      Pytest compatibility class. This implements the simplest level of
      pytest.mark.parametrize for use in nose as an aid in making the transition
      to pytest. It achieves that by adding a dummy var parameter and ignoring
      the doc_func parameter of the base class. It does not support variable
      substitution by name, nor does it support nesting or classes. See the
      pytest documentation for usage.
