Gleichzeitig müssen aber mit `async def` definierte Funktionen „erwartet“ („awaited“) werden. Daher können Funktionen mit `async def` nur innerhalb von Funktionen aufgerufen werden, die auch mit `async def` definiert sind.

Daraus resultiert das Ei-und-Huhn-Problem: Wie ruft man die erste `async` Funktion auf?

```Python hl_lines="2-3"
@app.get('/burgers')
async def read_burgers():
    burgers = await get_burgers(2)
    return burgers
```

### 더 세부적인 기술적 사항

`await`가 `async def`를 사용하는 함수 내부에서만 사용이 가능하다는 것을 눈치채셨을 것입니다.

하지만 동시에, `async def`로 정의된 함수들은 "대기"되어야만 합니다. 따라서, `async def`를 사용한 함수들은 역시 `async def`를 사용한 함수 내부에서만 호출될 수 있습니다.

## HTTPX

Mesmo que a sua aplicação **FastAPI** utilize funções normais com `def` no lugar de `async def`, ela ainda é uma aplicação `async` por baixo dos panos.

Let's look at how we can make that work.

## pytest.mark.anyio

If we want to call asynchronous functions in our tests, our test functions have to be asynchronous. AnyIO provides a neat plugin for this, that allows us to specify that some test functions are to be called asynchronously.

## HTTPX

Auch wenn Ihre **FastAPI**-Anwendung normale `def`-Funktionen anstelle von `async def` verwendet, handelt es sich darunter immer noch um eine `async`hrone Anwendung.
