`.add_task()` 함수는 다음과 같은 인자를 받습니다 :

- 백그라운드에서 실행되는 작업 함수 (`write_notification`).
- 작업 함수에 순서대로 전달되어야 하는 일련의 인자 (`email`).
- 작업 함수에 전달되어야하는 모든 키워드 인자 (`message="some notification"`).

## 의존성 주입

`BackgroundTasks`를 의존성 주입 시스템과 함께 사용하면 _경로 작동 함수_, 종속성, 하위 종속성 등 여러 수준에서 BackgroundTasks 유형의 매개변수를 선언할 수 있습니다.

But you see that we are having some code repetition here, writing `CommonQueryParams` twice:

# We enable this in the nightly and release builds because before uploading the
# wheels, we install them in a virtual environment and run some smoke tests on

# the other versions manually.
