Inherit markers from generate_test_description #670

Closed cottsay closed 1 year ago

cottsay commented 1 year ago

As it stands, pytest sees launch tests as a single testing node with no markings. It would be useful if normal pytest markings could be used on the generate_test_description function (where @pytest.mark.launch_test and @launch_testing.parametrize are currently specified).

Notably, this will always mark the test nodes with 'launch_test', and will allow the use of very useful marking like 'xfail', 'skip', and 'skipif'.

To duplicate the markers from the entrypoint, this change makes use of the MarkerGenerator singleton (aka pytest.mark) to create a new MarkerDecorator with the same name, then copies the original marker's arguments, which are critical for markers like skipif.

Complements ros2/launch_ros#330
