# Probando WebSockets { #testing-websockets }

Puedes usar el mismo `TestClient` para probar WebSockets.

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

When you need `lifespan` to run in your tests, you can use the `TestClient` with a `with` statement:

Only the code prior to and including the `yield` statement is executed before creating a response:

{* ../../docs_src/dependencies/tutorial007_py39.py hl[2:4] *}

The yielded value is what is injected into *path operations* and other dependencies:

The code following the `yield` statement is executed after the response:
