하지만 비동기 함수를 사용하여 테스트 코드를 작성하는 것은 매우 유용할 수 있습니다.
예를 들면 데이터베이스에 비동기로 쿼리하는 경우를 생각해봅시다.
FastAPI 애플리케이션에 요청을 보내고, 비동기 데이터베이스 라이브러리를 사용하여 백엔드가 데이터베이스에 올바르게 데이터를 기록했는지 확인하고 싶을 때가 있을 겁니다.

이런 경우의 테스트 코드를 어떻게 비동기로 작성하는지 알아봅시다.

## pytest.mark.anyio

앞에서 작성한 테스트 함수에서 비동기 함수를 호출하고 싶다면, 테스트 코드도 비동기 함수여야합니다.
AnyIO는 특정 테스트 함수를 비동기 함수로 호출 할 수 있는 깔끔한 플러그인을 제공합니다.
