We highly encourage you to execute the unit tests before creating a Pull Request.
Connect into your container and run this command:
IN DOCKER
./psh.phar unit
We know the unit tests take quite a long time.
If you want to just execute tests you have created, simply assign your custom group to your test. Then run the test suite only for the tests of your custom group.
That should be way faster
Don't forget to still run all tests before creating your pull request.
