Hi everyone,
I’ve the following issue : I’m currently scripting a user journey. The authentication needs to be refreshed every 5 seconds while I’m running my test.
In other load testing tools I would have use a while loop inside a fork but here, I don’t even see a correct solution.
has anyone already faced this problem ? How did you solved it ?
Thanks in advance !
Hi @camillegr,
welcome to the community forum 
If you can use a dedicated token per VU then you can check the time elapsed from the last refresh and execute a new one after 5 seconds.
var refreshed = 0;
export default function() {
var diff = new Date() - refreshed
if (diff > 4999) {
console.log(`refresh the token`)
refreshed = new Date()
}
}
Even better if you create an HTTP wrapper where this logic is executed before each request so the code will be cleaner.
When the PR for #882 will be merged then a setTimeout could be a valid alternative. You can subscribe to it to know when it will be available.
Hi @codebien,
I think the http wrapper is a good solution. I’ll take a look at it.
thanks for your answer !
in my scenario, i want to generate a token and use it for 10 mins (validity ) Please help me to understand more about this logic, Where should we add this code, should we add this to generate token API or before using a token
my scenario looks like
import { group } from ‘k6’;
import {check , sleep} from ‘k6’;
import http from ‘k6/http’;
import { htmlReport } from “K6 Load Test: <%= title %>”;
import { textSummary } from ‘https://jslib.k6.io/k6-summary/0.0.1/index.js’
import { SharedArray } from “k6/data”;
import papaparse from “https://jslib.k6.io/papaparse/5.1.1/index.js”;
import encoding from ‘k6/encoding’;
import { findBetween } from ‘https://jslib.k6.io/k6-utils/1.2.0/index.js’;

Thanks for opening a separate thread @Sreenivas, we’ll follow up on Generated Token every 10 mins and use it during load test.
Cheers!
