Gesture Testing Using ADB Commands Notes By ShariqSP

Gesture Testing Using ADB Commands

1. Setting Up ADB for Gesture Testing

ADB (Android Debug Bridge) allows you to simulate gestures for testing on Android devices. Before proceeding, ensure ADB is installed and your device is connected with USB debugging enabled.

1. Install ADB as explained in the location testing setup.
2. Verify the connection using:

   adb devices

3. Enable developer options and ensure USB debugging is turned on.

2. Simulating Swipe Gestures

Swipe gestures are essential for testing navigation and other interactions. Use the following commands to simulate various swipe gestures:

• Swipe Up:

  adb shell input swipe 500 1500 500 500

  • This simulates a swipe from the bottom (Y=1500) to the top (Y=500) of the screen.
• Swipe Down:

  adb shell input swipe 500 500 500 1500

  • This simulates a swipe from the top (Y=500) to the bottom (Y=1500) of the screen.
• Swipe Right:

  adb shell input swipe 200 1000 800 1000

  • This simulates a swipe from the left (X=200) to the right (X=800) of the screen.
• Swipe Left:

  adb shell input swipe 800 1000 200 1000

  • This simulates a swipe from the right (X=800) to the left (X=200) of the screen.

3. Simulating Two-Finger Gestures

Two-finger gestures are commonly used for zooming or tapping on elements. ADB can simulate this using multi-touch events:

• Two-Finger Tap:

  adb shell input touchscreen swipe 300 800 300 800 200; adb shell input touchscreen swipe 600 800 600 800 200

  • This simulates two fingers tapping on the screen at positions (300, 800) and (600, 800).
• Pinch Zoom In:

  
                adb shell input touchscreen swipe 300 800 300 600 300 && adb shell input touchscreen swipe 600 800 600 1000 300
                

  • This simulates a pinch zoom-in gesture, with two fingers moving closer.
• Pinch Zoom Out:

  
                adb shell input touchscreen swipe 300 600 300 800 300 && adb shell input touchscreen swipe 600 1000 600 800 300
                

  • This simulates a pinch zoom-out gesture, with two fingers moving apart.

4. Simulating Three-Finger Gestures

Three-finger gestures are less common but can be tested using ADB's multi-touch swipe command:

• Three-Finger Swipe Down:

  
                adb shell input touchscreen swipe 300 500 300 1500 300; adb shell input touchscreen swipe 500 500 500 1500 300; adb shell input touchscreen swipe 700 500 700 1500 300
                

  • This simulates a three-finger swipe down on the screen.
• Three-Finger Swipe Up:

  
                adb shell input touchscreen swipe 300 1500 300 500 300; adb shell input touchscreen swipe 500 1500 500 500 300; adb shell input touchscreen swipe 700 1500 700 500 300
                

  • This simulates a three-finger swipe up on the screen.

5. Testing Gestures on Specific UI Elements

To target specific elements, determine their coordinates using UI debugging tools or screenshots. Then, simulate taps or gestures:

• Tap on an Element:

  adb shell input tap 400 600

  • This taps the element located at (400, 600).
• Double Tap:

  adb shell input tap 400 600; adb shell input tap 400 600

  • This simulates a double-tap on the element at (400, 600).

6. Practical Testing Scenarios

Gesture testing is critical for validating user experiences in mobile apps. Here are some scenarios:

• Scroll Testing: Use swipe gestures to test infinite scrolling in news or e-commerce apps.
• Zoom Testing: Simulate pinch gestures to test map interactions in apps like Google Maps or Ola.
• Multi-Touch: Test two-finger taps for gestures in drawing or note-taking apps.
• Navigation Testing: Test swipe gestures for app navigation, such as swiping between pages or closing menus.

ADB commands provide a robust way to automate and simulate gestures, enabling comprehensive testing of mobile applications.
