## Details

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

{* ../../docs_src/async_tests/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.

///

</div>

## In Detail

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

{* ../../docs_src/async_tests/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`.
