Making iOS Accessibility Testing Easy
Article Summary
Cash App's engineering team just open-sourced their solution to one of iOS development's most frustrating problems: testing accessibility without the manual grind.
Traditional accessibility testing on iOS is broken. Unit tests give false positives, UI tests don't reflect real user behavior, and manual testing is inconsistent. Cash App built AccessibilitySnapshot to fix this with snapshot testing principles.
Key Takeaways
- AccessibilitySnapshot generates visual snapshots showing exactly how VoiceOver reads your UI
- Catches accessibility regressions immediately in your existing test suite
- Supports Invert Colors and Dynamic Type, not just VoiceOver
- Open source framework requires just one line of code to implement
Critical Insight
Cash App turned accessibility testing from a manual, time-consuming process into automated snapshot tests that catch regressions before they ship.
