# Tester les WebSockets { #testing-websockets }

Vous pouvez utiliser le même `TestClient` pour tester les WebSockets.

Pour cela, vous utilisez `TestClient` dans une instruction `with`, en vous connectant au WebSocket :

Cette sous‑application est simplement une autre application FastAPI standard, mais c'est celle qui sera « montée » :

{* ../../docs_src/sub_applications/tutorial001_py310.py hl[11, 14:16] *}

### Monter la sous-application { #mount-the-sub-application }

Dans votre application de premier niveau, `app`, montez la sous‑application, `subapi`.

Dans ce cas, elle sera montée au chemin `/subapi` :

Vous pouvez ensuite renvoyer n'importe quel objet nécessaire, comme d'habitude (un `dict`, un modèle de base de données, etc.).

Et si vous avez déclaré un `response_model`, il sera toujours utilisé pour filtrer et convertir l'objet que vous avez renvoyé.
