You can use the same `TestClient` to test WebSockets.

For this, you use the `TestClient` in a `with` statement, connecting to the WebSocket:

/// note

For more details, check Starlette's documentation for [testing WebSockets](https://www.starlette.dev/testclient/#testing-websocket-sessions).

                as the default. This is different from `response_model_exclude_unset`
                in that if the fields are set but contain the same default values,
                they will be excluded from the response.
