# WebSocket 테스트하기

`TestClient`를 사용하여 WebSocket을 테스트할 수 있습니다.

이를 위해 `with` 문에서 `TestClient`를 사용하여 WebSocket에 연결합니다:

{* ../../docs_src/app_testing/tutorial002.py hl[27:31] *}

/// note | 참고

자세한 내용은 Starlette의 <a href="https://www.starlette.dev/testclient/#testing-websocket-sessions" class="external-link" target="_blank"> WebSocket 테스트</a>에 관한 설명서를 참고하시길 바랍니다.

{* ../../docs_src/first_steps/tutorial001_py39.py hl[7] *}

This is a Python function.

It will be called by **FastAPI** whenever it receives a request to the URL "`/`" using a `GET` operation.

In this case, it is an `async` function.

---

You could also define it as a normal function instead of `async def`:
