How to Automatically re-run our TDD tests when changing a file

In this episode I will show you a very quick way to use Grunt to automate the running and re-running of our PHPUnit / Codeception unit test suite whenever you alter / save / update a file.

This is cool as it means you can constantly monitor the progress of your code changes without having to periodically interrupt your workflow as you re-run your test suite. Ultimately, the less friction involved in running your tests, the more likely you are to run and use them, and the better your code will become.
