accessibility-testing

The accessibility-testing skill is a specialized engineering toolkit designed for developers and quality assurance engineers tasked with ensuring digital products meet global inclusive design standards. It provides a robust framework for performing WCAG 2.2 compliance audits, validating screen reader compatibility, and enforcing accessibility requirements across complex web applications. By integrating seamlessly with existing CI/CD pipelines, it helps teams mitigate legal risks associated with ADA and Section 508 compliance while ensuring that applications remain usable for the over 1 billion people worldwide living with disabilities.

• Automated accessibility linting and auditing using industry-standard tools like axe-core, pa11y, and Lighthouse.

• Specialized workflows for testing POUR principles: Perceivable, Operable, Understandable, and Robust content.

• Comprehensive support for keyboard-only navigation testing and visual focus indicator verification.

• Integration with the qe-browser fleet for headless accessibility tree analysis and real-time DOM evaluation via Vibium.

• Structured reporting for compliance levels A, AA, and AAA, including remediation guidance for specific violations.

• Fleet orchestration capabilities to coordinate multiple QA agents for deep-dive audits, screen reader simulation, and color contrast validation.

• Use this skill during the development lifecycle for feature-level validation, pre-release accessibility audits, and ongoing regression testing of critical user paths.

• When running automated scans, leverage the preferred a11y-ally integration to avoid bulky dependencies like Playwright while maintaining high-fidelity reporting.

• Manual testing remains a critical component; use the provided screen reader checklists (VoiceOver, NVDA, JAWS) to augment automated results.

• Ensure color contrast ratios meet the 4.5:1 requirement for normal text and 3:1 for large text/UI elements.

• The tool accepts web URLs or local component selectors as input and generates detailed JSON reports containing violation impact analysis and actionable fix paths.
