Automated TestingΒΆ

The MPF dev team are strong believers in automated testing, and we use a test-driven development (TDD) process for developing MPF itself. (At the time of this writing, there are over 700 unit tests for MPF and MPF-MC, each which test multiple aspects of the codebase.)

We have extended Python's built-in unittest TestCase class for MPF-specific tests, including mocking critical internal elements and adding assertion methods for MPF features.

You can run built-in tests to test MPF itself or extend them if you think you found a bug or if you're adding features to MPF.

We have also built TestCase classes you can use to write unittests for your own game.
