## Em Detalhes

O marcador `@pytest.mark.anyio` informa ao pytest que esta função de teste deve ser invocada de maneira assíncrona:

```Python hl_lines="7"
{!../../docs_src/async_tests/test_main.py!}
```

/// tip | "Dica"

Note que a função de teste é `async def` agora, no lugar de apenas `def` como quando estávamos utilizando o `TestClient` anteriormente.

## 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`.
