@PersistenceContext 제외했는데 EntityManager 가 테스트할 때 null 입니다.

감사합니다. 정상적으로 동작 확인하였습니다.

@PersistenceContext 제외했는데 EntityManager 가 테스트할 때 null 입니다.

안녕하세요. OrderServiceTest.상품주문() 를 실행할 경우 1. Book에 대해서 RequiredArgsConstructor를 주석처리하고, PersistenceContext를 사용할 경우 정상적으로 동작 2. RequiredArgsConstructor를 사용하고 PersistenceContext를 주석처리해서 테스트를 실행할 경우 오류가 발생합니다. debug 결과 EntityManager가 null 이었습니다.
