junit 단위 테스트 질문 (feat. TestRestTemplate)

Question

안녕하세요. 혼자 토이프로젝트를 해보고 있는 사람입니다.문제는 프로젝트가 커질수록 이전에 하던것처럼 웹들어가서 눈으로 반복 확인하는게 쉽지 않을꺼같단 생각이 들어서 단위테스트를 해보려고 합니다.그래서 먼저 이전에 만들었던 좋아요에 대한 기능을 단위테스트 해보려고 시도했는데 3일째 에러가 나고있어요..... 각설하고, 코드를 먼저 보여드릴게요. 그리고 왜 그런지 아시는분 답변좀 부탁드립니다.... 좋아요API컨트롤러 테스트package org.my.toyproject.test; import org.junit.After; import org.junit.jupiter.api.Test; import org.junit.runner.RunWith; import

나오는건지요..?아래가 단위테스트에서 예외발생 부분입니다..!ResponseEntity responseEntity = restTemplate.postForEntity(url, requestDto, MypickResponseDto.class); 이거 왜그런지 아시는분 답변 부탁드리겠습니다...제발 ㅠㅠㅠ

해리아범 · Answer

에러 메세지에 나온 것처럼 MypickResponseDto에 들어온 값이 UTF-8로 인식할 수 없는 값이어서 에러가 난 것인데요해당 Dto에 대한 소스를 보여주시는 게 어떨까 싶어요

DongGeon2 · Answer

해리아범 음.. dto클래스 자체엔 그냥 좋아요 개수를 전달해주기 위한 변수뿐인데 문제가 될까요?? package org.my.toyproject.dto; import ... &#64;Data &#64;NoArgsConstructor &#64;AllArgsConstructor &#64;Builder public class MypickResponseDto { private int cnt; }
