memberController에서는 @Autowired를 이용하여 의존관계를 설정해주어야 한다.

@Component annotation을 통해

MemberController -> MemberService -> MemoryMemberRepository 순으로

의존관계를 주입하고 있다.

Test

MemberServiceTest.class

매 테스트 마다

repository를 만들어주고 memberService에

넣어줘서 한 테스트에 각기 다른 객체를 이용할 수 있다.

 

그리고 AfterEach를 통해 각 테스트 후에 clear을 해주므로

static한 hashMap이 클리어되어 이후 새로운 MemeryMemberRepository를 생성해도

static한 hasjMap은 비어 있게 된다.
