FAQPage Schema
How do I test my web application for WCAG compliance?

WCAG compliance testing validates your web application against Web Content Accessibility Guidelines using automated tools like axe-core, pa11y, and Lighthouse to identify issues with ARIA attributes, keyboard navigation, and semantic HTML.

What is the best way to automate accessibility testing for ADA compliance?

Automating accessibility testing for ADA compliance involves running tools like axe-core, pa11y, and Lighthouse against your application URL to detect screen reader compatibility issues, color contrast failures, and keyboard navigation gaps.

Does automated accessibility testing check color contrast and ARIA attributes?

Automated accessibility testing checks color contrast and ARIA attributes by utilizing color-contrast-checker, axe-core, and Lighthouse to validate semantic HTML and ensure assistive technology compatibility for users with disabilities.

Can I use Lighthouse and pa11y to validate keyboard navigation and screen reader compatibility?

Lighthouse and pa11y validate keyboard navigation and screen reader compatibility by running automated audits that detect missing focus states, improper ARIA usage, and semantic HTML structural issues within your web application.

What accessibility issues can automated WCAG testing not detect?

Automated WCAG testing cannot detect all manual testing nuances, such as contextual meaning of ARIA attributes or complex screen reader workflows, which is why this skill provides manual testing guidance alongside automated audits.

Do I need to meet Section 508 compliance if my app already passes WCAG guidelines?

Meeting WCAG guidelines helps satisfy Section 508 compliance requirements, as this testing skill addresses legal compliance standards by validating assistive technology compatibility, color contrast, and semantic HTML structure.
