- 코드 가독성 향상을 위한 함수 모듈화
  - stop_and_remove_container: 컨테이너 중지 및 제거
  - run_and_health_check_container: 컨테이너 실행 및 헬스체크
  - deploy_container: 컨테이너 배포 프로세스
  - reload_nginx: nginx 재시작

- 변수 및 상수 정리
  - ROOT_PATH, CONTAINER_IMAGE 등 상수 분리

- 백엔드 배포 로직 검증을 위한 `test_run_backend.sh` 스크립트 추가:
  - Docker, AWS, curl, nginx, sudo와 같은 모의(mock) 바이너리 지원.
  - 커스터마이징 가능한 테스트 환경과 설정 지원.
  - 인자 검증, AWS 인증, Docker 작업, Blue-Green 배포를 포함한 다양한 테스트 케이스 제공.

- 주요 기능:
  - 상세 출력을 위한 verbose 모드 지원.
  - 테스트 결과(성공 및 실패)를 추적 및 보고.
  - 장시간 실행되는 테스트의 타임아웃 감지 기능 포함.

- 테스트 시나리오:
  - 유효한 조건에서의 성공적인 배포.
  - 인자 누락, 잘못된 환경 파일, 실패한 작업(AWS ECR 로그인, Docker pull 등)으로 인한 실패.
  - Blue-to-Green 및 Green-to-Blue 배포 시 유효성 검증.

- 환경 변수 지원 추가:
  - `ROOT_PATH`, `HEALTH_CHECK_MAX_RETRIES`, `HEALTH_CHECK_INTERVAL`을 환경 변수로 설정 가능하도록 수정.

- 배포 인자 검증 로직 강화:
  - 환경 변수 파일 존재 여부 및 읽기 권한 확인 추가.

- AWS ECR 인증 과정 개선:
  - AWS 로그인 실패 시 에러 메시지를 출력하고 스크립트를 종료하도록 수정.
  - 인증 성공 여부를 명확히 로그로 출력.

- Docker 이미지 풀링 및 배포 과정 안정화:
  - 이미지 풀링 실패 시 에러 메시지를 출력하고 스크립트를 종료하도록 처리.
  - Blue/Green 배포 로직 메시지를 가독성 높게 수정.

테스트를 통해 발견된 문제를 해결하고, 스크립트의 안정성과 유연성을 강화했습니다.
