Voyons comment procéder.

## pytest.mark.anyio { #pytest-mark-anyio }

Si nous voulons appeler des fonctions asynchrones dans nos tests, nos fonctions de test doivent être asynchrones. AnyIO fournit un plug-in pratique qui nous permet d'indiquer que certaines fonctions de test doivent être appelées de manière asynchrone.

## HTTPX { #httpx }

Starlette (и **FastAPI**) основаны на [AnyIO](https://anyio.readthedocs.io/en/stable/), что делает их совместимыми и со стандартной библиотекой Python [asyncio](https://docs.python.org/3/library/asyncio-task.html), и с [Trio](https://trio.readthedocs.io/en/stable/).

Starlette (e **FastAPI**) são baseados no [AnyIO](https://anyio.readthedocs.io/en/stable/), o que o torna compatível com ambos o [asyncio](https://docs.python.org/3/library/asyncio-task.html) da biblioteca padrão do Python, e o [Trio](https://trio.readthedocs.io/en/stable/).

import pytest
from httpx import ASGITransport, AsyncClient

from .main import app


@pytest.mark.anyio
async def test_root():
    async with AsyncClient(
        transport=ASGITransport(app=app), base_url="http://test"
    ) as ac:
        response = await ac.get("/")
    assert response.status_code == 200

Starlette (і **FastAPI**) базуються на [AnyIO](https://anyio.readthedocs.io/en/stable/), що робить їх сумісними як зі стандартною бібліотекою Python [asyncio](https://docs.python.org/3/library/asyncio-task.html), так і з [Trio](https://trio.readthedocs.io/en/stable/).

Starlette (ve **FastAPI**) [AnyIO](https://anyio.readthedocs.io/en/stable/) üzerine kuruludur; bu sayede Python standart kütüphanesindeki [asyncio](https://docs.python.org/3/library/asyncio-task.html) ve [Trio](https://trio.readthedocs.io/en/stable/) ile uyumludur.

Özellikle, kendi kodunuzda daha gelişmiş desenler gerektiren ileri seviye eşzamanlılık kullanım senaryoları için doğrudan [AnyIO](https://anyio.readthedocs.io/en/stable/) kullanabilirsiniz.

Starlette (et **FastAPI**) s’appuie sur [AnyIO](https://anyio.readthedocs.io/en/stable/), ce qui le rend compatible à la fois avec la bibliothèque standard [asyncio](https://docs.python.org/3/library/asyncio-task.html) de Python et avec [Trio](https://trio.readthedocs.io/en/stable/).

Starlette (y **FastAPI**) están basados en [AnyIO](https://anyio.readthedocs.io/en/stable/), lo que lo hace compatible tanto con el [asyncio](https://docs.python.org/3/library/asyncio-task.html) del paquete estándar de Python como con [Trio](https://trio.readthedocs.io/en/stable/).

Comme ce petit exemple n'a besoin d'aucune instruction `await`, nous ajoutons un `await anyio.sleep(0)` pour donner une chance à la boucle d'événements de gérer l'annulation.

Cela serait encore plus important avec des flux volumineux ou infinis.
