Found that the tests at the RetryNeedsMultipleServices test case on file test_keep_client.py are using assertTrue to compare values instead of assertEqual. For example:

    def test_success_after_exception(self):
        with tutil.mock_keep_responses(
                'acbd18db4cc2f85cedef654fccc4a4d8+3',
                Exception('mock err'), 200, 200) as req_mock:
            self.keep_client.put('foo', num_retries=1, copies=2)
        self.assertTrue(3, req_mock.call_count)
