Spring jmsTemplate send Unit testing doen't work

My service method looks like below, I am trying to mock JmsTemplate so that it can send message during unit testing, but it doesn't execute jmsTemplate.send(...), it directly goes to next line, How can i execute jmsTemplate.send(..) part of code of my service class using unit testing?

public int invokeCallbackListener(final MyObject payload, final MyTask task) throws Exception{
        //create map of payload and taskId
        int taskStatusCd = task.getTaskSatus().getCode();
        final Map<String, Object> map = new HashMap<String, Object>();
        map.put(PAYLOAD_KEY, payload);
        map.put(TASK_ID_KEY, task.getTaskId());

        //generate JMSCorrelationID
        final String correlationId = UUID.randomUUID().toString();

        String requestQueue = System.getProperty("REQUEST_QUEUE");
        requestQueue = requestQueue!=null?requestQueue:ExportConstants.DEFAULT_REQUEST_QUEUE;
        jmsTemplate.send(requestQueue, new MessageCreator() {           
            @Override
            public Message createMessage(Session session) throws JMSException {
                ObjectMessage message = session.createObjectMessage((Serializable)map);
                message.setJMSCorrelationID(correlationId);
                message.setStringProperty(MESSAGE_TYPE_PROPERTY,payload.getMessageType().getMessageType());             
                return message;
            }           
        });
        l.info("Request Message sent with correlationID: " + correlationId);

        taskStatusCd = waitForResponseStatus(task.TaskId(), taskStatusCd, correlationId);
        return taskStatusCd;
    }

This is my test class code.

RemoteInvocationService remoteInvocationService;
    JmsTemplate mockTemplate;
    Session mockSession;
    Queue mockQueue;
    ObjectMessage mockMessage;
    MessageCreator mockmessageCreator;
    @Before
    public void setUp() throws Exception {
        remoteInvocationService = new RemoteInvocationService();
         mockTemplate = mock(JmsTemplate.class);
         mockSession = mock(Session.class);
         mockQueue = mock(Queue.class);
         mockMessage = mock(ObjectMessage.class);
         mockmessageCreator = mock(MessageCreator.class);
         when(mockSession.createObjectMessage()).thenReturn(mockMessage);
         when(mockQueue.toString()).thenReturn("testQueue");

         Mockito.doAnswer(new Answer<Message>() { 
             @Override 
             public Message answer(final InvocationOnMock invocation) throws JMSException { 
                final Object[] args = invocation.getArguments(); 
                final MessageCreator arg = (MessageCreator)args[0];
                return arg.createMessage(mockSession); 
             } 
         }).when(mockTemplate).send(Mockito.any(MessageCreator.class)); 



            mockTemplate.setDefaultDestination(mockQueue);
            remoteInvocationService.setJmsTemplate(mockTemplate);
    }


    @Test
    public void testMessage() throws Exception{
        MyTask task = new MyTask();
        task.setTaskSatus(Status.Pending);

        remoteInvocationService.invokeCallbackListener(new MyObject(), task); 


    }
