How to Open Multiple Browser Sessions in Playwright?

Playwright offers the concept of BrowserContexts to manage multiple independent browser sessions within a single browser instance. This is invaluable for scenarios involving multiple users, parallel testing, or isolating browser data.

Step1: Create browser instance using below command

const browser = await chromium.launch();        

Step2; Creates a new browser context. It won't share cookies/cache with other browser contexts.

 const context1 = await browser.newContext();
 const context2 = await browser.newContext();        

Step3: Creates a new page in the browser context.

 const page1 = await context1.newPage();
 const page2 = await context2.newPage();        

Step4: First browser actions

 await page1.goto('https://youtube.com/playlist?list=PLUeDIlio4THEgPRVJRqZRS8uw8hhVNQCM&si=-US8rBdfw1kxRBnt');
    await page1.locator('#contents > ytd-playlist-video-renderer:nth-child(1)').click()
    await page1.waitForTimeout(5000);
        

Step5: Second browser actions

await page2.goto('https://youtube.com/playlist?list=PLUeDIlio4THEgPRVJRqZRS8uw8hhVNQCM&si=-US8rBdfw1kxRBnt');        

Step6: Close both browsers

await browser.close();        

Step7: Finally, this is how test looks like.

import { test, chromium } from '@playwright/test';

test('Open multiple browser sessions', async () => {
    const browser = await chromium.launch();
    
    const context1 = await browser.newContext();
    const context2 = await browser.newContext();

    const page1 = await context1.newPage();
    const page2 = await context2.newPage();

    await page1.goto('https://youtube.com/playlist?list=PLUeDIlio4THEgPRVJRqZRS8uw8hhVNQCM&si=-US8rBdfw1kxRBnt');
    await page1.locator('#contents > ytd-playlist-video-renderer:nth-child(1)').click()
    await page1.waitForTimeout(5000);

    await page2.goto('https://youtube.com/playlist?list=PLUeDIlio4THEgPRVJRqZRS8uw8hhVNQCM&si=-US8rBdfw1kxRBnt');

    await browser.close();
});        

Step8: Run the tests

npx playwright test        

Similarly, we can create 'N' numbers of browsers and perform actions by using respective page objects.
