문제 설명
테스트 주도 개발 기법을
적용하기가 더 어려움
테스트 주도 개발은 결합도를 다루고 새 테스트를 만들 때 이를 우회해야 합니다.
상황에 맞는 고유한 개념
이전 예제 코드를 참고하세요. 고유성은 범위에 따라 달라집니다. 그리고 절대 전역이어서
는 안 됩니다.
멀티 스레드 환경 문제
싱글턴이 많으면 스레드에 안전하지도 않고 재진입도 불가능하며 예기치 않은 동작을 유
발합니다.
가비지 상태 누적
여러 테스트를 실행하면 싱글턴이 부풀어 오를 수 있으며, 수집되지 않으므로 가비지가
유지됩니다.
클래스 단일 책임 위반/
관심사 분리(
SoC
)
클래스의 단일 책임은 인스턴스를 생성하는 것이지 인스턴스를 관리하는 것이 아닙니다.
쉬운 접근 지점 싱글턴이 있으면 더 많은 객체가 쉽게 전역 참조를 하며 난장판이 될 수 있습니다.
의존성 지옥
클래스는 싱글턴 객체에 종속되고, 해당 싱글턴 객체는 다른 싱글턴 객체에 종속되고…
계속 이어집니다.
유연성 부족 싱글턴 객체가 생성된 후에는 교체하거나 수정할 수 없습니다.
수명 주기 관리의 어려움
싱글턴의 수명 주기를 관리하는 것은 어려울 수 있으며, 메모리 누수나 불필요한 리소스
사용으로 이어질 수 있습니다.
