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

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

    <!-- Checks that the order of modifiers conforms to the suggestions in the
    Java Language specification, sections 8.1.1, 8.3.1 and 8.4.3. It is not that
    the standard is perfect, but having a consistent order makes the code more
    readable and no other order is compellingly better than the standard.
    The correct order is:

# Test Client - `TestClient`

You can use the `TestClient` class to test FastAPI applications without creating an actual HTTP and socket connection, just communicating directly with the FastAPI code.

Read more about it in the [FastAPI docs for Testing](https://fastapi.tiangolo.com/tutorial/testing/).

You can import it directly from `fastapi.testclient`:

```python
from fastapi.testclient import TestClient
```
