Подсказка

Если вы столкнулись с `RuntimeError: Task attached to a different loop` при вызове асинхронных функций в ваших тестах (например, при использовании <a href="https://stackoverflow.com/questions/41584243/runtimeerror-task-attached-to-a-different-loop" class="external-link" target="_blank">MongoDB's MotorClient</a>), то не забывайте инициализировать объекты, которым нужен цикл событий (event loop), только внутри асинхронных функций, например, в `'@app.on_event("startup")` callback....

테스트에 비동기 함수 호출을 통합할 때 (예: <a href="https://stackoverflow.com/questions/41584243/runtimeerror-task-attached-to-a-different-loop" class="external-link" target="_blank">MongoDB의 MotorClient</a>를 사용할 때) `RuntimeError: Task attached to a different loop` 오류가 발생한다면, 이벤트 루프가 필요한 객체는 반드시 비동기 함수 내에서만 인스턴스화해야 한다는 점을 주의하세요!
예를 들어 `@app.on_event("startup")` 콜백 내에서 인스턴스화하는 것이 좋습니다.
