Es basiert auf <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, welches wiederum auf der Grundlage von requests konzipiert wurde, es ist also sehr vertraut und intuitiv.

Damit können Sie <a href="https://docs.pytest.org/" class="external-link" target="_blank">pytest</a> direkt mit **FastAPI** verwenden.

## Verwendung von `TestClient`

# WebSockets

You can use <a href="https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API" class="external-link" target="_blank">WebSockets</a> with **FastAPI**.

## Install `WebSockets`

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and install `websockets`:

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

## Verifique o usuário

Aqui está um exemplo mais completo.

Utilize uma dependência para verificar se o usuário e a senha estão corretos.

Para isso, utilize o módulo padrão do Python <a href="https://docs.python.org/3/library/secrets.html" class="external-link" target="_blank">`secrets`</a> para verificar o usuário e senha.

Используя эти инструменты, Вы можете напрямую задействовать <a href="https://docs.pytest.org/" class="external-link" target="_blank">pytest</a> с **FastAPI**.
