Migrate Classic Tests to Agent 2.0

​

Why migrate

• Same visual editing — continue building tests without code using the Web Editor
• Git-backed storage — tests are stored as Playwright code in addition to a no-code version, enabling version control, code review, and edit anywhere
• Full Stably SDK — access all AI features including AI assertions, AI actions, and autofix
• Run anywhere — execute tests in Stably Cloud, your CI/CD, or locally
• 50–80% lower costs — no more runtime auto-heal burning through credits on every run

​

Migration options

​

After migration

npx stably create "Add a test for checkout flow"

# Run in Stably Cloud
npx stably test

# Run locally with Playwright
npx playwright test

# Run in your CI/CD
# Tests work with any CI platform

​

What gets migrated

​

Example migrated test

import { test, expect } from '@stablyai/playwright-test';

test('Login flow with AI validation', async ({ page }) => {
  await page.goto('https://app.example.com/login');
  await page.fill('[name="email"]', 'user@example.com');
  await page.fill('[name="password"]', 'securePassword123');
  await page.click('button[type="submit"]');

  // AI assertion validates the visual state
  await expect(page).aiAssert(
    'The dashboard displays user profile information and recent activity'
  );
});
