我在验证一个被模仿的方法( fileSenderService.sendFile )正好打了两次电话。无论出于何种原因，mockito都不会失败测试，无论预期的调用次数是多少。我是这样用的： verify(mockService, times(expectedNumberOfInvocations)).sendFile(any(String.class), any(byte[].class)); 不管我在times（）方法中使用什么值，测试总是通过的。
myservice如下所示：

@Service
public class MyServiceImpl implements MyService {

    @Autowired
    private FileSenderService fileSenderService;

    public void createAndSendFiles(){
        //doSomeStuff, prepare fileNames and fileContents(byte arrays)
        //execute the sendFile twice
        fileSenderService.sendFile(aFileName, aByteArray); //void method; mocked for testing
        fileSenderService.sendFile(bFileName, bByteArray); //void method; mocked for testing
    }

测试类

@RunWith(SpringRunner.class)
@WebAppConfiguration
@SpringBootTest(classes = {Application.class, FileSenderServiceMock.class})
@ContextConfiguration
public class MyServiceTest{

    @Autowired
    private MyService myService;

    @Autowired
    FileSenderService mock;

    @Test
    public void shouldCreateAndSendFiles(){
        myService.createAndSendFiles(); //inside this method sendFile() is called twice
        verify(mock, times(999)).sendFile(any(String.class), any(byte[].class)); //THE PROBLEM - why times(999) does not fail the test?
    }
}

filesenderservice及其模拟：

@Service
public class FileSenderServiceImpl implements FileSenderService {
   @Override
    public void sendFile(String name, byte [] content) {
      //send the file
    }
}

//used for testing instead of the actual FileSenderServiceImpl 
public class FileSenderServiceMock {
    @Bean
    @Primary
    public FileSenderService getFileSenderServiceMock(){
        FileSenderServicemock = Mockito.mock(FileSenderService.class, Mockito.RETURNS_DEEP_STUBS);

        doNothing().when(mock).sendFile(isA(String.class), isA(byte[].class));
        return mock;
    }
