Question

我试图使用Twisted进行简单的集成测试，但我发现了一个我无法处理的错误。

测试的唯一目的是使用callremote进行AMP调用，expect返回true。该测试的代码是开发代码的简化，工作正常。

此行描述了AMP呼叫。

class SendMsg(amp.Command):

    arguments = [('sMsg', amp.String()),('iTimestamp', amp.Integer())]
    response = [('bResult', amp.Boolean())]
    errors = {SlotErrorNotification: 'SLOT_ERROR_NOTIFICATION'}

我还在一个名为SATNETServer的类中描述了该协议

class SATNETServer(amp.AMP):

    def vSendMsg(self, sMsg, iTimestamp):
        return {'bResult': True}
    SendMsg.responder(vSendMsg)

为了建立沟通，我有一个模拟运输的对象。

class FakeTransport(object):

    def write(self, data):
        self.peer.dataReceived(data)

    def loseConnection(self):
        pass

    def getPeer(self):
        pass

    def getHost(self):
        pass

班级考试负责。

class ClientToServerTest(unittest.TestCase):

    def mock_processframe(self, AMP_self, frame):

        CONNECTION_INFO = {}
        gsi = object

        clientprotocol = ClientProtocol(CONNECTION_INFO, gsi)
        clientprotocol.callRemote = mock.MagicMock(side_effect=self.mock_callremote)
    clientprotocol._processframe(frame)


def mock_callremote(self, SendMsg, sMsg, iTimestamp):
    try:
        self.amp.callRemote(SendMsg, sMsg='hola', iTimestamp=misc.get_utc_timestamp())
    except Exception as e:
        log.err(e)

def setUp(self):       
    log.startLogging(sys.stdout)
    log.msg("")

    server = SATNETServer()
    self.amp = AMP()

    server.makeConnection(FakeTransport())
    self.amp.makeConnection(FakeTransport())

    server.transport.peer = self.amp
    self.amp.transport.peer = server

    return True

def test_AMPPresentCorrectFrame(self):
    frame = 'Frame'
    CONNECTION_INFO = {}
    GS = 'Vigo'

    self.amp._processframe = mock.MagicMock(side_effect=self.mock_processframe)

    gsi = GroundStationInterface(CONNECTION_INFO, GS, self.amp)._manageFrame(frame)

运行上述代码时出现的错误如下：

我搜索了文档，我找不到任何可以解释可能发生的事情。我将不胜感激任何帮助。
