Accessibility Snapshot Testing in iOS

Accessibility snapshot testing extends traditional visual snapshot testing by capturing the semantic accessibility hierarchy—labels, traits, hints, and element order—rather than pixels. The AccessibilitySnapshot library by CashApp integrates with the SnapshotTesting framework, enabling developers to detect accessibility regressions such as renamed labels or missing traits early in automated test suites. This approach provides clear, readable output of the accessibility structure without requiring manual screen reader inspection.
