How can I use Puppeteer for automated testing?

Puppeteer is a Node library that provides a high-level API to control Chrome or Chromium. You can use it for automated testing by writing scripts that simulate user interactions.

Can you give me a simple example of a test script?

Sure! Here's a basic example:

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com');
  await page.click('button#submit');
  await page.waitForSelector('div#result');
  const result = await page.$eval('div#result', el => el.textContent);
  console.log(result);
  await browser.close();
})();

What are some common challenges when using Puppeteer?

Common challenges include handling dynamic content, managing timeouts, and ensuring that your tests run consistently across different environments.

How can I debug my Puppeteer scripts?

You can debug Puppeteer scripts by using the headless: false option when launching the browser, which allows you to see the browser actions in real-time.
