So far, if you wanted a test to use a fixture, you put it in the parameter list. You can also mark a test or a class with @pytest.mark.usefixtures(’fixture1’, ’fixture2’). usefixtures takes a string that is composed of a comma-separated list of fixtures to use. It doesn’t make sense to do this with test functions—it’s just more typing. But it does work well for test classes:

        """Test using a class scope fixture."""
