 # Running tests
 
-FreshRSS is tested with [PHPUnit](https://phpunit.de/). No code should be merged in `edge` if the tests don’t pass.
+FreshRSS is tested with [PHPUnit](https://phpunit.de/), [PHPStan](https://phpstan.org/), [PHP\_CodeSniffer](https://github.com/PHPCSStandards/PHP_CodeSniffer/), and more.
+No code should be merged in `edge` if the tests don’t pass.
 
 ## Locally
 
 As a developer, you can run the test suite on your PC easily with `make` commands. You can run the test suite with:
 
 ```sh
-make test
+cd ./FreshRSS/
+make test-all
 ```
 
-This command downloads the PHPUnit binary and verifies its checksum. If the verification fails, the file is deleted. In this case, you should [open an issue on GitHub](https://github.com/FreshRSS/FreshRSS/issues/new) to let maintainers know about the problem.
-
-Then, it executes PHPUnit in a Docker container. If you don’t use Docker, you can run the command directly with:
+Some syntax, formatting, whitespace, and i18n conventions can be fixed automatically with:
 
 ```sh
-NO_DOCKER=true make test
+make fix-all
 ```
 
-The linter can be run with a `make` command as well:
+Some tests can run inside some Docker images, in particular to test against minimum and maximum versions of PHP:
 
 ```sh
-make lint # to execute the linter on the PHP files
-make lint-fix # or, to fix the errors detected by the linter
+# Prepare
+make composer-test
+docker build --pull --tag freshrss/freshrss:oldest -f Docker/Dockerfile-Oldest .
+docker build --pull --tag freshrss/freshrss:newest -f Docker/Dockerfile-Newest .
+
+# Run
+docker run --rm -e FRESHRSS_ENV=development -e TZ=UTC -v $(pwd):/var/www/FreshRSS freshrss/freshrss:oldest bin/composer test
+docker run --rm -e FRESHRSS_ENV=development -e TZ=UTC -v $(pwd):/var/www/FreshRSS freshrss/freshrss:newest bin/composer test
 ```
 
-Similarly to PHPUnit, it downloads a [PHP\_CodeSniffer](https://github.com/squizlabs/PHP_CodeSniffer) binary (i.e. `phpcs` or `phpcbf` depending on the command) and verifies its checksum.

 ## GitHub Actions for Continuous Integration
 
 Tests are automatically run when you open a pull request on GitHub.
