To resolve the above issue I try to run the script using $Env: K6_BROWSER_ENABLED=‘true’; k6 run browser-test.js
But again getting an error

Hi @ankushakhotele1, welcome to the community forum!

Please share more information with us:
Which K6 version do you use?
Can you share the test script with us?

Thanks

Hi @bandorko
k6 version is 0.45.1
and I am using code from official site

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

export const options = {
scenarios: {
ui: {
executor: ‘shared-iterations’,
options: {
browser: {
type: ‘chromium’,
},
},
},
},
}

export default async function () {
const page = browser.newPage();

try {
await page.goto(‘https://test.k6.io/’);
page.screenshot({ path: ‘screenshots/screenshot.png’ });
} finally {
page.close();
}
}

It doesn’t work for me either with the v0.45.1. The best you can do is to upgrade k6 to the latest version (v0.52.0 currently), but your script works from the version v0.46.0. If you have to stick to the v0.45.1, the API is a bit different for that. You can find an example for that version here: launch([options])

Please let me know if it helps.

I tried but again getting an error

@ankushakhotele1: I assume, you tried to run the example I linked as is, but it is just an example.
I modified your script to be able to run with v0.45.1

import { chromium } from 'k6/experimental/browser';

export const options = {
    scenarios: {
        ui: {
            executor: 'shared-iterations',
            options: {
                browser: {
                    type: 'chromium',
                },
            },
        },
    },
}

export default async function () {
    const browser = chromium.launch()
    const context = browser.newContext();
    const page = context.newPage();

    try {
        await page.goto('https://test.k6.io/');
        page.screenshot({ path: 'screenshots/screenshot.png' });
    } finally {
        page.close();
    }
}

Please try this one with v0.45.1, but I suggest to upgrade your k6 to the most recent version and use your original script with it.

I have updated the k6 and it is working fine now.
Thank you so much for the help
