이를 지원하기 위해 Pydantic 자체에서 몇몇 변경점이 있었습니다.

이전 스크린샷은 <a href="https://code.visualstudio.com" class="external-link" target="_blank">Visual Studio Code</a>를 찍은 것입니다.

하지만 똑같은 편집기 지원을 <a href="https://www.jetbrains.com/pycharm/" class="external-link" target="_blank">PyCharm</a>에서 받을 수 있거나, 대부분의 다른 편집기에서도 받을 수 있습니다:

`AsyncClient` 가 테스트를 실행시켰다는 것을 확인하기 위해
`LifespanManager` from <a href="https://github.com/florimondmanca/asgi-lifespan#usage" class="external-link" target="_blank">florimondmanca/asgi-lifespan</a>.확인해주세요.

## 그 외의 비동기 함수 호출

테스트 함수가 이제 비동기 함수이므로, FastAPI 애플리케이션에 요청을 보내는 것 외에도 다른 `async` 함수를 호출하고 `await` 키워드를 사용 할 수 있습니다.

Und der Rest wird von **FastAPI** gehandhabt.

**FastAPI** не требует использовать SQL (реляционную) базу данных. Но вы можете использовать любую базу данных, которую хотите.

Здесь мы рассмотрим пример с использованием <a href="https://sqlmodel.tiangolo.com/" class="external-link" target="_blank">SQLModel</a>.
