Question

我对Mockito和使用@Spy注释的字段有点混乱。

我想测试这个课程：

@Service
public class CategoryServiceImpl implements CategoryService {

    @Autowire
    private CategoryRepository categoryRepository;

    private BoundMapperFacade<CategoryDTO, Category> boundMapper;

    @Autowired
    public void createMapper(final Mapper mapper) {

        boundMapper = mapper.getMapperFactory().getMapperFacade(
                CategoryDTO.class, Category.class);
    }

    // Rest of methods...
}

所以，我创建了一个测试类，如下所示：

@RunWith(MockitoJUnitRunner.class)
public class CategoryServiceImplTest {

    @Mock    
    private CategoryRepository categoryRepository;

    @Spy
    private Mapper mapper;

    @Spy
    private BoundMapperFacade<CategoryDTO, Category> boundMapper;

    @InjectMocks
    private CategoryServiceImpl categoryServiceImpl;    

    // Rest of methods...
}

当Mockito实例categoryServiceImpl将categoryRepository注入模拟类但它不知道如何创建boundMapper。这个类依赖于mapper，所以我重写了我的代码：

@RunWith(MockitoJUnitRunner.class)
public class CategoryServiceImplTest {

    @Mock    
    private CategoryRepository categoryRepository;

    @Spy
    private Mapper mapper;

    private BoundMapperFacade<CategoryDTO, Category> boundMapper = spy(mapper.getMapperFactory().getMapperFacade(
                CategoryDTO.class, Category.class));

    @InjectMocks
    private CategoryServiceImpl categoryServiceImpl;    

    // Rest of methods...
}

但现在问题是在Mockito注入mapper之前执行了boundMapper的创建，所以我得到了一个NullPointerException。

那么，有没有办法创建一个依赖于另一个的间谍类，最后在标记为@InjectMocks的字段中注入最后一个？
