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.
Testing
Catching accessibility regressions in CI is straightforward once you pick the right tools and decide what to block on. The challenge is not technical — it's deciding your enforcement strategy: block on any violation, block on regressions from baseline, or track and report without blocking. This guide covers the
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. But "accessible by design" doesn't mean "accessible by default in your application." Your composition, custom styles, and application logic can break the accessibility guarantees these
Testing
React Native's cross-platform model means accessibility bugs can appear on iOS, Android, or both, often in different forms. A layered testing approach — jest-native for component tests, react-native-axe-core for runtime audits, and Detox for end-to-end screen reader behavior — catches issues at every
Testing
VoiceOver is the primary screen reader on iOS, and testing it manually doesn't scale. XCTest's accessibility audit APIs let you catch labeling gaps, broken focus order, and trait mismatches in CI before they reach real users. This guide covers the full automation stack from XCUIAccessibility queries
Testing
TalkBack is Android's built-in screen reader, and testing it manually doesn't scale across a large test suite. Espresso's AccessibilityChecks API, the Accessibility Test Framework, and Robolectric together give you a layered approach to catching accessibility regressions in CI before they reach users. Android&
Testing
axe-core is the most widely deployed accessibility rules engine in the world, and it works inside Appium test suites — not just on the web. By injecting axe-core into WebView contexts within hybrid and cross-platform apps, you can run the same accessibility rules in your mobile CI pipeline
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
Testing
Voice UI quality requires testing across five dimensions: NLU intent recognition accuracy (precision/recall/F1), multi-turn dialog flow completeness, slot filling edge cases and error recovery, accessibility compliance for voice, and cross-platform consistency across Alexa, Google, and Siri. This guide defines the test matrix and KPIs for each
Testing
WCAG 2.1 — the Web Content Accessibility Guidelines, version 2.1 — is the international standard for web accessibility. Published by the W3C in 2018, it defines how to make web content accessible to people with disabilities. For developers, the challenge isn't understanding the principles (they're sensible)
