ai를 이용해 바이브 코딩을 하셨으면 TDD를 하기 더 쉬웠을것 같은데요. 전체적인 클래스에 비해 테스트 코드가 빈약한것 같습니다. 😢
ai를 활용하는 것은 좋지만 지금 교육 프로그램에 참여하신 목적에 더 알맞게 객체지향적으로 TDD 사이클을 이용해 생각하는 연습을 하시면 더 도움이 되지 않을까 싶습니다.
지금은 너무 시간에 쫓겨 미션을 수행하기 위해 급히 바이브 코딩을 하신것 같은데 그러면 이 과정에서 얻어가시는게 너무 적지 않으실까 싶습니다.

아무런 매개변수 없는 메서드를 이용하는 것이라면 matcher라는 클래스가 반드시 필요할까요?

안녕하세요.
시간이 없어서 인공지능의 힘을 빌렸,,, VIBE 코딩 어마어마하네요;;
피드백 부탁드립니다.
