wtf is android-testing-skills?

Android Testing Skills is a collection of 54 instruction files, called skills, that teach AI coding agents like Claude Code, Android Studio Agent mode, or Gemini how to write different kinds of Android tests. Each skill covers one focused topic and is grounded in real Android source code or official documentation rather than guesswork, so the instructions can also be read by a human who wants a reference. The skills are grouped into seven sets. The largest set covers testing Jetpack Compose user interfaces, including finding elements on screen, checking their state, and simulating gestures. Other sets cover testing fundamentals like what to test and how to structure test files, plain JVM unit tests using tools like Mockito and Robolectric, on-device instrumentation tests, migrating away from older deprecated Android test classes, and driving end-to-end tests through ADB, the Android command line tool, for things like installing apps, capturing screenshots, and reading logs. A skill itself is a single markdown file that declares when it should be used and lays out a numbered set of steps for an agent to follow, written in a direct, instructional style rather than as a human tutorial. You do not need every skill in the collection. You pick the sets that match what your project actually tests, for example the Compose set if you write Compose UI tests or the ADB set if you script tests in continuous integration. Because the agent tools expect a flat folder of skills, while this repository organizes them into nested category folders for readability, installing requires running a bundled script that creates the right symlinks after cloning. The project is released under the Apache 2.0 license.
