Removing tests is what I did at first, later switched to using the marker.

Thanks for the tip!

In the end I want a report on each test. If a run is aborted out of pytest
control, there is no report available on the already completed tests, since
pytest generates a report when all tests are completed. I would like to
save a report on a test once a test is completed.
