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/).

В частности, вы можете напрямую использовать [AnyIO](https://anyio.readthedocs.io/en/stable/) для продвинутых сценариев конкурентности, где в вашем коде нужны более сложные паттерны.

 *       a more precisely named annotation?

## Im Detail { #in-detail }

Der Marker `@pytest.mark.anyio` teilt pytest mit, dass diese Testfunktion asynchron aufgerufen werden soll:

{* ../../docs_src/async_tests/app_a_py310/test_main.py hl[7] *}

/// tip | Tipp

Beachten Sie, dass die Testfunktion jetzt `async def` ist und nicht nur `def` wie zuvor, wenn Sie den `TestClient` verwenden.

## In Detail { #in-detail }

The marker `@pytest.mark.anyio` tells pytest that this test function should be called asynchronously:

{* ../../docs_src/async_tests/app_a_py310/test_main.py hl[7] *}

/// tip

Note that the test function is now `async def` instead of just `def` as before when using the `TestClient`.

///

Then we can create an `AsyncClient` with the app, and send async requests to it, using `await`.
