First, you can do a HTML5 WebSocket test against the echo server. You can also test against your own server URL.
Afterwards, you can see a walkthrough for creating a WebSocket application yourself. We host a WebSocket Echo Server at wss://socketsbay.com/wss/v2/1/demo/
Of course, you can also inspect WebSocket messages using your browser.
Using a plaintext editor, copy the following code and save it as websocket.html. Afterwards, simply open it in a browser. The page will automatically connect, send a message, echo the response, and close the connection.
