k6/timers

Implement timers to work with k6’s event loop. They mimic the functionality found in browsers and other JavaScript runtimes.

Function	Description
setTimeout	Sets a function to be run after a given timeout.
clearTimeout	Clears a previously set timeout with `setTimeout`.
setInterval	Sets a function to be run on a given interval.
clearInterval	Clears a previously set interval with `setInterval`.

Note
The timing methods are available globally, like in other JavaScript runtimes, and it is unnecessary to import them from the k6/timers module.

Example

export default function () {
  const intervalId = setInterval(() => {
    console.log('This runs every 200ms');
  }, 200);

  const timeoutId = setTimeout(() => {
    console.log('This runs after 2s');

    // clear the timeout and interval to exit k6
    clearInterval(intervalId);
    clearTimeout(timeoutId);
  }, 2000);
}
