config 와 PatterendString 타입에 대한 테스트코드 감사합니다.

근데 import 패키지 정렬 순만 틀려도 go fmt가 fail이 나네요. IDE에서 go fmt를 수행하고 커밋하는 룰을 정해야 할 것 같습니다. 저는 Goland에서 setting > Before Commit > go fmt 적용하도록 해놓겠습니다.

네 암튼 확인이 되니까 사후에 make checks를 한번 돌려주면 되고요.
그래서 이제 All checks have passed...
단, make test-cover는 54.6%, coverall은 51.5%로 차이가 있네요.

PR 등록시 reviewer를 비워놨다가
All checks have passed가 뜨면 reviewer를 할당하는 것도 좋을 것 같아요.
