我已经阅读过各种关于模拟和测试中存根的文章,包括Martin Fowler的Mocks Are Not Stubs,但仍然不明白其中的区别.

我按照@hoaz的建议.但是,我得到了nullpointer异常

@RunWith(MockitoJUnitRunner.class)
public class GeneralConfigServiceImplTest  {

@InjectMocks private GeneralConfigService generalConfigService;
@Mock private SomeDao someDao;
@Mock private ExternalDependencyClass externalDependencyObject 

@Test
public void testAddGeneralConfigCallDAOSuccess() {
    when(someDao.findMe(any(String.Class))).thenReturn(new ArrayList<String>(Arrays.asList("1234")));

    //println works here, I am able to get collection from my mocked DAO

    // Calling the actual service function
    generalConfigService.process(externalDependencyObject)
    }
}

在我的代码中它是这样的:

import com.xyz.ExternalDependencyClass;

public class  GeneralConfigService{

private SomeDao someDao;

public void process(ExternalDependencyClass externalDependencyObject){

// function using Mockito 
Collection<String> result = someDao.findMe(externalDependencyObject.getId.toString())
    }
}

我也注意到DAO是null所以我做了这个(只是提到,我做了下面的步骤尝试,我知道springUnit和Mockito或xyz之间的区别):

@Autowired
private SomeDao someDao;

@Test
public void …
