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.


## HTTPX

**FastAPI** 애플리케이션이  `async def` 대신 `def` 키워드로 선언된 함수를 사용하더라도, 내부적으로는 여전히 `비동기` 애플리케이션입니다.

`TestClient`는 pytest 표준을 사용하여 비동기 FastAPI 애플리케이션을 일반적인 `def` 테스트 함수 내에서 호출할 수 있도록 내부에서 마술을 부립니다. 하지만 이 마술은 비동기 함수 내부에서 사용할 때는 더 이상 작동하지 않습니다. 테스트를 비동기로 실행하면, 더 이상 테스트 함수 내부에서 `TestClient`를 사용할 수 없습니다.
