Manually trigger an xpass

I’ve got a large number of dynamically generated tests, and I’d like to be able to trigger an xpass inside the test, just like I can call pytest.fail() and pytest.xfail(). But pytest.xpass() doesn’t seem to exist

an expected failure is to be marked as xfail, the xpass will then automatically happen

fail/xfail raise exceptions, its fundamentally impossible to make a symmetric equivalent for pass/xpass

I’m assuming “known_fails” is known at collect time:

@pytest.mark.parametrize(
    'path',
    [
        pytest.param(
            path, marks=pytest.mark.xfail if path in known_fails else None
        )
        for path in get_valid_files()
    ]
)
def test_valid_file(path):
    ...
