I try to run a unit test, in a yaml file for possible values in a config file I have changed flashing: single|enum(off,all,match,mask,not_set)|not_set to flashing: single|enum(off,all,match,mask,not_set)|off no code change, no nothing else. Before the change the unit test run fine, now it throws an error: Traceback (most recent call last): File "C:\Users\d\AppData\Local\Programs\Python\Python312\Lib\unittest\mock.py", line 1396, in patched return func(*newargs, **newkeywargs) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\d\mpfenv2\Lib\site-packages\mpf\tests\test_SegmentDisplay.py", line 1126, in test_transitions_with_player mock_set_text.assert_has_calls([ File "C:\Users\d\AppData\Local\Programs\Python\Python312\Lib\unittest\mock.py", line 986, in assert_has_calls raise AssertionError( AssertionError: Calls not found.

It is only a gut feeling that this is related, might be on the wrong path. Any hint into what direction I can investigate how to fix the issue? Continue reading...
