel plugins using webpack config in Ember cli using the auto-import plugin. The problem with this approach is that, we need to install a lot of dependencies like babel plugins, react libraries and have to configure the webpack in such a way that it picks up only the files with JSX extensions referred from a different package inside a workspace.
### ember-react-fc
[ember-react-fc](https://github.com/rajasegar/ember-react-fc) is an Ember addon to incrementally migrate your Ember code starting from components to React. This addon supports the latest React version 18 and functional components. The addon takes care of a lot of things like adding the respective babel plugins to compile JSX, react and react-dom dependencies to your Ember projects, support for `.jsx` extensions inside your Ember apps and so on.
You can install it in your Ember projects like below and start writing your components in React and they will work out of the box.
```
ember install ember-react-fc
```
This addon also comes with a component blueprint so that you can also generate component boiler plates for your React component.
You can generate React components like this:
```
ember generate react-component hello-world
```
### No wrapper components required
In the old approach, we need to create Ember wrapper components for each React component we were creating. This creates an unnecessary overhead to have Ember duplicates for React components. But with this approach we are just invoking React components inside Ember templates and components in Ember way.
```handlebars
<div>
<h3>I am a Ember Component</h3>
<HelloReact @message={{this.message}}
@onClick={{this.toggle}} />
</div>
```
### Automatic reloading
In the old approach, we have kept our React components inside a (yarn or pnpm) workspace, so the changes inside this workspace won't affect the Ember build. Since Ember will only look for changes inside the `app/` folder, it was proving very difficult to propagate the changes in React components to Ember build pipeline.
This problem we overcame in the new approach since we are keeping the React components inside the Ember app itself, any change you make to your React components will automatically get picked up by ember-cli.
### React can have Ember children
There was no way previously to pass Ember components as children to React components in the old approach. But now you can put Ember components inside React as children. There is some room for misunderstanding here. What I meant by using Ember components as children is that when you are using the markup in your Ember templates, you can give Ember components as children to React components but not inside JSX in React.
This will work:
```handlebars
<React::HelloWorld @name="Raja">
<MyEmberComponent @arg1="abc" @arg2=true />
</React::HelloWorld>
```
This won't work:
```jsx
import React from 'react';
import WithEmberSupport from 'ember-react-fc';
export default WithEmberSupport(function FunctionalComponent({message, onClick}) {
return (
<div id="wrapper" aria-label="hello">
<button onClick={onClick}>Toggle</button>
<div>you said: {message}</div>
<MyEmberComponent @arg1="abc" @arg2=true />
</div>
);
});
```
This is a sample Ember app with the addon `ember-react-fc` installed and React components created and rendered inside Ember templates.
## Inspiration
The inspiration for this addon came from previous works by [Alex LaFroscia](https://github.com/alexlafroscia) like [ember-react-components](https://github.com/alexlafroscia/ember-react-components). But that project got abandoned some 3 years ago and it is not made for the latest React versions. I cleaned up the addon by removing the logic for class components, made it work with latest React v18, fixed some issues and so on.
Hope you enjoyed the post and let me know your feedback and thoughts in the comment section. Please give the addon a try and let me know for any issues.

if(weight[i] > j){
dp[i][j] = dp[i-1][j];
}else{
dp[i][j] = Math.max(dp[i - 1][j], dp[i - 1][j - weight[i]] + value[i]);
}
}
}
System.out.println(dp[M-1][N]);
}
}
```
1, the dp array means that we can obtain the maximum value for item `i` and target bag size `j`. The row indicates the item, and the column represents the size of the bag.
2, for init, we init the 1st row and 1st col( but actually we init the col by default 0, that mean )
3, the regression relation is that: for each item:
a, if the weight of the item is heavier than the bag's size, we cannot choose the item and the current size is the size of the collection of the previously chosen items.
b, if the weight of the item is ok, we have to compare the size of the collection of the previously chosen items minus the size of the current item (if we do not do it, the total size will be the size + the size of the current item, it will break the logic of our dp array).
Here, is the order of the double loop, because we can use a 2-D array to record all results and search for the current row from the previous row.
## Also, we can use a 1-D array to realize it.
<be>
```
for(int i=1; i<M; i++){
for(int j=1; j<=N; j++){
if(weight[i] > j){
dp[i][j] = dp[i-1][j];
}else{
dp[i][j] = Math.max(dp[i - 1][j], dp[i - 1][j - weight[i]] + value[i]);
}
```
## change to
```
int[] dp = new int[target+1];
```
```
for(int i=1; i<nums.length; i++){
for(int j=target; j>=1; j--){
if(nums[i] > j){
continue;
}
dp[j] = Math.max(dp[j], dp[j-nums[i]] + nums[i]);
}
}
```

Whether you're a beginner or an experienced developer, mastering Git commands will help you manage codebases, track changes, and contribute to projects seamlessly. You will learn the fundamental Git commands that are at the core of version control workflow in this introduction.
##What is Git?
A distributed version control system, Git, is designed to handle both small and large projects quickly and efficiently. This allows multiple developers to work on the same project without overwriting each other's changes, ensuring code integration that is cohesive and conflict-free.
## Why Use Git?
**Version Control:** Using Git, you can track every change made to your codebase and revert to previous versions if necessary.
**Collaboration:** When multiple developers are working on a project simultaneously, their changes are seamlessly merged.
**Branching and Merging:** GitHub's branching model enables developers to work independently before merging new features or bug fixes.
**Distributed System:** Developers have their own copies of the entire project history, which allows for faster operations and backups.
## Setting Up Git
Before you can start using Git, you need to set it up on your local machine.
**1. Install Git**
```
# For Debian-based distributions like Ubuntu
sudo apt-get install git
# For Red Hat-based distributions like Fedora
sudo dnf install git
# For macOS
brew install git
# For Windows, download and install from https://git-scm.com/
```
**2. Configure Git**
The username and email you specify when configuring Git are associated with your commit messages. Using the `--global flag`, you can set these configurations for all repositories on your system.
```
# Set your name
git config --global user.name "Your Name"
# Set your email
git config --global user.email "your.email@example.com"
# Verify your settings
git config --list
```
##Key Git Commands
##Basic Git Operations
These are the foundational commands that you will use frequently.
**1. Initialize a New Repository**
Initializes a new Git repository in the current directory, along with a subdirectory called .git.
```
git init
```
**2. Clone an Existing Repository**
Makes a copy of an existing remote repository on your local machine.
```
git clone https://github.com/username/repository.git
```
**3. Check the Status of Your Repository**
It shows the current state of the working directory as well as the staging area. Git shows which changes have been staged, which haven't, and which files aren't being tracked.
```
git status
```
**4. Add Files to the Staging Area**
Prepares the changes in the working directory for inclusion in the next commit by adding them to the staging area.
```
# Add a single file
git add filename
# Add all files
git add .
```
**5. Commit Changes**
A message is added to the repository that describes the changes made to the staging area.
```
git commit -m "Your commit message"
```
**6. View Commit History**
Display Lists all commits in the current branch, starting from the most recent.
```
git log
```
## Branching and Merging
Branching allows you to create separate environments for development, while merging integrates changes from different branches.
**1. Create a New Branch**
This command creates a new `branch` called new-branch.
```
git branch new-branch
```
**2. Switch to a Branch**
Changes the working directory to the branch specified
```
git checkout new-branch
```
**3. Create and Switch to a New Branch**
Switches immediately to the newly created branch.
```
git checkout -b new-branch
```
**4. Merge a Branch**
The changes from new-branch are merged into the main branch. It is typically done after a feature is complete or a fix is made on a separate branch.
```
git checkout main
git merge new-branch
```
**5. Delete a Branch**
This command deletes the specified branch. A branch is usually removed after it has been merged into another branch.
```
git branch -d new-branch
```
**5. Delete a Branch**
This command deletes the specified branch. In most cases, this is done after the branch has been merged into another branch and is no longer needed.
```
git branch -d new-branch
```
## Undoing Changes
Sometimes you need to undo changes, whether they are in your working directory, staging area, or committed history.
1. Discard Changes in Working Directory
Reverts the file to its last committed state by discarding changes in the working directory.
```
git checkout -- filename
```
**2. Unstage Changes**
Keeps changes in the working directory but removes them from the staging area.
```
git reset HEAD filename
```
**3. Amend the Last Commit**
Commits a new message or additional changes to the most recent commit.
```
git commit --amend -m "New commit message"
```
**4. Revert a Commit**
An undo commit is created by undoing a commit specified in the commit string.
```
git revert commit-hash
```
**5. Reset to a Previous Commit**
This command resets the current branch to the commit specified. If the `--soft` option is selected, the changes will be kept in the working directory, whereas if the `--hard` option is selected, they will be discarded.
```
# Soft reset (keeps changes in working directory)
git reset --soft commit-hash
# Hard reset (discards changes)
git reset --hard commit-hash
```
## Collaboration
Collaborating with others involves working with remote repositories.
**1. Add a Remote Repository**
The URL of a remote repository is associated with a name, typically the origin.
```
git remote add origin https://github.com/username/repository.git
```
**2. Push Changes to Remote Repository**
The local branch commits are uploaded to the corresponding branch in the remote repository.
```
git push origin branch-name
```
**3. Pull Changes from Remote Repository**
Syncs the remote branch with the current branch and fetches and integrates the changes.
```
git pull origin branch-name
```
**4. Fetch Changes from Remote Repository**
Updates are retrieved without being merged into the local branch from the remote repository.
```
git fetch origin
```
## Advanced Git Commands
For more complex workflows, these advanced commands can be very useful.
**1. Stash Changes**
Stacks unfinished changes in the working directory, allowing you to move on to something else without losing your work.
```
git stash
```
2. Apply Stashed Changes
Updates the working directory with the most recent changes.
```
git stash apply
```
**3. View Stashed Changes**
All stashes are listed, along with their names and commit messages.
```
git stash list
```
**4. Cherry-pick a Commit**
The current branch is updated with the changes from a specific commit.
```
git cherry-pick commit-hash
```
**5. Rebase a Branch**
Creates a linear project history by reapplying commits from the current branch onto another branch.
```
git rebase branch-name
```
##Tips and Tricks of git
Enhance your Git experience with these helpful tips.
**1. Aliases**
Save time and keystrokes by defining shortcuts for commonly used Git commands.
```
# Create an alias for git status
git config --global alias.st status
# Create an alias for git log with a specific format
git config --global alias.lg "log --oneline --graph --all"
```
**2. Autocorrect**
Ensures that mistyped commands are automatically corrected after a short delay after they are entered.
```
git config --global help.autocorrect 1
```
**3. Colorize Git Output**
Provides color-coded output for Git commands to make them easier to read.
```
git config --global color.ui auto
```
**Conclusion**
Having a clear understanding and use of these fundamental Git commands will greatly improve your workflow as a software engineer as well as your productivity. As a result of Git's robust version control capabilities, as well as its robust branching and merging features, Git has become one of the most indispensable tools for modern software development.

The primary endpoint for DOCSCAN is `https://api.pixlab.io/docscan`. You can make GET or POST requests to this endpoint, depending on your preference for uploading the document image.
#### 3. Making a Request
Here’s a simple example using JavaScript to scan a passport image:
```javascript
const apiKey = 'YOUR_PIXLAB_API_KEY'; // Replace with your PixLab API Key
const imageUrl = 'http://example.com/passport.png'; // URL of the passport image
const url = `https://api.pixlab.io/docscan?img=${encodeURIComponent(imageUrl)}&type=passport&key=${apiKey}`;
fetch(url)
.then(response => response.json())
.then(data => {
if (data.status !== 200) {
console.error(data.error);
} else {
console.log("Cropped Face URL: " + data.face_url);
console.log("Extracted Fields: ", data.fields);
}
})
.catch(error => console.error('Error:', error));
```
#### 4. Handling the Response
The API responds with a JSON object containing the scanned information. This includes URLs to the cropped face image and detailed extracted fields like full name, issuing country, document number, and more.
### Additional Code Samples
#### Python
#### PHP
#### Ruby
#### Java
```java
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import org.json.JSONObject;
public class DocScanExample {
public static void main(String[] args) {
try {
String apiKey = "YOUR_PIXLAB_API_KEY"; // Replace with your PixLab API Key
String imageUrl = "http://example.com/passport.png"; // URL of the passport image
String urlStr = "https://api.pixlab.io/docscan?img=" + java.net.URLEncoder.encode(imageUrl, "UTF-8") + "&type=passport&key=" + apiKey;
URL url = new URL(urlStr);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String inputLine;
StringBuilder content = new StringBuilder();
while ((inputLine = in.readLine()) != null) {
content.append(inputLine);
}
in.close();
conn.disconnect();
JSONObject data = new JSONObject(content.toString());
if (data.getInt("status") != 200) {
System.out.println("Error: " + data.getString("error"));
} else {
System.out.println("Cropped Face URL: " + data.getString("face_url"));
System.out.println("Extracted Fields: " + data.getJSONObject("fields").toString());
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
```
### Comprehensive HTTP Response
The DOCSCAN API endpoint always returns a JSON object. Below are the fields typically included in the response:
- `status`: HTTP status code (200 indicates success).
- `type`: Type of the scanned document.
- `face_url`: URL to the cropped image of the face from the document.
- `mrz_raw_text`: Extracted raw MRZ text (for Passports and Visas only).
- `fields`: A JSON object containing extracted data such as:
- `fullName`
- `issuingCountry`
- `documentNumber`

### How Does the PixLab DocScan Work?
Here’s what happens when you scan a driving license using the DocScan API:
1. The user’s face is detected using the face detect API.
2. After getting the face coordinate, you can crop and extract the image using the image processing API from PixLab.
3. Then, using the DocScan API, PixLab extracts the information about the user.
4. After processing is done, the image is deleted from the server. PixLab doesn’t store any of the images for future reference, ensuring privacy.
PixLab uses PP-OCR, a practical ultra-lightweight OCR system that consists of:
- Text Detection
- Bounding Box Isolation
- Text Recognition
This enables PixLab to generate accurate results by scanning a driver’s license.
### Real-World Example
Suppose you want to verify a user's passport. By using the DOCSCAN API, you can extract all relevant details and store them in your database for future reference. The API also crops the user's face from the passport image, which can be used for profile verification.
#### App.jsx
```jsx
// components/DocScanComponent.jsx
import { useState } from 'react';
import axios from 'axios';
const DocScanComponent = () => {
const [imageUrl, setImageUrl] = useState('');
const [scanResult, setScanResult] = useState(null);
const [loading, setLoading] = useState(false);
const [error, setError] = useState(null);
const apiKey = 'YOUR_PIXLAB_API_KEY';
const handleScan = async () => {
setLoading(true);
setError(null);
try {
const response = await axios.get('https://api.pixlab.io/docscan', {
params: {
img: imageUrl,
type: 'passport',
key: apiKey,
},
});
if (response.data.status !== 200) {
setError(response.data.error);
} else
{
setScanResult(response.data);
}
} catch (err) {
setError('Error scanning document');
} finally {
setLoading(false);
}
};
return (
<div>
<h1>DocScan</h1>
<input
type="text"
placeholder="Enter Image URL"
value={imageUrl}
onChange={(e) => setImageUrl(e.target.value)}
/>
<button onClick={handleScan} disabled={loading}>
{loading ? 'Scanning...' : 'Scan Document'}
</button>
{error && <p style={{ color: 'red' }}>{error}</p>}
{scanResult && (
<div>
<h2>Scan Result:</h2>
<img src={scanResult.face_url} alt="Cropped Face" />
<pre>{JSON.stringify(scanResult, null, 2)}</pre>
</div>
)}
</div>
);
};
export default DocScanComponent;
```
This is a demo passport image. The extracted data using Pixlab Docscan API is listed below.

Designing An Integration Testing Strategy For Agile: Best Practices And Guidelines
In the Agile method for developing software, testing how different parts work together is crucial. It makes sure that all pieces fit and function as one complete system. Agile is different from old methods because it focuses on little-by-little progress, which means businesses need a flexible plan for this kind of testing to adapt as things change. There are numerous benefits of integration testing, so when planning integration testing for Agile, it's important to think about these recommended practices and advice:
Designing An Integration Testing Strategy For Agile: Best Practices And Guidelines
**Start early, test continuously**
In Agile, it's good to start testing as soon as you can when developing and do tests over and over again during the whole process. You should put together individual parts created and test them early on. This method is useful for finding problems with integration soon, which lets us solve them quickly and lowers the chance of many defects building up.
**Identify integration points**
Carefully study the structure of the system and find where different parts connect. These points can be things like APIs, databases, services from other companies, and interfaces for users. To create a good plan for integration testing, it is important to know how the different parts depend on each other and interact.
**Prioritize test scenarios**
First, identify the most critical integration test cases and how they affect system operations. Begin with tests that examine areas of high risk, complicated interactions between components, and processes crucial to the business. When you put test cases in order of importance, it helps to use testing resources better and makes sure that all important parts of the system are checked well.
**Implement test automation**
Automation plays a key role in Agile integration testing, as it allows for quick and frequent running of test cases. Put in place automated test groups to check the connections where systems come together, mimic how users would act, and confirm how the system acts under different situations. Automated tests improve how fast you work, help with the ongoing mixing of new code and putting it to use easily and make quicker responses possible for Agile teams.
**Adopt TDD approach**
In Test-Driven Development, you write the tests first before making the code. It helps to concentrate on how easy it is to test and shape the creation of software parts. Put integration tests into this TDD method by setting clear acceptance standards and behaviors you want at the start. TDD encourages teamwork between the people who write code and those who test it, improves how good the code is, and makes sure that tests for combining parts of the software are a main part of making the software.
**Monitor and measure test coverage**
Consistently check and evaluate how much of the testing covers to judge if strategy for integration tests works well. Keep an eye on the amount of code that the integration tests include and find where there are missing parts in the testing coverage. Keep working to get better at covering tests by putting in new scenarios for testing, making current tests better, and focusing on parts where coverage isn't enough.
**Iterate and adapt**
Integration testing in Agile is a repetitive process that grows as the software product develops. Frequently revise and adjust integration testing plans according to feedback, what you have learned, and shifts in project needs. Keep improving your thinking, make better the way you test, and change to fit what your Agile team needs as things keep changing.
**Conclusion**
In the ever-changing world of Agile software development, creating a good plan for integration testing is essential for the projects to succeed. This is not only about finding mistakes; it's also about making sure that all parts of the software work well together without problems. The guidelines mentioned above are a good base, but if you have the proper tools, they can improve how well your testing works.

Unlike residential real estate, commercial land is used for business purposes, including retail, office spaces, industrial complexes, and more. This blog will provide an educational overview of commercial land, its benefits, key considerations for investing, and the development process.
**What is Commercial Land?
****[Commercial land](https://beyondcommercial.com/land/)** is a category of real estate designated for business activities. This land can be used for various purposes, including:
**Retail:** Shopping centers, malls, and standalone retail stores.
**Office:** Office buildings and business parks.
**Industrial:** Warehouses, factories, and distribution centers.
**Mixed-Use:** Developments that combine residential, commercial, and sometimes industrial uses.
**Benefits of Investing in Commercial Land
Income Potential:** Commercial properties typically generate higher rental income compared to residential properties. Businesses are often willing to pay a premium for prime locations.
**Long-Term Leases:** Commercial leases are usually longer-term, providing more stability and predictability in income. Lease agreements can range from 5 to 20 years or more.
**Appreciation:** Over time, commercial land can appreciate significantly, especially in high-demand areas. As cities expand and populations grow, the value of well-located commercial land often increases.
**Tax Advantages:** There are various tax benefits associated with owning commercial real estate, including deductions for mortgage interest, property depreciation, and operating expenses.
**Key Considerations for Investing in Commercial Land
Location:** The location of commercial land is crucial. Proximity to major roads, public transportation, and population centers can significantly impact the value and attractiveness of the property.
**Zoning Laws:** Understanding local zoning laws and regulations is essential. These laws dictate what types of businesses can operate on the land and can influence the potential uses and value of the property.
**Market Demand:** Researching the local market demand for different types of commercial properties can help determine the best use for the land. For instance, an area with a growing population might have a high demand for retail or office space.
**Infrastructure and Utilities:** Availability of infrastructure such as roads, water, electricity, and sewage systems is vital for the development of commercial land. Properties with readily available utilities are generally more valuable.
**Environmental Concerns:** Assessing any environmental issues, such as soil contamination or flood risks, is critical. Addressing these issues can be costly and time-consuming.

**Financing:** Secure financing for the project through loans, investors, or other funding sources. Preparing a detailed business plan and financial projections can help attract investors and lenders.
**Construction:** Once all plans and permits are in place, construction can begin. Hiring experienced contractors and project managers is essential to ensure the project stays on schedule and within budget.
**Marketing and Leasing:** As construction nears completion, start marketing the property to potential tenants or buyers. Effective marketing strategies and competitive lease terms can attract high-quality tenants.
**Management and Maintenance:** After leasing the property, ongoing management and maintenance are crucial to ensure the property remains in good condition and retains its value. This includes handling tenant relations, property upkeep, and financial management.
**Trends in Commercial Land Development
Sustainability:** There is a growing emphasis on sustainable and environmentally-friendly development practices. This includes using green building materials, incorporating energy-efficient systems, and designing spaces that promote healthy living.
**Mixed-Use Developments:** Mixed-use developments are becoming increasingly popular. These projects combine residential, commercial, and sometimes industrial uses, creating vibrant, multi-functional communities.
**Technology Integration:** Modern commercial properties are incorporating advanced technologies such as smart building systems, high-speed internet, and enhanced security features. These technologies can improve operational efficiency and attract tech-savvy tenants.
**Flexible Spaces:** The demand for flexible workspaces, such as co-working spaces, is rising. These spaces cater to the needs of small businesses, freelancers, and remote workers, offering adaptable and affordable office solutions.
**Urbanization:** As urban populations continue to grow, there is a higher demand for commercial spaces in city centers. Developers are focusing on creating high-density, pedestrian-friendly developments that integrate seamlessly into urban environments.
****Challenges in Commercial Land Development
**Regulatory Hurdles:** Navigating complex zoning laws, building codes, and permit processes can be challenging and time-consuming. Engaging with local authorities early in the process can help streamline approvals.
**Market Volatility:** Commercial real estate markets can be volatile, influenced by economic conditions, interest rates, and industry trends. Conducting thorough market research and risk assessments is crucial.
**Financing: **Securing financing for commercial projects can be challenging, especially for large-scale developments. Lenders and investors require detailed business plans and financial projections.
**Construction Risks:** Construction projects often face delays, cost overruns, and unforeseen issues. Effective project management and contingency planning can help mitigate these risks.
**Tenant Acquisition:** Attracting and retaining tenants requires effective marketing strategies and competitive lease terms. Building strong relationships with tenants can lead to long-term occupancy and stability.
**Conclusion**
Investing in and developing **[commercial land](https://beyondcommercial.com/land/)** offers significant opportunities for income, appreciation, and long-term growth. By understanding the key considerations, following a structured development process, and staying informed about industry trends, investors and developers can successfully navigate the complexities of commercial real estate.

1,918,153 | 9 Considerations While Choosing the Best QuickBooks Desktop Cloud Hosting Service | QuickBooks is the leader in accounting software solutions worldwide. However, combined with the power... | 0 | 2024-07-10T06:44:51 | https://dev.to/him_tyagi/9-considerations-while-choosing-the-best-quickbooks-desktop-cloud-hosting-service-3ag5 | webdev, javascript, beginners, programming | QuickBooks is the leader in accounting software solutions worldwide. However, combined with the power of cloud computing, it becomes even more robust and versatile. Having realized this, most organizations worldwide have started planning for cloud migration.
But before they can reap the benefits of QuickBooks Cloud, they need to encounter various roadblocks, the biggest of which is the search for the best QuickBooks Desktop Cloud hosting service.
As numerous QB hosting providers are available in the market, it becomes challenging to analyze each individually. Moreover, all the providers offer a plethora of services to choose from.
Specific considerations will help you opt for the best [QuickBooks Desktop cloud hosting service](https://www.acecloudhosting.com/quickbooks-enterprise-hosting/), no matter what services the providers offer. Let’s dig deep.
## 1. Data Security
The QuickBooks data contains critical information you can’t afford to compromise. By migrating your QB Desktop to the cloud, you give the cloud hosting provider access to your data.
Hence, they have the responsibility to keep it safe. Therefore, data security should be your top priority when choosing a QuickBooks Desktop cloud hosting service.
The cloud hosting provider should be able to protect your data at all levels - physical, Network, and endpoint.
Firstly, at the physical level, your QuickBooks Desktop and data should be hosted in [data centers with multiple security checks](https://learn.microsoft.com/en-us/compliance/assurance/assurance-datacenter-physical-access-security) and 24/7 CCTV surveillance, etc.
Secondly, data should be protected at the network level with multiple firewalls, 24/7 traffic monitoring, brute force protection, etc.
At the endpoint level, the provider must implement safeguards, such as multi-factor authentication, access controls, and antivirus/antimalware without fail.
## 2. Uptime Guarantee
Your accounting process is always ongoing. Hence, you can’t afford to lose access to your QuickBooks even for a second
The QuickBooks cloud hosting provider should guarantee an uptime level in their [SLA (Service Level Agreement)](https://www.cio.com/article/274740/outsourcing-sla-definitions-and-solutions.html). An SLA-backed uptime guarantee means the provider is contractually bound to offer you the uptime mentioned.
The best providers in the market offer an uptime guarantee of 99.99%. It means there is a maximum downtime of only six minutes a year.
## 3. Customer Support
Customer support is another crucial consideration when choosing a QuickBooks Desktop cloud hosting service. If an issue arises while working remotely on QuickBooks Desktop, the provider should be able to resolve it in time. Otherwise, operations could be halted.
The QB desktop cloud hosting provider must offer 24/7 customer support, 365 days a year. It's important to know that some providers don’t give support on weekends.
Hence, if an issue arises while working on the weekends, the team resolves it on weekdays. Moreover, the technical support team must be available through multiple channels - call, chat, and email- to ensure quick response time.
## 4. IT Infrastructure
Regarding cloud hosting, the provider's IT infrastructure is a primary consideration. The services offered by the provider may be exciting. But, if the cloud setup (where your QuickBooks and accounting data are hosted) could be better, you should think twice before choosing them.
Prefer a provider that hosts your data in a Tier 4+ data center. These data centers deploy server, power, and cooling redundancy, ensuring continuous operations even if there is a crisis in the data center.
Moreover, the provider should host your QuickBooks in a High-performance Computing (HPC) environment. An HPC setup ensures zero latency, giving you the best working experience.
## 5. Free Trial
Even when buying your apparel, you want to try it first. So, why should it be different when choosing your QuickBooks Desktop cloud hosting provider? Selecting a provider without striving can lead to vendor lock-in, hampering operational efficiency.
Shortlist a QuickBooks Desktop cloud hosting service that offers a free trial. This way, you will get a first-hand experience of the provider’s services to make the right decision.
Also, some providers only offer a part of their services in the free trial, which gives you a partial picture. You can ask the provider if the free trial includes all hosting features.
## 6. Intuit Authorized
You should prefer an Intuit Authorized one while searching for a QuickBooks hosting provider.
Due to its partnership with Intuit, an Intuit Authorized Host can offer you exclusive services compared to others.
For instance, an authorized hosting provider offers customer support directly from Intuit if you have any issues with the software.
Moreover, you can also purchase genuine QuickBooks licenses from them, taking care of your software requirements, like upgrades and license management.
## 7. Pricing Plans
Pricing is the most common obstacle when choosing a QuickBooks Desktop cloud hosting service.
Sometimes, everything about the cloud provider seems fine, but the charges are outside your budget. Also, some providers offer fixed pricing plans with a set of services that you don’t require.
Ask the cloud provider if they can customize the pricing plans according to your resource requirements. Moreover, check for hidden charges to avoid any unpleasant surprises in the bill.
## 8. Business Continuity and Disaster Recovery
Any data center can be subject to natural disasters, and human-caused accidents can happen at any data center, leading to downtime for days.
Hence, when choosing a QuickBooks desktop cloud hosting service, ensure that the provider deploys business continuity and disaster recovery safeguards.
To implement a [disaster recovery plan](https://www.ready.gov/business/emergency-plans/recovery-plan), the provider replicates the entire accounting process in multiple data centers in distant locations.
For instance, QB and data are replicated in Boston and Texas data centers. Hence, your data is safe in Texas if a disaster strikes at the Boston data center.
## 9. Hosting Services Offered
The QB cloud hosting providers offer two types of services depending on the cloud deployment methods. You can choose the cloud service provider according to your requirements and budget constraints.
These services are:
**Public cloud** - By choosing public cloud services, you share the server resources with multiple users on a load-sharing basis. You can avail of this service on a pay-per-use basis at nominal charges.
**Private Cloud**— Unlike the public cloud, private cloud service providers offer dedicated resources on the cloud. Although the private cloud is more expensive than the public cloud, it offers an added layer of security as the resources are not shared.
Some providers offer private and public cloud services, and some offer hybrid cloud services, combining private and public cloud services. It is up to you to choose the services best suited for your business.
### Wrapping Up!
Your journey to cloud migration starts with choosing the right QuickBooks Dekstop cloud service provider.
Hence, any wrong choice can lead to long-term budget, performance, availability, and support issues. Considering these parameters will help you choose a QuickBooks cloud hosting provider that will elevate your accounting process to the next level.
ACE is an Intuit Authorized QuickBooks hosting provider that offers enterprise-grade security, round-the-clock support, and an SLA-backed 99.99% uptime guarantee.

Black box testing adalah metode pengujian perangkat lunak di mana penguji tidak mengetahui struktur internal atau implementasi dari aplikasi yang diuji. Fokusnya adalah pada input dan output dari sistem, bukan bagaimana sistem tersebut bekerja di dalamnya. Pengujian ini bertujuan untuk memvalidasi fungsionalitas aplikasi berdasarkan persyaratan yang telah ditentukan.
**Ciri-ciri Black Box Testing**:
**Tidak perlu tau detail implementasi**: Penguji tidak perlu tahu bagaimana kode ditulis atau bagaimana logika internal bekerja.
**Fokus pada fungsionalitas**: Penguji mengevaluasi apakah aplikasi berfungsi sesuai dengan spesifikasi dan persyaratan.
**Berdasarkan spesifikasi**: Pengujian dilakukan dengan mengacu pada dokumen spesifikasi dan kebutuhan bisnis.
## Test-Driven Development (TDD)
Test-Driven Development (TDD) adalah pendekatan pengembangan perangkat lunak di mana pengembang menulis tes otomatis sebelum menulis kode yang diujinya. Proses ini melibatkan siklus berulang yang dikenal sebagai **“Red-Green-Refactor”**:
**Red**: Menulis tes yang gagal karena fitur belum diimplementasikan.
**Green**: Menulis kode minimal yang membuat tes berhasil.
**Refactor**: Merapikan kode dengan tetap memastikan bahwa semua tes tetap berhasil.
Dalam konteks TDD, black box testing dapat digunakan untuk menulis tes yang berfokus pada perilaku fungsional dari komponen aplikasi tanpa memperhatikan implementasi detailnya. Dengan demikian, TDD membantu memastikan bahwa setiap unit kode berfungsi sesuai harapan sebelum melanjutkan pengembangan lebih lanjut.
## Behavior-Driven Development (BDD)
Behavior-Driven Development (BDD) adalah pendekatan pengembangan perangkat lunak yang mengembangkan TDD dengan lebih menekankan kolaborasi antara tim Dev, tim QA dan Product Owner. BDD menggunakan bahasa yang lebih mudah dimengerti oleh semua pihak untuk menulis spesifikasi tes, sering kali dalam bentuk **Given-When-Then**.
## Given-When-Then:
**Given**: Keadaan awal sebelum aksi dilakukan.
**When**: Aksi atau peristiwa yang memicu suatu perilaku.
**Then**: Hasil atau reaksi yang diharapkan dari aksi tersebut.
BDD menggabungkan black box testing dalam cara penulisan spesifikasi yang fokus pada perilaku sistem berdasarkan persyaratan bisnis tanpa perlu memahami detail implementasi teknisnya. Tes BDD sering kali ditulis dalam bahasa yang mudah dimengerti oleh orang-orang non-teknis.
## Hubungan antara Black Box Testing, TDD, dan BDD
jika dilihat dari pendekatan yang digunakan ketika mengetes sistem dengan TDD dan BDD maka dapat dikatakan bahwa keduanya merupakan implementasi dari Black Box Testing. | triasbrata |
1,918,156 | Automated Regression Testing: Unveiling The Benefits Of Software Testing Efficiency | In the domain of software development, it is crucial to make sure that software products are... | 0 | 2024-07-10T06:50:56 | https://frasesdebuenosdias.com/automated-regression-testing-unveiling-the-benefits-of-software-testing-efficiency/ | automated, regression, testing | 
In the domain of software development, it is crucial to make sure that software products are reliable and of high quality. An essential way for achieving this goal is the use of automated tests that check previous programing features when new changes are made. As software systems get more complex and bigger, it becomes clear that businesses need good ways to test them. In this post, we will look at how regression testing automation changes the way companies perform software tests.
**Enhanced efficiency and time savings**
Automated regression testing cuts down on the time and work needed to test the software again after code changes. Different from manual testing, where testers have to do the same tests over by hand, automated ones can be done again easily with only a few clicks. This automation releases important human resources, letting testers concentrate on more inventive and explorative parts of testing like edge cases and how to use.
**Increased test coverage**
Manual testing for regression often fails to cover all tests completely because there is not enough time or people. But, automated testing for the same does many more test cases quickly than a person could do. It allows for complete testing of different situations, like edge cases and boundary conditions, which improves the total quality of the software.
**Early detection of defects**
Running automated tests often helps to find problems early when included in the process of making software. Developers can notice these regressions quickly, usually before they become big problems in the final product. Detecting problems early helps to lower the amount of money and work needed for repairs and lessens negative effects on users, which makes customers more satisfied.
**Regression test suite reusability**
After being made, automated regression test suites can be used again for various versions of the software or future releases. This reuse means there is no need to make new test cases every time, which saves time and keeps testing consistent. Also, automated tests can be useful for checking previous work in new projects, helping to improve efficiency over time.
**Consistent and reliable results**
When teams do manual testing, there is always a chance of making mistakes which can make the test outcomes not consistent. However, when they use automated regression testing, it removes this chance because it runs the tests exactly how they are planned every single time. This uniformity makes sure the outcomes of tests are dependable and can be replicated, which allows programmers to make choices that are well-informed due to precise information.
**Cost reduction**
Starting automated regression testing needs some investment at first, but the advantages in the long run are much more than what it costs. It makes the testing simpler, cuts down manual work and finds problems sooner, which saves money in all the stages of developing software. Additionally, the ability to scale up automated testing helps companies manage bigger and more complicated projects without a corresponding rise in costs for testing.
**Conclusion**
In the fast paced world of software development, it is essential to test well and quickly. Automated regression testing is a big change; it makes tests smoother and help in delivering software products that are of great quality. However, not all automated testing solutions are created equal.
Opkey is a transformative platform that changes how regression testing is done. Opkey has this feature where you can make tests without writing code, so all those who don’t have much technical knowledge can easily switch from doing manual tests to using automated ones with only one click. The drag-and-drop interface is designed so that all workers can easily help with the testing work, even if they do not have much technical experience.
However, there is more, Opkey has a collection of pre-made test accelerators that include over 30,000 automation test situations for more than 12 ERPs. This increases your regression testing range immediately starting from the first day. Furthermore, the report on how changes will influence business processes gives useful information about updates in the ERP system. It suggests and arranges which regression test cases should be done first for the best effectiveness.
Opkey’s technology for self-fixing scripts improves test maintenance by finding and repairing tests that don’t work anymore with only one click, which cuts down the time spent on upkeep by more than 80%. This makes both developing and testing faster, while also helping to keep tests strong and dependable as time goes on.
Additionally, Opkey’s complete testing functions make certain that every connection and special adjustment in ERP systems works perfectly following any change, update or new version of the application. This allows to develop and transform business with assurance that quality is maintained. | rohitbhandari102 |

1,918,163 | Bridging Buyers and Sellers: The Role of Market-Making Bots | Imagine you're at a bustling farmers' market, and there are stalls everywhere. Now, think of each... | 0 | 2024-07-10T06:59:27 | https://dev.to/elena_marie_dad5c9d5d5706/bridging-buyers-and-sellers-the-role-of-market-making-bots-27kj | marketmakingbot, cryptomarketmakingbot |
Imagine you're at a bustling farmers' market, and there are stalls everywhere. Now, think of each stall as a cryptocurrency exchange, and the fruits and vegetables are different cryptocurrencies like Bitcoin, Ethereum, and so on.
A **market-making bot** that will be developed by Crypto Market Making Bot Development Company is like a super-smart stall owner who knows how to keep the market lively and balanced. Its main job is to buy and sell crypto at just the right times to make sure there's always enough supply and demand, which helps keep prices stable.
In **[Market Making Bot Development](https://www.clarisco.com/crypto-market-making-bot-development)**, developers focus on building bots that can place two kinds of orders on the exchange – bid orders (buy orders) and ask orders (sell orders).
Here’s how it works: The bot places two kinds of orders on the exchange – bid orders (buy orders) and ask orders (sell orders). Think of bid orders as the bot saying, “I’ll buy apples for $1 each,” and ask orders as “I’ll sell apples for $1.10 each.” The bot does this for many different cryptos at once, constantly adjusting its prices based on market conditions.
The cool thing about these bots is their speed and efficiency. They can analyze massive amounts of market data in real time, something that would be impossible for a human to do. They look at things like current prices, trading volumes, and order books to decide the best prices to buy and sell.
The goal of the market-making bot is to make small profits on the difference between the buy and sell prices, known as the spread. So, if the bot buys Bitcoin for $30,000 and sells it for $30,100, it makes a $100 profit. By doing this hundreds or thousands of times a day, those small profits add up.
But it’s not just about making money. These bots also play a crucial role in keeping the market liquid. Liquidity means there are always enough buyers and sellers, so trades can happen quickly without causing big price changes. This is super important because it makes trading smoother and more reliable for everyone.
Of course, running a market-making bot isn’t without its challenges. Because of its extreme volatility, prices in the cryptocurrency market can fluctuate greatly. The bot has to be smart enough to adapt to sudden changes and avoid getting caught in large price drops or spikes. Plus, it needs to manage risks like slippage (when prices change before an order is filled) and market manipulation.
**[Crypto Market Maker Bot Development](https://www.clarisco.com/crypto-market-making-bot-development)** is an evolving concept nowadays. In a nutshell, a Crypto Market Making Bot is like a tireless, super-smart trader that helps keep the market moving smoothly while making small profits along the way.

Property-based testing is a powerful testing methodology that allows developers to automatically generate and test a wide range of input data against specified properties of the software under test. Unlike traditional example-based testing, which uses specific, predefined inputs, [property based testing](https://keploy.io/blog/technology/automated-end-to-end-tests-using-property-based-testing-part-i) explores the entire input space to uncover edge cases and potential bugs. This article explores the concept of property-based testing, its advantages, popular frameworks, and best practices for effectively implementing it in your software development process.
Understanding Property-Based Testing
Property-based testing involves defining properties that the software should satisfy for all possible inputs. These properties are often invariants, which are conditions that should always hold true regardless of the input. The testing framework then generates a large number of random inputs and checks if the properties hold for each input.
For example, consider a function that reverses a list. A property for this function could be that reversing the list twice should return the original list. Property-based testing would involve generating numerous random lists, reversing each one twice, and verifying that the result matches the original list.
Advantages of Property-Based Testing
1. Comprehensive Coverage: Property-based testing explores a wide range of input scenarios, including edge cases that might be overlooked in traditional testing.
2. Automated Test Generation: The testing framework automatically generates test cases, reducing the time and effort required to write individual tests.
3. Early Bug Detection: By testing a broad spectrum of inputs, property-based testing can uncover bugs and edge cases early in the development process.
4. Documentation of Invariants: Defining properties serves as a form of documentation, clearly stating the expected behavior and invariants of the software.
5. Scalability: Property-based testing scales well with complex input spaces, making it suitable for testing algorithms, data structures, and other intricate code.
Popular Property-Based Testing Frameworks
QuickCheck (Haskell)
QuickCheck is the pioneering property-based testing framework, originally developed for Haskell. It has inspired many similar frameworks in other programming languages.
• Features:
o Generates random test cases based on specified properties.
o Shrinks failing test cases to minimal examples for easier debugging.
o Highly customizable with support for user-defined generators.
• Example:
haskell
Copy code
import Test.QuickCheck
-- Property: Reversing a list twice should return the original list
prop_reverseTwice :: [Int] -> Bool
prop_reverseTwice xs = reverse (reverse xs) == xs
main :: IO ()
main = quickCheck prop_reverseTwice
Hypothesis (Python)
Hypothesis is a property-based testing framework for Python, providing powerful features and ease of use.
• Features:
o Generates and shrinks test cases automatically.
o Integrates seamlessly with existing testing frameworks like pytest.
o Supports complex data generation with a rich set of built-in strategies.
• Example:
python
Copy code
from hypothesis import given, strategies as st
# Property: Reversing a list twice should return the original list
@given(st.lists(st.integers()))
def test_reverse_twice(xs):
assert xs == list(reversed(list(reversed(xs))))
if __name__ == "__main__":
import pytest
pytest.main()
ScalaCheck (Scala)
ScalaCheck is a property-based testing framework for Scala, inspired by QuickCheck.
• Features:
o Generates random test cases and shrinks failing cases.
o Integrates with ScalaTest and specs2.
o Provides a rich set of generators for common data types.
• Example:
scala
Copy code
import org.scalacheck.Prop.forAll
import org.scalacheck.Properties
object ListSpecification extends Properties("List") {
// Property: Reversing a list twice should return the original list
property("reverseTwice") = forAll { xs: List[Int] =>
xs.reverse.reverse == xs
}
}
Best Practices for Property-Based Testing
1. Identify Key Properties: Focus on properties that capture the essential behavior and invariants of the software. These properties should be general and apply to a wide range of inputs.
2. Start Simple: Begin with simple properties and gradually introduce more complex properties as you gain confidence in the framework and the software under test.
3. Use Built-in Generators: Leverage the built-in data generators provided by the framework. These generators can produce a wide variety of inputs, including edge cases.
4. Custom Generators: For complex data types or specific testing needs, create custom generators to produce the desired input data.
5. Shrinking: Take advantage of the shrinking feature provided by the framework. Shrinking helps minimize failing test cases, making it easier to identify and fix the underlying issues.
6. Integrate with CI/CD: Integrate property-based tests into your continuous integration and continuous deployment (CI/CD) pipeline to ensure that they run automatically and catch issues early.
7. Combine with Example-Based Testing: Use property-based testing alongside example-based testing. Example-based tests are useful for specific scenarios and known edge cases, while property-based tests explore a broader input space.
8. Review and Refactor: Regularly review and refactor your properties and generators to ensure they remain relevant and effective as the software evolves.
Example of Property-Based Testing in Practice
Consider a function that calculates the sum of all integers in a list. We can define a property that the sum of a list should be equal to the sum of its parts when divided into two sublists.
Python Example with Hypothesis
python
Copy code
from hypothesis import given, strategies as st
def sum_list(lst):
return sum(lst)
@given(st.lists(st.integers()))
def test_sum_sublists(lst):
# Split the list into two sublists
n = len(lst) // 2
sublist1 = lst[:n]
sublist2 = lst[n:]
# Property: The sum of the entire list should be equal to the sum of the sublists
assert sum_list(lst) == sum_list(sublist1) + sum_list(sublist2)
if __name__ == "__main__":
import pytest
pytest.main()
This example uses Hypothesis to generate random lists of integers and verifies that the sum of the entire list equals the sum of its parts when divided into two sublists.
Conclusion
Property-based testing is a robust and versatile testing methodology that complements traditional example-based testing. By defining properties and automatically generating a wide range of test cases, property-based testing helps ensure comprehensive coverage and early detection of edge cases and bugs. Leveraging frameworks like QuickCheck, Hypothesis, and ScalaCheck, developers can implement property-based testing effectively and enhance the quality and reliability of their software.
