@Test
@Transactional
public void join(Member member) {

Member member2 = new Member();

// when
Long savedId2 = memberService.join(member2);
// then
Member one = memberRepository.findOne(savedId2);
assertEquals(member2, one);영어 잘하거나 눈썰미 좋은 사람은 바로 눈치 챘을 듯 하다.
No ParameterResolver registered for parameter [jpabook.jpashop.domain.Member member] in method [public void jpabook.jpashop.service.MemberServiceTest.join(jpabook.jpashop.domain.Member)]
No ParameterResolver 매개변수 resolver가 없댄다.
registered for parameter 매개변수에 대한 등록된
=> 매개변수에 대해 등록된 resolver가 없댄다.
해당 파라미터는 Member 타입. member 랜다.
이게 테스트 클래스에 있는 join() 메서드에 있단다.
=> Test클래스에 있는 메서드의 파라미터로 넣어준 녀석에 대한 리졸버가 없댄다. 그래서 에러랜다.
예외 발생은 junit 에서 시작된 듯 하다.
org.junit.jupiter.api.extension.ParameterResolutionException
결국, join 메서드 에 잠깐 정신이 나가 입력한 인자값 Member member 를 제거 하는 것으로 해당 오류는 제거 됐다.
종합
- 매개변수를 주입하지도 않은 매서드에 대해 테스트를 진행 하려고 하니 에러가 발생했다.
- 테스트 단이 아닐 경우엔 메서드를 호출하며 등록한 인자값을 넣어주지 않으면 빨간줄이 그어져 발견하기 쉬운데, 테스트 단에서 테스트용 메서드 작성 후 바로 돌려 버리니 해당 에러가 눈에 보이지 않았다.
- 아아.. 그냥 단순 코드 작성상의 문제였는데 이게 junit 쪽에서 발생시키는 익셉션까지 가는구나..
