/// tip

Notice that the testing functions are normal `def`, not `async def`.

And the calls to the client are also normal calls, not using `await`.

This allows you to use `pytest` directly without complications.

///

/// note | "Technical Details"

You could also use `from starlette.testclient import TestClient`.

Mas há situações específicas onde é útil utilizar o objeto `Request`.

## Utilize o objeto `Request` diretamente

Vamos imaginar que você deseja obter o endereço de IP/host do cliente dentro da sua *função de operação de rota*.

Para isso você precisa acessar a requisição diretamente.

type xdsAddr struct {
	gcpProject, host, istiod string
}

func getXdsAddressFromWebhooks(client kube.CLIClient) (*xdsAddr, error) {
	webhooks, err := client.Kube().AdmissionregistrationV1().MutatingWebhookConfigurations().List(context.Background(), metav1.ListOptions{
		LabelSelector: fmt.Sprintf("%s=%s,!%s", label.IoIstioRev.Name, client.Revision(), label.IoIstioTag.Name),
	})
	if err != nil {
		return nil, err
	}

Isso é equivalente a:

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

...que nós utilizamos para fazer as nossas requisições utilizando o `TestClient`.

/// tip | "Dica"

Note que nós estamos utilizando async/await com o novo `AsyncClient` - a requisição é assíncrona.
