How to fill out a form in Puppeteer?

To fill out a form using Puppeteer, you can use the page.type or page.select methods to populate the form fields with the desired values.

Here is an example of how you can fill out a form in Puppeteer:

Launch a new browser instance:

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
})();

Navigate to the webpage containing the form:

await page.goto('https://example.com/form');

Use page.type to fill out input fields:

await page.type('input[name=username]', 'myusername');
await page.type('input[name=password]', 'mypassword');

Use page.select to select options from dropdown menus:

await page.select('select[name=country]', 'USA');

Submit the form:

await page.click('input[type=submit]');

Close the browser instance:

await browser.close();

This is a basic example of how to fill out a form using Puppeteer. You can customize the selectors and values based on the specific form fields on the webpage you are working with.
