Socket.setTimeout(callback, delay)
Note
A module with a better and standard API exists.
The new k6/experimental/websockets API partially implements the WebSockets API living standard.
When possible, we recommend using the new API. It uses a global event loop for consistency with other k6 APIs and better performance.
Call a function at a later time, if the WebSocket connection is still open then.
Parameter | Type | Description |
---|---|---|
callback | function | The function to call when delay has expired. |
delay | number | The delay time, in milliseconds. |
Example
JavaScript
import ws from 'k6/ws';
import { sleep } from 'k6';
export default function () {
console.log('T0: Script started');
const url = 'ws://echo.websocket.org';
const response = ws.connect(url, null, function (socket) {
console.log('T0: Entered WebSockets run loop');
socket.setTimeout(function () {
console.log('T0+1: This is printed');
}, 1000);
socket.setTimeout(function () {
console.log('T0+2: Closing socket');
socket.close();
}, 2000);
socket.setTimeout(function () {
console.log('T0+3: This is not printed, because socket is closed');
}, 3000);
});
console.log('T0+2: Exited WebSockets run loop');
sleep(2);
console.log('T0+4: Script finished');
}
