The environment configuration for these tests comes from two different sources: environment variables and an encrypted secrets file.
## Environment Variables
Most non-sensitive runtime configuration comes from environment variables. All of our environment variables have fallback defaults.
For example:
```
VIEWPORT_NAME=mobile yarn jest specs/
```
The list of supported environment variables are found in [`env-variables.ts`](../../../packages/calypso-e2e//src/env-variables.ts). This file also adds static type checking and is the most up-to-date resource. The [Environment Variables](./environment_variables.md) page may be out of date but will contain explanations of what the individual variables mean.
To use:
```typescript
import { envVariables } from '@automattic/calypso-e2e';
// Later
if ( envVariables.VIEWPORT_NAME === 'mobile' ) {
// Do x ;
}
```
## Secrets File
### Decrypting the Secrets
Within `@automattic/calypso-e2e/src/secrets` is an encrypted file that holds various sensitive secrets, such as API keys and test account information. This must be decrypted prior to use.
**Automatticians**: please refer to the Field Guide page - PCYsg-vnR-p2 for more information.
**Trialmatticians**: please contact a team member in your Slack chat for the decryption key.
First set the environment variable `E2E_SECRETS_KEY` to the "Calypso E2E Config decode key" from the Automattic secret store.
```bash
export E2E_SECRETS_KEY=''
```
Then run the following command to decrypt the secrets:
```bash
# If within test/e2e directory
yarn decrypt-secrets
# If at repo root
yarn workspace wp-e2e-tests decrypt-secrets
```
The decrypted file must **NEVER be committed.** There are `.gitignore` rules to protect against this, but be vigilant nonetheless!
### Using the Secrets
The secrets are read and validated at runtime. They are accessed through the [`SecretsManager`](../../../packages/calypso-e2e/src/secrets/secrets-manager.ts) static class, which presents the secrets with static typings.
To use:
```typescript
import { SecretsManager } from '@automattic/calypso-e2e';
// Later in the spec
const credentials = SecretsManager.secrets.testAccounts.;
```
