More official way to leave browser window open upon failure?

Question

My coworker Chris came up with this, and it works, but I wonder if there's a more "official" way to do this using unittest.TestCase in Python.

def tearDown(self):
    """ clean up by closing the browser window """
    if sys.exc_info() == (None, None, None):  # leave window open on fail
        self.driver.quit()

I don't know if this will work for pyunit but in Robot Framework, you can access singletons which represent the test suite and test case during the run. May be the unittest runner you are using provides the same functionality instead of having to inspect the stack.
