Accessibility verification checks your UI for WCAG 2.1 AA compliance using automated tools like axe-core, keyboard navigation tests, screen reader readiness checks, and Lighthouse audits. Run these tests on changed components and user flows during implementation or code review, then document and attach the evidence before release.

Axe-core identifies accessibility violations in your UI by scanning for WCAG compliance issues, including improper ARIA attributes, missing alt text, color contrast failures, and structural problems. It integrates directly into your verification workflow to surface defects before they reach production.

Keyboard navigation testing verifies that users can interact with your interface using only the keyboard by checking focus order sequencing and detecting focus traps. This ensures your UI meets WCAG standards for keyboard accessibility and works for users who cannot use a mouse.

Run accessibility verification during UI implementation, after modifications, and before code reviews—before shipping to production. Automated testing catches violations early, reducing remediation cost and ensuring compliant releases with documented audit evidence.

Lighthouse audits measure accessibility compliance including screen reader readiness and ARIA naming conventions, but they are one part of a complete verification suite. Combine Lighthouse scores with axe-core tests, keyboard navigation checks, and actual screen reader validation for comprehensive WCAG alignment.

Document screenshots of your UI, axe-core console results showing no violations, keyboard navigation test results, screen reader compatibility findings, and Lighthouse accessibility scores. This evidence demonstrates WCAG 2.1 AA compliance and supports the functional and technical requirements before release.
