WCAG 2.2 compliance testing combines automated scanning with manual validation. Use axe-core or Pa11y to automatically detect violations against WCAG 2.2 Level AA standards, then manually verify keyboard navigation, screen reader compatibility, and color contrast to ensure full compliance across all user interactions.

Yes. Integrate axe-core with Playwright or use Pa11y and Lighthouse to run automated accessibility scans on every code change. These tools generate violation reports that flag WCAG issues before release, enabling continuous compliance validation without manual intervention each build.

Screen reader validation requires testing with JAWS, NVDA, or VoiceOver to verify semantic HTML, ARIA attributes, and navigation flows. Combine this manual testing with automated checks from axe-core to catch common issues like missing alt text, improper heading structure, and broken landmark roles.

Keyboard navigation validation ensures all interactive elements are reachable via Tab key, focus is visible, and logical tab order exists. Test manually by navigating your site without a mouse, then use automated tools to detect missing keyboard handlers and ARIA attributes that enable assistive technology access.

Yes. Color contrast is a WCAG 2.2 requirement for perceivable content. Use automated tools like axe-core or Lighthouse to identify text and UI elements that fail contrast ratios, then remediate by adjusting foreground or background colors to meet AA or AAA standards for readability.

Automated tools detect 30–50% of accessibility issues, including contrast failures and missing ARIA labels. Manual testing with keyboard navigation and screen readers is essential to catch nuanced problems like ambiguous button labels, confusing form instructions, and poor content structure that automated scanning alone cannot identify.
