A production-focused resource for integrating, scaling, and maintaining automated accessibility testing using axe-core, Playwright, Cypress, and Lighthouse CI. Shift compliance left and enforce WCAG standards at merge time.
Three comprehensive guides covering the full lifecycle of automated accessibility testing.
Master axe-core configuration, set up Playwright and Cypress a11y plugins, configure Lighthouse CI baselines, and establish WCAG 2.2 AA as your compliance threshold.
Set up GitHub Actions workflows, configure PR merge gates that block on critical violations, implement progressive thresholds, and enforce branch policies for continuous compliance.
Write custom axe-core rules for complex UI patterns, handle SPA routing and dynamic ARIA states, inspect the DOM for dynamic content, and support internationalization in accessibility workflows.
Accessibility issues discovered after deployment cost 10–100× more to fix than those caught during development. By embedding automated WCAG validation directly into your pull request pipeline, engineering teams can enforce compliance standards continuously—without slowing development velocity.
Automated scanners like axe-core and Lighthouse CI reliably detect 30–40% of WCAG violations: missing labels, insufficient color contrast, improper ARIA attributes, and keyboard navigation failures. Combined with progressive threshold management, teams can tighten enforcement gradually while eliminating technical debt sprint by sprint.
This site covers the complete stack: from initial tool selection and configuration, through GitHub Actions pipeline setup and PR merge gates, to writing custom axe-core rules for complex UI patterns including single-page application routing, dynamic ARIA states, and internationalized labels.
Configure axe-core for React, Vue, and vanilla JS apps. Set WCAG conformance tiers, suppress false positives, and output structured JSON for CI dashboards.
Block pull requests when critical violations are detected. Set up matrix strategies across viewport breakpoints and upload violation artifacts for team review.
Extend axe-core with custom evaluate and matches functions. Validate complex interactive components, dynamic ARIA states, and SPA routing transitions.
