Accessibility Test Framework for Android vs GitHub CodeQL

Accessibility Test Framework for Android is a free, Apache-2.0-licensed library for automated accessibility checks in Android app testing. It checks Android View and AccessibilityNodeInfo objects, with missing contentDescription given as an example of an issue automated tools can detect. A sample runs checks across the view hierarchy beneath a chosen view using the latest check preset, and throws an exception when it finds errors. The project includes a Gradle wrapper and build.gradle file and can be imported into Android Studio. It is intended for developers who want to check how their apps are presented to accessibility services. Automated checks cannot settle every accessibility question: whether a content description makes sense to users, for example, requires human judgment. The framework is hosted in Google’s public GitHub organization. Although the platform listing includes Android alongside desktop operating systems, the stated purpose and checks are specifically for Android app accessibility testing.
