```console
$ pip install "hypercorn[trio]"
---> 100%
```

</div>

### Run with Trio

Then you can pass the command line option `--worker-class` with the value `trio`:

<div class="termy">

```console
$ hypercorn main:app --worker-class trio
```

</div>

And that will start Hypercorn with your app using Trio as the backend.

* Grundlegende Startmodelle für Benutzer (ändern und entfernen Sie nach Bedarf).
* **Alembic**-Migrationen.
* **CORS** (Cross Origin Resource Sharing).
* **Celery**-Worker, welche Modelle und Code aus dem Rest des Backends selektiv importieren und verwenden können.

* Modelos básicos para usuários (modifique e remova conforme suas necessidades).
* Migrações **Alembic**.
* **CORS** (_Cross Origin Resource Sharing_ - Compartilhamento de Recursos Entre Origens).
* _Worker_ **Celery** que pode importar e usar modelos e códigos do resto do _backend_ seletivamente.

* Modèle de démarrages basiques pour les utilisateurs (à modifier et supprimer au besoin).
* Migrations **Alembic**.
* **CORS** (partage des ressources entre origines multiples, ou *Cross Origin Resource Sharing*).
* *Worker* **Celery** pouvant importer et utiliser les modèles et le code du reste du backend.

## Es ausführen

Sie können Ihre Tests wie gewohnt ausführen mit:

<div class="termy">

```console
$ pytest

---> 100%
```

</div>

## Details

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

```Python hl_lines="7"
{!../../../docs_src/async_tests/test_main.py!}
```

!!! tip "Tipp"

It will be clearly marked as deprecated in the interactive docs:

## Run it

You can run your tests as usual via:

<div class="termy">

```console
$ pytest

---> 100%
```

</div>

## In Detail

The marker `@pytest.mark.anyio` tells pytest that this test function should be called asynchronously:

```Python hl_lines="7"
{!../../../docs_src/async_tests/test_main.py!}
```

!!! tip

!!! note
    Notice that the input model is still validated.

    So, if you want to receive partial updates that can omit all the attributes, you need to have a model with all the attributes marked as optional (with default values or `None`).

...then the `description` field will **not be required**. Because it has a default value of `None`.

### Input Model in Docs

You can confirm that in the docs, the `description` field doesn't have a **red asterisk**, it's not marked as required:

<div class="screenshot">
<img src="/img/tutorial/separate-openapi-schemas/image01.png">
</div>

### Model for Output

But if you use the same model as an output, like here:
