Spring 弹簧控制器试验
我有以下资料: 控制器类:Spring 弹簧控制器试验,spring,unit-testing,junit,mockito,Spring,Unit Testing,Junit,Mockito,我有以下资料: 控制器类: @Controller @RequestMapping("/") public class MainController { @Inject @Named("dbDaoService") IDaoService dbDaoService; @RequestMapping(method = RequestMethod.GET) public String init(ModelMap model) { List&
@Controller
@RequestMapping("/")
public class MainController {
@Inject

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

)));
}
}
当我运行MainControllerTest
时,它失败了,因为它从DBDaoService
(它的意思是,从数据库)获取“标记”实体,但我希望它将使用模拟服务
怎么了?当前的测试设置加载spring配置,并使用
WebApplicationContext
来处理由于MockMvcBuilders.webAppContextSetup(context.build())而产生的请求代码>。因此,模拟bean被忽略,因为它们没有被指示参与
要将它们交织在一起,应将配置更新为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>使用Mockito注释的说明)
