 The tests are run from the project's root (not from the bundle's root: so, do not change the directory to any bundle directory before running tests).

 ```bash
 # Run a specific test file
-vendor/bin/phpunit path/to/TestFile.php
+symfony composer exec phpunit -- path/to/TestFile.php
 
 # Run a specific test method
-vendor/bin/phpunit --filter methodName path/to/TestFile.php
+symfony composer exec phpunit -- --filter methodName path/to/TestFile.php
 ```
