如何为websocket编写TestCase？

Question

我只想在setUp和tearDown中为WebSocketClientProtocol写一个TestCase，我想我正确设置了Server。

我想要的只是test client connected to server and server send some message client will receive此而已。

以下是我尝试制作的代码，但从这里开始我不会做得更深

class WebSocketTest(unittest.TestCase):

    def setUp(self):
        factory = WebSocketServerFactory("ws://localhost:8000")
        self.listening_port = listenWS(factory)
        self.factory, self.port = factory, port

    def tearDown(self):
        self.listening_port.stopListening()

    def test_client_message(self):
        client_factory = TestClientProtocolFactory(
            url="ws://127.0.0.1:8000".format(self.port))
        connectWS(client_factory)
