/// warning | Advertencia

Si tu aplicación depende de eventos de lifespan, el `AsyncClient` no activará estos eventos. Para asegurarte de que se activen, usa `LifespanManager` de <a href="https://github.com/florimondmanca/asgi-lifespan#usage" class="external-link" target="_blank">florimondmanca/asgi-lifespan</a>.

Puedes usar el mismo `TestClient` para probar WebSockets.

Para esto, usas el `TestClient` en un statement `with`, conectándote al WebSocket:
