import { sleep } from 'k6';
import { chromium } from 'k6/x/browser';

export default async function () {
    const browser = chromium.launch({ headless: false });
    const page = browser.newPage();

    await page
        .goto('https://test.k6.io/', { waitUntil: 'networkidle' })
        .finally(() => {
            page.close();
            browser.close();
        });

    await page
        .goto('https://test.k6.io/contacts.php', { waitUntil: 'networkidle' })
        .finally(() => {
            page.close();
            browser.close();
        });

   sleep(30)
}
