# numpy.testing.decorators.knownfailureif

`numpy.testing.decorators.``knownfailureif`(fail_condition, msg=None)

  Make function raise KnownFailureTest exception if given condition is true.

  If the condition is a callable, it is used at runtime to dynamically make the decision. This is useful for tests that may require costly imports, to delay the cost until the test suite is actually executed.

  Parameters : | fail_condition : bool or callable Flag to determine whether to mark the decorated test as a known failure (if True) or not (if False). msg : str, optional Message to give on raising a KnownFailureTest exception. Default is None.
  Returns : | decorator : function Decorator, which, when applied to a function, causes SkipTest to be raised when skip_condition is True, and the function to be called normally otherwise.

  Notes

  The decorator itself is decorated with the `nose.tools.make_decorator` function in order to transmit function name, and various other metadata.
