What is strange is that if I remove the self.redis_factory.client.transport.loseConnection() in the tearDown method, the test is OK, but of course I get an error because the reactor was unclean: gateway.test.test_example GatewayServiceTestCase test_messageReceived ... [OK] [ERROR] =============================================================================== [ERROR] Traceback (most recent call last): Failure: twisted.trial.util.DirtyReactorAggregateError: Reactor was unclean.
