How can I use headless browsers for testing my web applications?

Headless browsers allow you to run web applications in a simulated environment without a graphical user interface. You can use tools like Puppeteer or Selenium to automate testing.

What are the benefits of using headless browsers over traditional testing methods?

Headless browsers are faster since they don't render a UI, making them ideal for automated testing. They also consume less memory and can run in environments without a display.

Can you give me an example of a simple test script using Puppeteer?

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');
  const title = await page.title();
  console.log(title);
  await browser.close();
})();

Are there any limitations I should be aware of when using headless browsers?

Yes, some limitations include potential differences in rendering compared to full browsers, and certain features like pop-ups or alerts may behave differently.
