[TIP] parametrize a pytest finalizer

[Bruno Oliveira]

Hi Chris,

You can use a lambda function:

@pytest.fixture()
def test_fixture(request):

    def cleanup(cleanup_parameter):
        print cleanup_parameter

    try:
        raise
    except Exception:
        cleanup("Problem in fixture!")

    request.addfinalizer(lambda: cleanup("Cleaning up"))

Make sure to run the above using "-s" so no output is captured by pytest.

Hope this helps,

Best Regards,
