[10] mutsa-SNS 5일차 - (1) Post 조회 기능 TestCode 추가

post 조회 기능에 대한 testCode를 추가하였다.

postController와 postService에 대하여 testCode를 추가하였다.

 

1. PostControllerTest

@WebMvcTest(PostController.class)
class PostControllerTest {
    @Autowired
    MockMvc mockMvc;

    @MockBean
    PostService postService;

    @Autowired
    ObjectMapper objectMapper;

    //포스트 상세 테스트
    @Test
    @DisplayName("1번글 조회 성공")
    @WithMockUser
    void post_detail_success() throws Exception {

        PostDto postDto = PostDto.builder()
                .id(1)
                .title("aaa")
                .body("bbb")
                .userName("ccc")
                .build();

        when(postService.detailPost(any())).thenReturn(postDto);

        mockMvc.perform(get("/api/v1/posts/1")
                        .with(csrf()))
                .andExpect(status().isOk())
                .andExpect(jsonPath("$.result.id").value(postDto.getId()))
                .andExpect(jsonPath("$.result.title").value(postDto.getTitle()))
                .andExpect(jsonPath("$.result.body").value(postDto.getBody()))
                .andExpect(jsonPath("$.result.userName").value(postDto.getUserName()))
                .andDo(print());

    }

    @Test
    @DisplayName("최신글 정렬 - pageable test")
    @WithMockUser
    void post_all_success() throws Exception {
        
        mockMvc.perform(get("/api/v1/posts")
                        .param("sort", "createdAt,desc"))
                .andExpect(status().isOk())
                .andDo(print());

        ArgumentCaptor<Pageable> pageableCaptor = ArgumentCaptor.forClass(Pageable.class);
        verify(postService).getPostAll(pageableCaptor.capture());
        PageRequest pageable = (PageRequest) pageableCaptor.getValue();

        assertEquals(Sort.by(DESC, "createdAt"), pageable.getSort());
        
    }


}

포스트 상세 조회 Test

• postService가 postDto를 return하도록 설정
• /api/v1/posts/1 에 조회하였을 때, postDto의 id, title, body, userName과 동일한지 검증

최신글 정렬 - pageable test

• controller에서 사용한 pageable의 sort 방식 검증 (createdAt의 시간으로 최신순 정렬)

2. PostServiceTest

public class PostServiceTest {

    PostService postService;

    PostRepository postRepository = mock(PostRepository.class);
    UserRepository userRepository = Mockito.mock(UserRepository.class);

    @BeforeEach
    void setUp() {
        postService = new PostService(postRepository, userRepository);

    }

    @Test
    @DisplayName("조회 성공")
    void success_post_get() {

        User user = User.builder()
                .id(1)
                .userName("userName")
                .password("password")
                .role(UserRole.USER)
                .build();

        Post post = Post.builder()
                .id(1)
                .user(user)
                .title("title")
                .body("body")
                .build();


        given(postRepository.findById(post.getId())).willReturn(Optional.of(post));

        PostDto postDto = postService.detailPost(post.getId());
        //postDto userName == User userName
        assertEquals(user.getUserName(), postDto.getUserName());


    }

}

PostDto의 userName과  test 클래스의 포스트의 작성자의 이름이 동일한지 체크
