Browser Automation

Playwright provides a powerful browser automation API, allowing you to interact with web pages in a way that mimics real user behavior. You can perform actions like clicking buttons, filling out forms, and navigating between pages.

import { test } from '@playwright/test';

test('Example test', async ({ page }) => {
  await page.goto('https://ray.run');
  await page.click('text=Sign In');
  await page.fill('input[name="email"]', '[email protected]');
  await page.fill('input[name="password"]', 'password');
  await page.click('button[type="submit"]');
});
