El `TestClient` está basado en <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, y afortunadamente, podemos usarlo directamente para probar la API.

/// tip | Tipp

Beachten Sie, dass benutzerdefinierte proprietäre Header hinzugefügt werden können <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">unter Verwendung des `X-`-Präfixes</a>.

`0.122.0`, используется более подходящий HTTP статус-код `401 Unauthorized`, и в ответе возвращается имеющий смысл HTTP-заголовок `WWW-Authenticate` в соответствии со спецификациями HTTP, <a href="https://datatracker.ietf.org/doc/html/rfc7235#section-3.1" class="external-link" target="_blank">RFC 7235</a>, <a href="https://datatracker.ietf.org/doc/html/rfc9110#name-401-unauthorized" class="external-link" target="_blank">RFC 9110</a>.

Но если по какой-то причине ваши клиенты зависят от старого...
