accessibility-testing

To audit web accessibility, run automated axe and Lighthouse checks alongside manual keyboard and screen reader testing to identify WCAG failures. This process surfaces usability blockers and generates an actionable remediation checklist for ARIA roles, missing labels, and heading hierarchy errors.

Testing keyboard navigation and screen reader compatibility requires verifying focus visibility and tab order without a mouse. You validate functionality using assistive technologies like VoiceOver and NVDA to ensure ARIA labels are properly announced and keyboard-only users can access all features.

Automated accessibility checks are designed for CI pipelines and pre-release quality gates to catch common UI markup violations. Running axe and Lighthouse-style checks during continuous integration quickly surfaces WCAG failures before deployment, preventing compliance risks in production.

Fix ARIA labeling and heading hierarchy issues by applying proper alt text for images, adding descriptive labels to icon buttons and form fields, and structuring headings logically. Remediation guidance targets these specific semantic failures to restore screen reader compatibility and navigation.

Manual accessibility testing requires disabling CSS to validate reading order and checking zoom behavior to ensure text remains legible. This verifies that visual presentation does not break underlying document semantics and that users relying on page magnification can read content.
