numpy.testing.dec.knownfailureif

testing.dec.knownfailureif(fail_condition, msg=None)

Make function raise KnownFailureException 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_conditionbool or callable

Flag to determine whether to mark the decorated test as a known failure (if True) or not (if False).

msgstr, optional

Message to give on raising a KnownFailureException exception. Default is None.

Returns

decoratorfunction

Decorator, which, when applied to a function, causes KnownFailureException to be raised when fail_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.
