위의 코드로 테스트를 몇 번 해본 결과, 계속해서 테스트를 실패했다.

실패 사인은 HttpStatus 의 값이 200 ok 가 아니라 302 found가 발생한다는 것이었다.

뭐가 문젠지 모르겠어서 로직을 한참 들여다보며 이거 바꿔보고 저거 바꿔보고 하던 와중에, 

다음과 같이 controller를 변경하자 테스트가 성공적으로 끝났다.

 

package com.frombooktobook.frombooktobookbackend.controller.post;

import com.frombooktobook.frombooktobookbackend.domain.post.Post;
import com.frombooktobook.frombooktobookbackend.service.PostService;
import lombok.RequiredArgsConstructor;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

@RequiredArgsConstructor
@RestController
public class PostController {

    private final PostService postService;


    @PostMapping("/post")
    public ResponseEntity<PostResponseDto> CreatePost(
            @RequestBody PostCreateRequestDto requestDto) {
        try {
            Post post = postService.savePost(requestDto.toEntity());
            return ResponseEntity.ok()
                    .body(new PostResponseDto(post));
        } catch(Exception e) {
            System.out.println(e);
        }
        return ResponseEntity.ok()
                .body(new PostResponseDto(requestDto.toEntity()));
    }
}

 

오류 메세지가 뜰 것임을 예상하고 오류를 print하는 로직을 추가해본 것이었는데, 

예상과 달리 테스트가 그냥 성공으로 끝나서 조금 당황스럽기는 했으나 . . . 어쨌든 오류가 해결되었으니 기쁘긴하다 . . 

찝찝 . .
