일단 memberserviceTest도 돌려서 확인했을때 중복 회원 예외에 대한 문제는 나오지를 않았습니다.

다른 질문들 확인했을때 메세지 뜨는게 달라서 안뜬다고 해서 그 메세지 자체 그대로 복붙했습니다. 에러에서는 그런게 보이지도 않았구요

db에 문제가 있는건가 싶어서 테이블 자체를 없앴다가 다시만들고 테스트 당시 db에 spring1이라는 이름의 데이터 한개 있습니다.

이 테스트 자체가 member1이랑 member2랑 이름이 같아서 중복 회원 오류를 테스트 하는거라서 spring이라는 이름으로 겹치지 않게 할려고 일부로 데이터도 spring1으로 해놨습니다.

어떤 문제때문에 지금 계속 저 오류가 뜨는건지 질문드립니다.
