Content
The attached patch adds two helper methods to `unittest.TestCase`: `assertIsSubclass` and `assertIsNotSubclass`. These methods are similar to the `assertIsInstance` and `assertIsNotInstance` methods that are already part of `unittest.TestCase`. They allow one to test if a class is a subclass of another class using the `issubclass` builtin. These methods can be used like: self.assertIsSubclass(cls, parent_cls) These new methods provide a nicer error message and more consistent interface over the alternatives: self.assertTrue(issubclass(cls, parent_cls)) assert issubclass(cls, parent_cls)
