This is documentation for the next version of K6. For the latest stable release, go to the latest version.
WebSocket.onerror
A handler for a WebSocket connection error
event.
For multiple, simultaneous event handlers, use WebSocket.addEventListener()
.
Example
A k6 script that initiates a WebSocket connection and sets up a handler for the error
event.
import { WebSocket } from 'k6/experimental/websockets';
export default function () {
const ws = new WebSocket('ws://localhost:10000');
ws.onerror = (e) => {
console.log(e);
ws.close();
};
}
The preceding example uses a WebSocket echo server, which you can run with the following command:
$ docker run --detach --rm --name ws-echo-server -p 10000:8080 jmalloc/echo-server
