갑자기 중복_회원_예외가 Tests failed 떠서 질문드립니다.

안녕하세요 스프링 데이터 JPA를 수강하던 중에

@Test 중복_회원_예외 

부분에서 Tests가 failed 되어 질문합니다.

분명 setName으로 설정해준 값도 같은데 말이죠..

왜 failed가 됐고 성공하려면 어떻게 해야할까요?

 

다음은 에러 코드입니다.

다음은 MemberServiceIntegrationTest의 중복_회원_예외 부분입니다.

@Test
public void 중복_회원_예외() throws Exception {
    //Given
    Member member1 = new Member();
    member1.setName("spring");
    Member member2 = new Member();
    member2.setName("spring");

    //When
    memberService.join(member1);
    IllegalStateException e = assertThrows(IllegalStateException.class,
            () -> memberService.join(member2));//예외가 발생해야 한다.

    assertThat(e.getMessage()).isEqualTo("이미 존재하는 회원입니다.");
}

 

다음은 MemberService의 join부분입니다.

@Transactional
public class MemberService {

    //private final MemberRepository memberRepository = new MemoryMemberRepository();
    private final MemberRepository memberRepository;

    // 외부에서 memberRepository를 넣어준다. ★★(DI : Dependency Injection)
    @Autowired
    public MemberService(MemberRepository memberRepository){
        this.memberRepository = memberRepository;
    }
    /**
     * 회원가입
     */
    public Long join(Member member){

        validateDuplicateMember(member); // 중복회원 검증
        //System.out.println("~~~ MemberService join save 직전");
        memberRepository.save(member);
        //System.out.println("~~~ MemberService join save 직후");
        return member.getId();

    }

    private void validateDuplicateMember(Member member) {
        memberRepository.findByName(member.getName())
                .ifPresent(m -> {
                    throw new IllegalStateException("~~~ 이미 존재하는 회원입니다. validateDuplicateMember");
                });
    }

    /**
     * 전체 회원 조회
     */
    public List<Member> findMembers(){
        return memberRepository.findAll();
    }

    public Optional<Member> findOne(Long memberId){
        return memberRepository.findById(memberId);
    }
}

감사합니다 갑자기 잘 되던 부분이 안돼서 당황스럽네요..
