Question

我有以下内容：

控制器类：

@Controller
@RequestMapping("/")
public class MainController {

    @Inject
    @Named("dbDaoService")
    IDaoService dbDaoService;

    @RequestMapping(method = RequestMethod.GET)
    public String init(ModelMap model) {
        List<Tags> tags = dbDaoService.getAllTags();
        model.addAttribute("tags", tags);
        return "create";
    }
}

服务类：

@Service("dbDaoService")
public class DBDaoService implements IDaoService {

    @PersistenceContext(unitName = "MyEntityManager")
    private EntityManager entityManager;

    @Override
    @Transactional
    public List<Tags> getAllTags() {
         if(tags == null) {
            TypedQuery<Tags> query = entityManager.createNamedQuery("Tags.findAll", Tags.class);
            tags = query.getResultList();
        }

        return tags;
    }
}

测试类：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {WebConfig.class})
@WebAppConfiguration
public class MainControllerTest  {

    private MockMvc mockMvc;

    @Autowired
    private WebApplicationContext context;

    @Before
    public void setUp() throws Exception {
        mockMvc = MockMvcBuilders
                .webAppContextSetup(context)
                .build();
    }

    @Test
    public void init() throws Exception {
        Tags tag1 = new Tags("first");
        Tags tag2 = new Tags("second");

        DBDaoService mock = org.mockito.Mockito.mock(DBDaoService.class);
        when(mock.getAllTags()).thenReturn(Arrays.asList(tag1, tag2));

        mockMvc.perform(get("/"))
            .andExpect(status().isOk())
            .andExpect(view().name("create"))
            .andExpect(forwardedUrl("/WEB-INF/views/create.jsp"))
            .andExpect(model().attribute("tags", hasItem(
                    allOf(
                            hasProperty("name", is("first"))
                    )
            )))
            .andExpect(model().attribute("tags", hasItem(
                    allOf(
                            hasProperty("name", is("second"))
                    )
            )));
    }
}

当我运行MainControllerTest时，它失败了，因为它从DBDaoService获得了“Tag”实体（这意味着，来自数据库），但我希望它将使用模拟服务。

怎么了？

当前测试设置加载弹簧配置，并使用WebApplicationContext处理由于MockMvcBuilders.webAppContextSetup(context).build();引起的请求。因此，模拟的bean被忽略，因为它们没有被指示参与。

要交织它们，配置应更新为MockMvcBuilders.standaloneSetup(controller).build()。

示例测试用例应如下所示（注意MainController的附加模拟和MockMvcBuilders.standaloneSetup的配置更新以及通过MockitoAnnotations.initMocks ）

@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(classes = {WebConfig.class}) @WebAppConfiguration public class MainControllerTest { private MockMvc mockMvc; @InjectMocks private MainController controller; @Mock private DBDaoService daoService; @Before public void setUp() throws Exception { MockitoAnnotations.initMocks(this); InternalResourceViewResolver viewResolver = new InternalResourceViewResolver(); viewResolver.setPrefix("/WEB-INF/view/"); viewResolver.setSuffix(".jsp"); mockMvc = MockMvcBuilders.standaloneSetup(controller) .setViewResolvers(viewResolver) .build(); Tags tag1 = new Tags("first"); Tags tag2 = new Tags("second"); when(daoService.getAllTags()).thenReturn(Arrays.asList(tag1, tag2)); } @Test public void init() throws Exception { mockMvc.perform(get("/")) .andExpect(status().isOk()) .andExpect(view().name("create")) .andExpect(forwardedUrl("/WEB-INF/views/create.jsp")) .andExpect(model().attribute("tags", hasItem( allOf( hasProperty("name", is("first")) ) ))) .andExpect(model().attribute("tags", hasItem( allOf( hasProperty("name", is("second")) ) ))); } }

弹簧控制器测试
