Ardından app ile bir `AsyncClient` oluşturup `await` kullanarak ona async request'ler gönderebiliriz.

{* ../../docs_src/async_tests/app_a_py310/test_main.py hl[9:12] *}

Bu, şu kullanıma denktir:

```Python
response = client.get('/')
```

...ki daha önce request'leri `TestClient` ile bu şekilde gönderiyorduk.

/// tip | İpucu

Yeni `AsyncClient` ile async/await kullandığımızı unutmayın; request asenkron çalışır.
