JUnit5에서 @Autowired사용 이유

컨테이너가 2개 생성될 줄은 생각 못했는데, 답변 감사합니다!!

JUnit5에서 @Autowired사용 이유

드라이브 링크입니다. https://drive.google.com/file/d/1yZm0825uOExt2y540G6kuO3HNJtjuB1Z/view?usp=sharing 실행 방법은 21~25줄의 코드를 이용해 test디렉토리의 service/MemberServiceTest의 회원가입 단위테스트를 실행하면 테스트가 정상적으로 실행되고, 21~25를 주석처리 하고 27~29줄을 이용해 테스트를 실행하면 테스트에 실패합니다. 궁금한 점 spring강의를 들을 때 AnnotationConfigApplicationContext를 이용해 bean을 가져와 테스트를 진행하셔서 제가 임의로 @Autowired가 아닌 AnnotationConfigApplicationContext를 이용해 bean을 가져와 진행해봤는데 테스트에 실패했습니다. AnnotationConfigApplicationContext와 @Autowired의 차이점을 구글링해 찾아봤지만 잘 이해가 가지않아 질문 남깁니다. 아래는 회원가입 테스트 실패 디버깅 코드 전체입니다. 2022-08-07 17:30:06.419 INFO 4131 --- [ main] o.s.t.c.transaction.TransactionContext :
