통합테스트 에러 해결 방법

현재 Create 통합 테스트 작성의

통합 테스트 작성하기 까지 다 들은 상태인데요,

분명 똑같이 따라했는데

A worker process has failed to exit gracefully and has been force exited. This is likely caused by tests leaking due to improper teardown. Try running with --detectOpenHandles to find leaks.

위의 에러 메세지가 뜨더라고요..

구글링해서

package.json에

"test": "jest --runInBand --detectOpenHandles"

이렇게 해줬는데

이렇게 하니까 이번엔

ReferenceError: You are trying to `import` a file after the Jest environment has been torn down.

이 에러가 뜹니다;;

계속 구글링해보고 있긴한데 해결이 안되서

질문 남깁니다.
