```console

Para usar `TestClient`, primero instala <a href="https://www.python-httpx.org" class="external-link" target="_blank">`httpx`</a>.

Asegúrate de crear un [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, activarlo y luego instalarlo, por ejemplo:

```console
$ pip install httpx
```
