**Using with** ``pytest.mark.parametrize``

When using :ref:`pytest.mark.parametrize ref` it is possible to parametrize tests
    such that some runs raise a warning and others do not.

This could be achieved in the same way as with exceptions, see
    :ref:`parametrizing_conditional_raising` for an example.
