Android UI Verification Skill
This skill provides a systematic approach to testing React Native applications on an Android emulator using ADB commands. It allows for autonomous interaction, state verification, and visual regression checking.
When to Use
- Verifying UI changes in React Native or Native Android apps.
- Autonomous debugging of layout issues or interaction bugs.
- Ensuring feature functionality when manual testing is too slow.
- Capturing automated screenshots for PR documentation.
🛠 Prerequisites
- Android Emulator running.
adbinstalled and in PATH.- Application in debug mode for logcat access.
🚀 Workflow
1. Device Calibration
Before interacting, always verify the screen resolution to ensure tap coordinates are accurate.
adb shell wm size
Note: Layouts are often scaled. Use the physical size returned as the base for coordinate calculations.
2. UI Inspection (State Discovery)
Use the uiautomator dump to find the exact bounds of UI elements (buttons, inputs).
adb shell uiautomator dump /sdcard/view.xml && adb pull /sdcard/view.xml ./artifacts/view.xml
Search the view.xml for text, content-desc, or resource-id. The bounds attribute [x1,y1][x2,y2] defines the clickable area.
3. Interaction Commands
- Tap:
adb shell input tap <x> <y>(Use the center of the element bounds). - Swipe:
adb shell input swipe <x1> <y1> <x2> <y2> <duration_ms>(Used for scrolling). - Text Input:
adb shell input text "<message>"(Note: Limited support for special characters). - Key Events:
adb shell input keyevent <code_id>(e.g., 66 for Enter).
4. Verification & Reporting
Visual Verification
Capture a screenshot after interaction to confirm UI changes.
adb shell screencap -p /sdcard/screen.png && adb pull /sdcard/screen.png ./artifacts/test_result.png
Analytical Verification
Monitor the JS console logs in real-time to detect errors or log successes.
adb logcat -d | grep "ReactNativeJS" | tail -n 20
Cleanup
Always store generated files in the artifacts/ folder to satisfy project organization rules.
💡 Best Practices
- Wait for Animations: Always add a short sleep (e.g., 1-2s) between interaction and verification.
- Center Taps: Calculate the arithmetic mean of
[x1,y1][x2,y2]for the most reliable tap target. - Log Markers: Use distinct log messages in the code (e.g.,
✅ Action Successful) to makegrepverification easy. - Fail Fast: If a
uiautomator dumpfails or doesn't find the expected text, stop and troubleshoot rather than blind-tapping.
