Accessibility Testing
axe-core is the open source accessibility testing engine behind most automated a11y tooling: axe DevTools browser extension, @axe-core/playwright, jest-axe, and commercial tools like Deque's axe DevTools Pro. Understanding how axe works — and how to configure it — determines whether your automated accessibility testing is actually
Accessibility Testing
Simple semantic HTML is enough for most UI elements — buttons, links, forms, headings. But complex interactive patterns like modals, tabs, accordions, and disclosure menus don't have native HTML equivalents. These require ARIA roles and attributes to communicate structure and state to assistive technology. The ARIA Authoring Practices Guide
Testing
Accessibility compliance is not a checkbox. Running an automated scanner and calling it done leaves the majority of real accessibility barriers undetected. This guide covers how to actually test for WCAG 2.1 and 2.2 compliance — automated tools, manual techniques, and how to fit both into a development workflow.
Accessibility Testing
Most teams integrate @axe-core/playwright and call it done. You get a scan, you fix the violations, you ship. But axe-core catches maybe 30–40% of real accessibility issues. The rest — focus management failures, broken ARIA live regions, keyboard traps, flawed reading order — require behavioral testing that axe
Accessibility Testing
Color contrast and keyboard navigation are two of the most commonly failed WCAG criteria. Color contrast (SC 1.4.3) requires a 4.5:1 ratio for normal text and 3:1 for large text. Keyboard accessibility (SC 2.1.1) requires all functionality to be operable from a keyboard.
Testing
WCAG 2.1 was the first version of the Web Content Accessibility Guidelines to explicitly address mobile. Applying it to native iOS and Android apps requires mapping each criterion to platform-specific implementation patterns and choosing the right automated tools for coverage. This guide gives you the full picture. WCAG
