영상에서는 @SpringBootTest 보다 단위테스트가 중요하다고 말씀하셨는데.. 실제 프로젝트에서는 그럼 Fake객체를 생각해 볼 수 있다고 생각됩니다. Fake객체를 사용하게 되면 Application Layer처럼 여러 객체들이 맞물려서 동작하는 과정에서 제대로 테스트를 했다고 볼 수 있나? 라는 의문이 드는데.. 영한님은 어떻게 생각하시는지 궁금합니다. AI의 답변 보다는 영한님의 개인적인 의견을 들어보고 싶습니다..!

String[] a = new String[] {“abc”, “bcd”}; 이 방법과 String[] a = {“abc”, “bcd”} 의 방법중 아래의 방법이 조금 더 깔끔하고 효율적인 코드가 아닌가요? 첫번째 방법을 사용하는 이유를 알고 싶습니다

static class TestBean에서 @Autowired를 3개를 했지만 3개가 등록이 되는건 아니라고 하셨는데 위에서 저렇게 print를 했을때에는 나오지 않더라구요... 어떻게 해야지 밑에 @Autowired중에 잘 들어간 함수들을 출력해서 직접 볼 수 있을지가 궁금합니다. 해당 코드를 실행했을 때의 결과는 다음과 같습니다.

(예/아니오) 네 [질문 내용] 안녕하세요? 생성자 주입에 대해서 질문이 있습니다. 앞서서 영한님의 강의에서, bean을 통해서 역할과 책임을 구분한다는 이야기를 많이 해주셨습니다. app config에서 배우를 정하고, 각 클래스들은 그냥 자신의 역할에만 집중한다는 비유를 들어서 말씀해주셨는데요 생성자를 직접 주입하는 방식은 사실 기존의 말씀과 상반되는 내용같아서, 제가 제대로 이해한 게 맞는지 싶어서 질문드립니다. 비유를 사용하여 그대로 말씀을 드리자면, '불변, 필수'의 관계에서는 앞서 말씀과 다르긴하지만, 생성자 주입을 통해 그냥 하나의 클래스에서 배우도 정하고 역할도 스스로 하는 게 맞을까요? 추가로, 만약 생성자를 주입해주는 방식만 사용한다고 하면, (싱글톤이라는 기능을 제외할 때)사실 빈을 왜 사용하는지?도 의문이 자연스럽게 듭니다..!

MemoryRepository의 Map의 키워드가 static으로 하면되네요.... 학습자료 보니깐 static이였네요 ㅠㅠ
