오류가 발생하는 코드

Failed to load ApplicationContext 이 오류가 터짐


@WebMvcTest(UserController.class)
@AutoConfigureRestDocs
@MockBean(JpaMetamodelMappingContext.class)
@DisplayName("유저 컨트롤러 테스트")
class UserControllerTest {

	@MockBean
	private UserService userService;

	@Autowired
	private MockMvc mockMvc;

	@Autowired
	private ObjectMapper objectMapper;

해결 방법1

@AutoConfigureMockMvc(addFilters = false) 이 어노테이션을 추가한다.

그래도 오류가 난다.

JwtAuthenticationFilter에서 사용하는 TokenProvider 를 아무래도 못 찾는 것 같다.

해결

목빈으로 테스트 클래스에 넣어준다.

@MockBean의 역할?


@WebMvcTest(UserController.class)
@AutoConfigureMockMvc(addFilters = false)
@AutoConfigureRestDocs
@MockBean(JpaMetamodelMappingContext.class)
@DisplayName("유저 컨트롤러 테스트")
class UserControllerTest {

	@MockBean
	private JwtAuthenticationFilter jwtAuthenticationFilter;

추가로 알아보기

@WebMvcTest는 MVC 관련된 설정들만 적용한다고 한다. (참조)

@Controller , @ControllerAdvice , @JsonComponent , Converter/GenericConverter , Filter , WebMvcConfigurer ,HandlerMethodArgumentResolver beans but not @Component , @Service or @Repository beans

겁나게 많다..

내가 만든 JwtAuthenticationFilter → OncePerRequestFilter → GenericeFilterBean → Filter

Filter여서 찾아온다.

하지만 Filter에서 사용하는 빈들은 찾아오지 못하는 것 같다.
