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.
```
adb
```
installed 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.

bash

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).

bash

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.

bash

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.

bash

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 make
```
grep
```
verification easy.
Fail Fast: If a
```
uiautomator dump
```
fails or doesn't find the expected text, stop and troubleshoot rather than blind-tapping.
