<summary>Atau gunakan <code>async def</code>...</summary>

Jika kode anda menggunakan `async` / `await`, gunakan `async def`:

```Python hl_lines="9  14"
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
async def read_root():

def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```

<details markdown="1">
<summary>Və ya <code>async def</code>...</summary>

Əgər kodunuzda `async` və ya `await` vardırsa `async def` istifadə edə bilərik:

```Python hl_lines="9  14"
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
async def read_root():

Não faz diferença. O **FastAPI** sabe o que fazer.

Caso você não conheça, veja em [Async: *"Com Pressa?"*](../../async.md#com-pressa){.internal-link target=_blank} a sessão acerca de `async` e `await` na documentação.

<summary>Oder verwenden Sie <code>async def</code> ...</summary>

Wenn Ihr Code `async` / `await` verwendet, benutzen Sie `async def`:

```Python hl_lines="9  14"

app = FastAPI()


@app.get("/")
async def read_root():

/// tip | 팁

테스트를 위한 함수는 `async def` 가 아니라 `def` 로 작성됨에 주의하세요.

그리고 클라이언트에 대한 호출도 `await` 를 사용하지 않는 일반 호출입니다.

이렇게 하여 복잡한 과정 없이 `pytest` 를 직접적으로 사용할 수 있습니다.

///

/// note | 기술 세부사항

`from starlette.testclient import TestClient` 역시 사용할 수 있습니다.

/// tip | Tipp

Beachten Sie, dass die Testfunktionen normal `def` und nicht `async def` sind.

Und die Anrufe an den Client sind ebenfalls normale Anrufe, die nicht `await` verwenden.

Dadurch können Sie `pytest` ohne Komplikationen direkt nutzen.

///

/// note | Technische Details

Sie könnten auch `from starlette.testclient import TestClient` verwenden.

{* ../../docs_src/app_testing/tutorial001.py hl[2,12,15:18] *}

/// tip | Подсказка

Обратите внимание, что тестирующая функция является обычной `def`, а не асинхронной `async def`.

И вызов клиента также осуществляется без `await`.

Это позволяет вам использовать `pytest` без лишних усложнений.

///

/// note | Технические детали

Также можно написать `from starlette.testclient import TestClient`.
