Mockito Java doAnswer

Question

這不會編譯。我得到一個UnfinishedStubbingException。我已經閱讀了這個網站上的Mockito api和其他問題，我認爲我的語法不應該是錯誤的，但它在doAnswer(new Answer() {失敗，所以我認爲它必須是錯的，但我不知道在哪裏。謝謝。

doAnswer(new Answer() { 
      @Override 
      public Object answer(InvocationOnMock invocation) throws Throwable { 
       Object[] args = invocation.getArguments(); 
       ((CrestronNioSocketHandler.NioEventReceiver) args[0]).onDataReceived(new byte[wantedNumber]); 
       return null; 
      } 
     }).when(mockedChannel.read(any(ByteBuffer.class))); 

Answer 1

它應該是這樣的

doAnswer(new Answer() { 
      @Override 
      public Object answer(InvocationOnMock invocation) throws Throwable { 
       Object[] args = invocation.getArguments(); 
       ((CrestronNioSocketHandler.NioEventReceiver) args[0]).onDataReceived(new byte[wantedNumber]); 
       return null; 
      } 
     }).when(mockedChannel).read(any(ByteBuffer.class)); 

檢查this question大約有磕碰的Mockito不同的方式。
