Der `TestClient` basiert auf <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a> und glücklicherweise können wir ihn direkt verwenden, um die API zu testen.

## Beispiel

The `TestClient` is based on <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, and luckily, we can use it directly to test the API.

## Example

/// tip | Dica

O callback real é apenas uma solicitação HTTP.

Quando implementando o callback por você mesmo, você pode usar algo como <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a> ou <a href="https://requests.readthedocs.io/" class="external-link" target="_blank">Requisições</a>.

# HTTP Basic Auth

For the simplest cases, you can use HTTP Basic Auth.

In HTTP Basic Auth, the application expects a header that contains a username and a password.

If it doesn't receive it, it returns an HTTP 401 "Unauthorized" error.

And returns a header `WWW-Authenticate` with a value of `Basic`, and an optional `realm` parameter.

That tells the browser to show the integrated prompt for a username and password.

# HTTP Basic Auth

Für die einfachsten Fälle können Sie <abbr title="HTTP-Basisauthentifizierung">HTTP Basic Auth</abbr> verwenden.

Bei HTTP Basic Auth erwartet die Anwendung einen Header, der einen Benutzernamen und ein Passwort enthält.

Wenn sie diesen nicht empfängt, gibt sie den HTTP-Error 401 „Unauthorized“ zurück.

Und gibt einen Header `WWW-Authenticate` mit dem Wert `Basic` und einem optionalen `realm`-Parameter („Bereich“) zurück.
