Grafana k6

import { browser } from ‘k6/browser’;
import { check } from ‘k6’;

const users = [
{ email: ‘rohit1@test.com’, password: ‘QWNjb3VudDogMJSkJ=’, workspaceUrl: ‘https://test.Domainname.com/users/sign_in’ },
{ email: ‘sunil.nr+3838@synup.com’, password: ‘Password@123’, workspaceUrl: ‘https://Test2.Domainname.com/users/sign_in’ },
];

export const options = {
browser: {
type: ‘chromium’, // Correct placement of the browser type
},
scenarios: {
ui: {
executor: ‘shared-iterations’,
iterations: 10,
vus: 2,
maxDuration: ‘1m’,
},
},
thresholds: {
checks: [‘rate==1.0’],
},
};

export default async function () {
const page = await browser.newPage();
try {
const userIndex = __VU - 1; // Use __VU instead of VU
const { email: userEmail, password: userPassword, workspaceUrl } = users[userIndex];

await page.goto(workspaceUrl);

function getTimestamp() {
  const now = new Date();
  return `${now.getFullYear()}${String(now.getMonth() + 1).padStart(2, '0')}${String(now.getDate()).padStart(2, '0')}_${String(now.getHours()).padStart(2, '0')}${String(now.getMinutes()).padStart(2, '0')}${String(now.getSeconds()).padStart(2, '0')}`;
}

await page.locator("//input[@id='user_email']").type(userEmail);
await page.locator("//input[@id='user_password']").type(userPassword); // Correct ID
const submitButton = page.locator('input[name="commit"]');
await Promise.all([page.waitForNavigation(), submitButton.click()]);

const header = await page.locator("//span[contains(@class,'styles__Greeting')]").textContent();
check(header, {
  header: (h) => h.includes(`Hi, ${userEmail.split('@')[0]}!`), // Use backticks for template literals
});

const timestamp = getTimestamp();
await page.screenshot({ path: `screenshots/screenshot${timestamp}.png` });

} finally {
await page.close();
}
}

export function handleSummary(data) {
return {
‘TestSummaryReport.html’: htmlReport(data, { debug: true }),
};
}
for the above I am getting this error

Hi @Chetan

You have to specify the browser type inside the ui scenario. See example here: Running browser tests

I hope it helps
