## Im Detail { #in-detail }

Der Marker `@pytest.mark.anyio` teilt pytest mit, dass diese Testfunktion asynchron aufgerufen werden soll:

Ahora, ejecuta el comando `fastapi` con tu archivo:

<div class="termy">

```console
$ fastapi dev main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)

</div>

Y abre la documentación en <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.

Agora, execute o comando `fastapi` com o seu arquivo:

## Check the Docs { #check-the-docs }

You can see the defined cookies in the docs UI at `/docs`:

<div class="screenshot">
<img src="/img/tutorial/cookie-param-models/image01.png">
</div>

/// info

Have in mind that, as **browsers handle cookies** in special ways and behind the scenes, they **don't** easily allow **JavaScript** to touch them.

## Instala dependencias { #install-dependencies }

Asegúrate de crear un [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, activarlo e instalar `jinja2`:

<div class="termy">

```console
$ pip install jinja2

---> 100%
```

</div>

## Usando `Jinja2Templates` { #using-jinja2templates }

* Importa `Jinja2Templates`.
* Crea un objeto `templates` que puedas reutilizar más tarde.

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

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

</div>

/// info

If you are planning to use digital signature algorithms like RSA or ECDSA, you should install the cryptography library dependency `pyjwt[crypto]`.

Перед развертыванием убедитесь, что вы вошли в систему:

<div class="termy">

```console
$ fastapi login

You are logged in to FastAPI Cloud 🚀
```

</div>

Затем разверните приложение:

<div class="termy">

```console
$ fastapi deploy

Deploying to FastAPI Cloud...

✅ Deployment successful!
