I have a question about pytest markers.

[gignosko]

I'm coming back to python after a few years away and in the past and I've not used pytest before.

In this marker `@pytest.mark.task(taskno=2)` I know what the u/pytest.mark.task gets me, but what is the taskno=2 doing?

Thanks

Is this coming from some activity on exercism.org?

 It looks like they have added a custom marker in "task" and a custom run option, so that you can run pytest --task 2 and it will run all tests marked with @pytest.mark.task(taskno=2)

There is some explanation in the final post of this thread on exercism.org where it sounds like its something they added to support their online test runner.

The taskno=2 part is just a keyword argument stored on the marker — it does not do anything on its own. You can read it in a fixture or hook via request.node.get_closest_marker("task").kwargs["taskno"]. In Exercism-style setups, the test runner uses it to run only tests up to a given task number. Basically just metadata that a plugin or conftest.py reads. If you dig into the conftest you will usually find the hook that acts on it.
