### Automated Browser Testing Script

```javascript
const { chromium } = require('playwright');

(async () => {
  const browser = await chromium.launch();
  const page = await browser.newPage();
  await page.goto('https://www.example.com/login');
  await page.fill('#username', 'testUser');
  await page.fill('#password', 'testPass');
  await page.click('#loginButton');

  // Validate login success
  const successMessage = await page.textContent('.welcome');
  console.log(successMessage); // 'Welcome, testUser!'

  await browser.close();
})();
```

This script automates the login process for the website, filling in the username and password, and verifying the success message.
