2단계와 3단계를 같이 진행해주셨네요!
다만 하나의 커밋에 너무 많은 변경사항이 포함되어 있는 것으로 보여요 😢
이번 과정의 주요 학습 목표가 TDD인 만큼, TDD 사이클에 따라 기능을 하나씩 구현해가면서
커밋 단위를 작게 가져가는 습관을 들여보시는 걸 추천 드립니다.
몇 가지 코멘트 드렸는데, 확인 후 다시 리뷰 요청을 부탁 드리겠습니다 🔥

메서드 라인 수가 길어 보이는데, 자동차 경주 미션 때처럼 메서드의 라인 수를 줄여보면 어떨까요?
이 같은 원칙 아래에서 메소드의 라인 수를 15라인이 넘지 않도록 구현한다.

- wrapper 클래스를 사용하신 이유가 있으실까요?
BridgeStrategy
라는 이름을 통해 Bridge를 생성하는 전략임을 유추할 수 있기 때문에,
메서드 이름은build()
정도로 지어도 충분히 의미를 전달할 수 있을 것 같습니다.

다음 클래스 작성 순서 가이드를 참고해보시면 좋을 것 같습니다.

문자 ,
