1const { chromium } = require('playwright');2(async () => {3 const browser = await chromium.launch({ headless: false });4 const page = await browser.newPage();5 await page.screenshot({ path: 'google.png' });6 await browser.close();7})();8Now, we have to set the root of the page to be expired at a particular time. To do this, we use the markRootExpiredAtTime() method of the Playwright Internal API. The method takes in the time at which we want to expire the root. The time is in milliseconds. In the above example, we set the time to 1000 milliseconds, which is equal to 1 second. This means that the root will be expired after 1 second. This means that the root will be expired after 1 second. The code to set the root to be expired after 1 second is as follows:9const { chromium } = require('playwright');10(async () => {11 const browser = await chromium.launch({ headless: false });12 const page = await browser.newPage();13 await page.screenshot({ path: 'google.png' });14 await page._frameManager._mainFrame._context._delegate.markRootExpiredAtTime(1000);15 await browser.close();16})();17const { chromium } = require('playwright');18(async () => {19 const browser = await chromium.launch({ headless: false });20 const page = await browser.newPage();21 await page.screenshot({ path: 'google.png' });
