NotAMockException while Mockito.verify(Object,VerificationMode.atleast(2))

I am using mockito for mock the unit test cases and am getting the following exception

org.mockito.exceptions.misusing.NotAMockException: 
Argument passed to verify() is of type ConsumerImpl and is not a mock!
Make sure you place the parenthesis correctly!
See the examples of correct verifications:
    verify(mock).someMethod();
    verify(mock, times(10)).someMethod();
    verify(mock, atLeastOnce()).someMetenter code herehod();

and my code is

 MessageConsumer mConsumer = Mockito.mock(MessageConsumer.class);
            String data = "new Message for Testing";
            Message message = new Message(data.getBytes());
            Mockito.when(mConsumer.next(10, TimeUnit.SECONDS)).thenReturn(message);
            StringParserTest parserTest = new StringParserTest();
            ConsumerImpl<String> consumer = new ConsumerImpl<String>(mConsumer, parserTest);
            String mes=Mockito.verify(consumer,VerificationModeFactory.times(3)).consumeMessage(10,TimeUnit.SECONDS);

Please some one help me to solve this problem

Thanks in Advance
