| ## Testing configuration | |
| At the moment we maintain four different group of tests. You can find configurations for all of them in the following subfolders: | |
| - `client` - unit and component tests for code located in `client` top level folder. | |
| - `integration` - integration tests for code located in `bin`, `client` and `server` top level folders. | |
| - `server` - unit tests for code located in `server` top level folder. | |
| - `e2e` - automated tests for the entire project. | |
| Check [testing overview](../docs/testing/testing-overview.md) to learn more how all those test configurations are consumed by [Jest](https://facebook.github.io/jest/) testing platform to ensure proper code quality of Calypso codebase. | |
| ## Test helpers | |
| This folder contains also legacy test helpers which were used with the previous testing tool called [Mocha](https://mochajs.org/). They are still used in many places, but should be considered as **deprecated**. Check the corresponding code comments to learn about valid alternatives. | |
