Build reliable browser checks using observed UI state, semantic locators, bounded waits, isolated test data and explicit outcome verification.
Why this skill is useful
Provides specific patterns and scripts for reliable browser automation that the AI wouldn't generate on its own.

What this skill does
Browser Automation Use the browser tool already selected by the user or installed in the project. Playwright, Puppeteer and Selenium have different integrations; choose from actual requirements rather than unsupported success-rate claims. Modified by AAS maintainers on 2026-09-05: removed unverified comparisons and bypass defaults, clarified waiting and evidence limits. Separate tests of applications you control from interaction with an existing authenticated browser. Do not replace the latter with a fresh unauthenticated session or extract credentials to make an automation test work. Detailed Guide Read the detailed guide before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely. Playwright Test Example """ import { test, expect } from '@playwright/test'; // Each test runs in isolated browser context test('user can add item to cart', async ({ page }) => { // Fresh context - no cookies, no storage from other tests await page.goto('/products'); await page.getByRole('button', { name: 'Add to Cart' }).click(); await expect(page.getByTestId('cart-count')).toHaveText('1'); }); test('user can remove item from cart', async ({ page }) => { // Completely isolated - cart is empty await page.goto('/cart'); await expect(page.getByText('Your cart is empty')).toBeVisible(); }); """ Good Examples (User-Facing) """ // By role - THE BEST CHOICE await page.getByRole('button', { name: 'Submit' }).click(); await page.getByRole('link', { name: 'Sign up' }).click(); await expect(page.getByRole('heading', { name: 'Dashboard' })).toBeVisible(); await page.getByRole('textbox', { name: 'Search' }).fill('query'); // By text content await expect(page.getByText('Welcome back')).toBeVisible(); await page.getByText(/Order #\d+/).click(); // Regex supported // By label (forms) await page.getByLabel('Emai …
