        raised, it will not be caught, and the test case will be
        deemed to have suffered an error, exactly as for an

The context manager keeps a reference to the exception as
        the 'exception' attribute. This allows you to inspect the
        exception after the assertion::

with self.assertRaises(SomeException) as cm:
                do_something()
