Spring Security 적용 시 controller @WebMvcTest

안녕하세요 강사님 좋은 강의를 듣고 공부하면서 실무에 적용시키고 있는 중에 두 가지 문제를 만났는데 구글링으로 해결점이 보이지 않아서 강의 내용과 관련 없지만 힌트라도 얻고자 글을 남기게 되었습니다

Spring boot 3.x 이상 버전이고, Spring security가 적용된 프로젝트입니다

1. 첫 번째 문제는 controller 레이어에서 @WebMvcTest를 적용 시에 검증하고자 하는 controller와 주입받은 빈 객체 이외의 뜬금없는 객체 주입 error가 발생하고 있습니다

@V1RestController
@RequiredArgsConstructor
public class CommonController {

	private final CommonService commonService;
	private static final Logger log = LoggerFactory.getLogger(CommonController.class);

	@GetMapping("/term")
	public ResponseEntity<TermResDto> getTerm(@RequestParam("account_id") Long id) {
		return ResponseEntity.ok(commonService.getTerm(id));
	}

	@GetMapping("/message")
	public ResponseEntity<List<UserMessageResDto>> getUserMessageList(@RequestParam("user_id") Long userId) {
		return ResponseEntity.ok(commonService.getUserMessageList(userId));
	}

	@GetMapping("/notice")
	public ResponseEntity<List<UserNoticeResDto>> getUserNoticeList(@RequestParam("user_id") Long userId) {
		return ResponseEntity.ok(commonService.getNoticeList(userId));
	}
}

class CommonControllerTest extends ControllerTestSupport {

	@DisplayName("현재 학기 정보를 가져온다")
	@Test
	void getCurrentTermInfo() throws Exception {
		// given
		String termName = "2023년도 2학기";
		LocalDateTime startAt = LocalDateTime.of(2023, 9, 1, 00, 00);
		LocalDateTime endAt = LocalDateTime.of(2023, 12, 15, 23, 59);

		TermResDto res = TermResDto.builder()
			.id(1L)
			.name(termName)
			.startAt(startAt)
			.endAt(endAt)
			.build();

		given(commonService.getTerm(1L)).willReturn(res);

		// when & then
		mockMvc.perform(
				get("/api/v1/term")
			)
			.andDo(print())
			.andExpect(status().isOk())
			.andExpect(jsonPath("$.code").value("200"))
			.andExpect(jsonPath("$.status").value("OK"))
			.andExpect(jsonPath("$.message").value("OK"))
			.andExpect(jsonPath("$.data").isArray());

	}

}

@WebMvcTest(CommonController.class)
@ActiveProfiles("test")
public abstract class ControllerTestSupport {

	@Autowired
	protected MockMvc mockMvc;

	@Autowired
	protected ObjectMapper objectMapper;

	@MockBean
	protected CommonService commonService;

}

순서대로 controller, controllertest, controllertestsupport 클래스 입니다

에러 내용에 보면 전혀 관계가 없는 AuthService에 대한 bean error가 뜨고 있어서 질문드립니다

2. 두 번째는 외부 api와 통신해서 구현되는 로직을 openfeign으로 사용하고 있습니다. BDDMockito로 feign client를 stub해서 테스트를 짜던 중 검증이 부족할 것 같다는 생각에 wiremock을 이용해서 테스트를 진행하려 하는데 best practice를 찾지 못하고 있습니다. 혹시 이에 대한 좋은 자료나 실무에서 사용하는 테스트 케이스가 있을지 궁금해서 질문드립니다

@WebMvcTest(CommonController.class)
@ActiveProfiles("test")
public class CommonControllerTest extends ControllerTestSupport {

    @MockBean
    private CommonService commonService;

    // 테스트 메소드 코드

}
