Dynamic Accessibility Analysis

An approach to detecting accessibility issues by testing an application while it is running on a device or emulator, examining the actual rendered user interface rather than just the source code. Tools like Google's Accessibility Scanner perform dynamic analysis by evaluating each screen of an app against accessibility guidelines, checking actual rendered color contrast, touch target sizes, content descriptions, and interactive element behavior. Dynamic analysis can detect issues that static analysis misses, such as problems arising from dynamic content generation, screen composition, or runtime styling. However, it requires human interaction or automated scripts to navigate to each screen, making it more time-consuming and resource-intensive than static analysis.
