Test에서 아래 메서드를 추가하여 메모리에 있는 값을 초기화 시키는 것은 이해했습니다. @AfterEach public void afterEach() { repository.clearStore(); } 그런데, 아래 메서드를 추가하기 전에, 왜 MemoryMemberRepository class에서, 아래 메서드를 추가해야 하는지 모르겠습니다! public void clearStore() { store.clear(); } 제가 Test 코드를 처음 작성하는데 이해가 되지 않아서 질문드립니다! 감사합니다.

Item newItem = itemRepository.save(item); model.addAttribute("item",newItem); 즉 , 이 과정이 어떻게 생략되서 작동되는지 원리가 궁금합니다.

안녕하세요 섹션2 HTTP요청 데이터 -POST HTML Form 강의에서 hello-form에서 username과 age 를 입력하고 제출 버튼을 누르면 f12에서 이렇게 request-param을 확인하셨는데 저는 제출을 눌러도 이게 뜨지 않습니다. 그러나 콘솔에서는 getParameter()로 값을 정상적으로 출력을 하는데 f12에서는 왜 확인이 안될까요?
