MockMVC로 스프링 MVC 라우터 테스트하기

Question

스프링 테스트로 스프링 MVC 웹 애플리케이션을 테스트하려고한다. 그것은 라우팅을 위해 springmvc-router을 사용하며, 이는 내 routes.conf 파일 대신 @RequestMapping을 사용할 때 제대로 작동하는 테스트를 깨는 것으로 보입니다.

나는 valid.jsp이라고하는 .jsp 파일을 가지고 있으며, Jetty에서 개발 사이트를 실행할 때 정상적으로 표시됩니다. 컨트롤러는 다음과 같습니다

@Controller 
@EnableWebMvc 
public class AuthController { 
    public String valid() { 
    return "valid"; 
    } 
} 

내 routes.conf 파일 GET /valid authController.valid 매핑합니다.

그래서 질문은 : 다음 mockMvc.perform()가 실행되면

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(locations = {"/test-context.xml", 
    "/spring/spring-security.xml", 
    "file:src/main/webapp/WEB-INF/mvc-config.xml"}) 
@WebAppConfiguration 
@Import(RouteConfig.class) 
public class AuthControllerTest { 
    private MockMvc mockMvc; 

    @Autowired 
    private WebApplicationContext webApplicationContext; 

    @Autowired 
    private AuthenticationManager authenticationManager; 

    @Before 
    public void init() { 
    MockitoAnnotations.initMocks(this); 
    mockMvc = 
     MockMvcBuilders.webAppContextSetup(webApplicationContext).dispatchOptions(true).build(); 
    } 

    @Test 
    public void testValid() throws Exception { 
    mockMvc.perform(get("/validation-success")) 
     .andDo(print()) 
     .andExpect(status().isOk()); 
    } 

처럼

지금, 내 테스터는 NullPointerException가 슬로우 보인다는 springmvc와 함께 봄의 테스트 프레임 워크를 사용할 수있다 -라우터?

Answer 1

파기를 한 후 HTTPRequestAdapter.parseRequest() 메서드에 MockMVC가 요청하는 방식에 문제가 있음을 발견했습니다. 특히 MockMVC가 보낸 요청에는 요청에 host이라는 헤더가 포함되지 않습니다.

HTTPRequestAdapter은 헤더가 필요하며 null 일 수 있다는 사실을 고려하지 않으므로 NullPointerException을 생성합니다.

mockMvc.perform(get("/validation-success") 
     .header("host", "localhost:80")) 
     .andExpect(status().isOk()); 

host 헤더가 null되지 않습니다 및 테스트를 통과해야합니다

는이 코드의 문제를 해결했습니다.
