java - 如何修复 "No ModelAndView found"失败的测试？

Question

这个类在我的测试层次结构的顶部:

@TestPropertySource("/test.properties")
@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest
public abstract class ApplicationAbstractTest {
}

还有一些测试类:

@WebAppConfiguration
@ActiveProfiles("mysql")
abstract public class AbstractControllerTest extends ApplicationAbstractTest {

    protected MockMvc mockMvc;

    @Autowired
    private WebApplicationContext webApplicationContext;

    @PostConstruct
    private void postConstruct() {
        mockMvc = MockMvcBuilders
                .webAppContextSetup(webApplicationContext)
                .apply(springSecurity())
                .build();
    }
}

JsonUserServiceTest:

@ActiveProfiles("json")
public class JsonUserServiceTest extends ApplicationAbstractTest {
    @Before
    public void setUp() throws Exception {
        ...
    }
}

接触 Controller 测试:

public class ContactControllerTest extends AbstractControllerTest {
    @Test
    public void testGet() throws Exception {
        mockMvc.perform(get("/update-" + ID + "-contact")
                .with(userAuth(USER)))
//                .andExpect(status().isOk())
                .andDo(print())
                .andExpect(view().name("details"))
                .andExpect(forwardedUrl("/WEB-INF/jsp/details.jsp"));
    }
}

因此，当我一起运行 ContactControllerTest 时 - 它是成功的，并且 print 方法向我显示:

Handler:
             Type = com.telecom.web.ContactController
           Method = public java.lang.String com.myApp.web.ContactController.details(java.lang.Integer,org.springframework.ui.ModelMap)

但是当我运行所有测试时，JsonUserServiceTest 首先运行，ContactControllerTest 失败。 print 显示:

Handler:
             Type = null
...
java.lang.AssertionError: No ModelAndView found

配置有什么问题？或者如何排除故障？

更新:同时，这样测试，总是可以正常工作:

public class UserControllerTest extends AbstractControllerTest {
    @Test
    public void testRegister() throws Exception {
        mockMvc.perform(get("/register"))
                .andDo(print())
                .andExpect(view().name("profile"))
                .andExpect(forwardedUrl("/WEB-INF/jsp/profile.jsp"));
    }
}

更新:我正在测试 Controller 的方法:

@GetMapping("/update-{id}-contact")
public String details(@PathVariable Integer id, ModelMap model) {
    Integer userId = AuthorizedUser.id();
    LOG.info("get contact {} for User {}", id, userId);
    Contact contact = service.get(id, userId);
    model.addAttribute("contact", contact);
    return "details";
}

我也有这样的bean:

@Bean
public InternalResourceViewResolver viewResolver() {
    InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
    viewResolver.setViewClass(JstlView.class);
    viewResolver.setPrefix("/WEB-INF/jsp/");
    viewResolver.setSuffix(".jsp");

    return viewResolver;
}

UPD:我尝试在单独的类中配置 mockMvc:

@Configuration
public class TestConfig {

    @Autowired
    private WebApplicationContext webApplicationContext;

    @Bean
    public MockMvc mockMvc() {
        return MockMvcBuilders
                .webAppContextSetup(webApplicationContext)
                .apply(springSecurity())
                .build();
    }
}

并在此处添加:

@WebAppConfiguration
@ContextConfiguration(classes = {TestConfig.class})
@ActiveProfiles("mysql")
abstract public class AbstractControllerTest extends ApplicationAbstractTest {

但我收到了:

java.lang.IllegalStateException: springSecurityFilterChain cannot be null. Ensure a Bean with the name springSecurityFilterChain implementing Filter is present or inject the Filter to be used.

Answer 1

WARN 消息不会导致测试用例失败。它只是说实体管理器工厂被注册了两次。如果您使用相同的 Entity Manager Factory 集群您的应用程序，这只会是一个问题。对于测试用例运行，这不是一个值得关注的问题。

测试用例失败的根本原因就在这两行

 .andExpect(view().name("details"))
 .andExpect(forwardedUrl("/WEB-INF/jsp/details.jsp"));

请检查项目是否有名为“details”的 View ，转发的url为“/WEB-INF/jsp/details.jsp”

更新

你能试试这个吗

@Configuration
public class TestConfig {


@Autowired
private Filter springSecurityFilterChain;

@Autowired
private WebApplicationContext webApplicationContext;

@Bean
public MockMvc mockMvc() {
    return MockMvcBuilders
            .webAppContextSetup(webApplicationContext)
            .apply(springSecurityFilterChain)
            .build();
}
}
