K6 Load Testing

[kclark-scottlogic]

Adding in a load test script and equivalent tests within the script

An average-load test assesses how the system performs under typical load. Typical load might be a regular day in production or an average moment.

Average-load tests simulate the number of concurrent users and requests per second that reflect average behaviors in the production environment. This type of test typically increases the throughput or VUs gradually and keeps that average load for some time. Depending on the system's characteristics, the test may stop suddenly or have a short ramp-down period.

Example script code for load testing:

import http from 'k6/http';
import {sleep} from 'k6';

export const options = {
  // Key configurations for avg load test in this section
  stages: [
    { duration: '5m', target: 100 }, // traffic ramp-up from 1 to 100 users over 5 minutes.
    { duration: '30m', target: 100 }, // stay at 100 users for 30 minutes
    { duration: '5m', target: 0 }, // ramp-down to 0 users
  ],
};

export default () => {
  const urlRes = http.get('https://test-api.k6.io');
  sleep(1);
  // MORE STEPS
  // Here you can have more steps or complex script
  // Step1
  // Step2
  // etc.
};

Near the end of the load run there was a massive spike in the http request time before requests started to fail
