Testing
Integrating accessibility testing into CI/CD means every code change is automatically checked for WCAG violations before it reaches production. This prevents accessibility regressions — where a change that broke accessible behavior slips through unnoticed. This guide covers how to set up automated accessibility checks in GitHub Actions, what tools to
Testing
Screen reader testing is one of the most direct ways to verify that your application is accessible to blind and low-vision users.
Testing
axe-core is the accessibility testing engine behind Deque's browser extensions, most CI accessibility tools, and the built-in accessibility checks in browser DevTools. Understanding how to use it directly gives you more control over what you test, what you suppress, and how violations surface in your build
Testing
Playwright's browser automation and axe-core's accessibility engine are a natural pairing. Playwright handles navigation, interaction, and state management.
Testing
Accessibility compliance is not a checkbox. Running an automated scanner and calling it done leaves the majority of real accessibility barriers undetected.
Testing
Catching accessibility regressions in CI is straightforward once you pick the right tools and decide what to block on.
Testing
shadcn/ui is not a component library you install — it's a collection of components you copy into your codebase, built on Radix UI primitives and styled with Tailwind CSS. Because you own the source code, testing shadcn/ui components means testing your actual components, not a third-party
Testing
Radix UI provides unstyled, accessible React primitives that handle complex interaction patterns — keyboard navigation, focus management, ARIA attributes — so you don't have to. Testing Radix UI components effectively means verifying these accessibility behaviors work in your application context, while also validating your custom logic and styling don'
Testing
Headless component libraries — shadcn/ui, Radix UI, Headless UI, Ark UI — are built with accessibility as a core feature.
Testing
React Native gives you one codebase that runs on iOS and Android, but accessibility is one area where the platforms diverge significantly.

Roughly 1 in 6 people worldwide lives with some form of disability, and on mobile, screen readers like VoiceOver are often the only viable navigation method.

Android's TalkBack screen reader serves millions of users who depend on it for daily app interaction.
