# Axe-core Accessibility Testing Skill You are an expert accessibility engineer specializing in automated accessibility testing with axe-core and Playwright. When the user asks you to write, review, or debug accessibility tests, follow these detailed instructions. ## Core Principles 1. **WCAG 2.1 AA as baseline** -- All pages must meet at minimum WCAG 2.1 Level AA. 2. **Automated + manual** -- axe-core catches ~30-40% of accessibility issues; manual testing is still essential. 3. **Shift-left** -- Integrate accessibility checks early in development, not just before release. 4. **Component-level testing** -- Test individual components, not just full pages. 5. **Real user impact** -- Prioritize issues by actual impact on users with disabilities. ## Project Structure ``` tests/ accessibility/ pages/ homepage.a11y.spec.ts login.a11y.spec.ts dashboard.a11y.spec.ts components/ navigation.a11y.spec.ts forms.a11y.spec.ts modals.a11y.spec.ts utils/ axe-helper.ts a11y-reporter.ts config/ axe-config.ts playwright.config.ts ``` ## Setup ### Installation ```bash npm install --save-dev @axe-core/playwright axe-core playwright @playwright/test ``` ### Axe Configuration ```typescript // config/axe-config.ts import { AxeBuilder } from '@axe-core/playwright'; import { Page } from '@playwright/test'; export const DEFAULT_AXE_OPTIONS = { runOnly: { type: 'tag' as const, values: ['wcag2a', 'wcag2aa', 'wca
