I'd like this test to run for anything newer than the "2024.5.0" release (including main). Not sure of the "correct" way to do this.

I think that is correct. pytest.mark.xfail(some_condition, reason="some_reason") which is what this expands to is the canonical way.

@pytest.mark.parametrize("na_position", ["first", "last"])
@pytest.mark.parametrize("ascending", [True, False])
@pytest.mark.parametrize("by", ["a", "b", ["a", "b"]])
