How can I use assertions in Puppeteer?

You can use assertions in Puppeteer by integrating it with testing libraries like Jest or Mocha. Would you like an example?

Yes, please provide an example of using assertions with Jest.

Sure! Here's a simple example:

const puppeteer = require('puppeteer');
const { expect } = require('jest');

test('Page title is correct', async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com');
  const title = await page.title();
  expect(title).toBe('Example Domain');
  await browser.close();
});

What other assertions can I use in Puppeteer?

You can assert on various elements like checking if an element exists, its text content, or its attributes. Would you like more examples?
