Unit testing

If you want to run the unit tests for mass2 go to your mass2 directory and do pytest .

If you want to add tests to mass2, you do not need to use the old unittest framework. Simpler, more modern tests in the pytest style are allowed (and preferred). Put any new tests in a file somewhere inside tests with a name like test_myfeature.py, it must match the pattern test_*.py to be found by pytest.

On each commit to develop, the tests will be run automatically by GitHub Actions. See results of recent tests.
