Summary
The documentation for pytest-raises-without-exception (PT010) says:
pytest.raises expects to receive an expected exception as its first argument. If omitted, the pytest.raises call will fail at runtime.
As of pytest 8.4.0 (released June 2, 2025) it is also sufficient to pass the keyword argument match or check. The rule should recognize those arguments too.
