`TestClient` основан на <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, и, к счастью, мы можем использовать его (`HTTPX`) напрямую для тестирования API.

## Пример

В качестве простого примера, давайте рассмотрим файловую структуру, схожую с описанной в [Большие приложения](../tutorial/bigger-applications.md){.internal-link target=_blank} и [Тестирование](../tutorial/testing.md){.internal-link target=_blank}:

Por defecto, **FastAPI** convertiría automáticamente ese valor de retorno a JSON usando el `jsonable_encoder` explicado en [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank}.

Luego, detrás de escena, pondría esos datos compatibles con JSON (por ejemplo, un `dict`) dentro de un `JSONResponse` que se usaría para enviar el response al cliente.

Standardmäßig konvertiert **FastAPI** diesen Rückgabewert automatisch nach JSON, mithilfe des `jsonable_encoder`, der in [JSON-kompatibler Encoder](../tutorial/encoder.md){.internal-link target=_blank} erläutert wird.

Dann würde es hinter den Kulissen diese JSON-kompatiblen Daten (z. B. ein `dict`) in eine `JSONResponse` einfügen, die zum Senden der Response an den Client verwendet würde.
