Mockito:如何用Mocking测试我的服务?

CorrectionService类的简化版本(为了简单起见删除了可见性修饰符)。

class CorrectionService {

   AddressDao addressDao;

   CorrectionService(AddressDao addressDao) {
       this.addressDao;
   }

   void correctPerson(Long personId) {
       //Do some stuff with the addressDao here...
   }

}

在你的测试中:

import static org.mockito.Mockito.*;

public class CorrectionServiceTest {

    @Before
    public void setUp() {
        addressDao = mock(AddressDao.class);
        correctionService = new CorrectionService(addressDao);
    }


    @Test
    public void shouldCallDeleteAddress() {
        correctionService.correct(VALID_ID);
        verify(addressDao).deleteAddress(VALID_ID);
    }
}  

清洗器版本:

@RunWith(MockitoJUnitRunner.class)
public class CorrectionServiceTest {

    private static final Long VALID_ID = 123L;

    @Mock
    AddressDao addressDao;

    @InjectMocks
    private CorrectionService correctionService;

    @Test
    public void shouldCallDeleteAddress() { 
        //when
        correctionService.correct(VALID_ID);
        //then
        verify(addressDao).deleteAddress(VALID_ID);
    }
}
