How can I use Puppeteer for performance testing?

You can use Puppeteer to automate browser actions and measure performance metrics like load times and responsiveness.

What specific metrics can I measure with Puppeteer?

You can measure metrics such as First Contentful Paint (FCP), Time to Interactive (TTI), and Speed Index.

Can you provide a sample script for measuring load time?

Sure! Here's a simple script:

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  const start = performance.now();
  await page.goto('https://example.com');
  const end = performance.now();
  console.log(`Load time: ${end - start} ms`);
  await browser.close();
})();
