pytest.mark.raises

✓ pytest.mark.raises (no import needed)

The marker is registered automatically via plugin; no explicit import required.

Use @pytest.mark.raises to assert an exception is raised.

@pytest.mark.raises(ValueError, match='invalid') def test_raises(): raise ValueError('invalid value')

Debug

Known issues

deprecatedpytest-raises is no longer actively maintained. Prefer `pytest.raises` context manager or other mechanisms.

fix

Rewrite using `with pytest.raises(ValueError): ...`

affects: all

gotcha`@pytest.mark.raises` cannot use `pytest.param` or parametrization with the raises marker directly. The marker is applied to the whole function, not per-parametrization.

fix

Use `pytest.raises` inside a parametrized test function.

affects: all

gotchaIf the test function does not raise the expected exception, the test fails with a custom error message from the plugin, not the usual `Failed: DID NOT RAISE` format. This can confuse CI log parsers.

fix

Switch to built-in `pytest.raises` for consistent error messages.

affects: all
