Testing real-time applications requires multiple connected clients.

Use the following testing procedure:

1. Start the backend.
2. Open Chrome.
3. Connect to the chat application.
4. Open another browser window.
5. Connect using a different username.
6. Send a message from the first browser.
7. Verify that the second browser receives it.
8. Send a message from the second browser.
9. Verify that the first browser receives it.
10. Disconnect one browser and inspect the backend logs.

Also test room-based communication by opening separate clients and joining different rooms.

Clients in the same room should receive room messages, while clients outside that room should not.
