Controller 클래스만 테스트할 수 없을까?
테스트 범위: Controller, Service, Repository
Service 클래스만 테스트할 수 없을까?
테스트 범위: Service, Repository
Repository 클래스만 테스트할 수 없을까?
테스트 범위: Repository

가짜 객체 (Mock object) 로 분리한다.
MockRepository
-실제 객체와 겉만 같은 객체이다.
-실제 DB 작업은 하지 않는다.
Mockito framework: Mock 객체를 쉽게 만들 수 있는 방법 제공
통합 테스트
단위테스트 (Unit Test)
-하나의 모듈이나 클래스에 대해 세밀한 부분까지 테스트가 가능하다.
-하지만 모듈 간에 상호 작용 검증은 할 수 없다.
통합 테스트 (Integration Test)
-두 개 이상의 모듈이 연결된 상태를 테스트할 수 있다.
-모듈 간의 연결에서 발생하는 에러 검증 가능하다.
Spring Boot를 이용한 통합 테스트
-통합 테스트
