utils
Note
The source code for this library can be found in the grafana/k6-jslib-utils GitHub repository.
The utils
module contains number of small utility functions useful in every day load testing.
Simple example
import { sleep } from 'k6';
import http from 'k6/http';
import {
randomIntBetween,
randomString,
randomItem,
uuidv4,
findBetween,
} from 'https://jslib.k6.io/k6-utils/1.4.0/index.js';
export default function () {
const res = http.post(`https://test-api.k6.io/user/register/`, {
first_name: randomItem(['Joe', 'Jane']), // random name
last_name: `Jon${randomString(1, 'aeiou')}s`, //random character from given list
username: `user_${randomString(10)}@example.com`, // random email address,
password: uuidv4(), // random password in form of uuid
});
// find a string between two strings to grab the username:
const username = findBetween(res.body, '"username":"', '"');
console.log('username from response: ' + username);
sleep(randomIntBetween(1, 5)); // sleep between 1 and 5 seconds.
}
