This documentation is for an unreleased version of MPF!
This is the developer documentation for MPF 0.51, which is the “dev” (next) release of MPF that is a work-in-progress. Use the “Read the Docs” link in the lower left corner to view the developer docs for the version of MPF you’re using.
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 800 unit tests for MPF and MPF-MC, each which contain dozens of individual tests.)
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 machine. Read on for details:
