5. Appium Server
6. Android device or emulator / iOS device or simulator

Setup

1. Install dependencies:

npm install

2. Install and start Appium server:

appium

3. Set up Android device/emulator:
   • Enable Developer Options on your Android device
   • Enable USB Debugging
   • Connect device via USB or start an emulator
   • Verify device is connected using adb devices

Running Tests

1. Build the project:

npm run build

2. Start the MCP server:

npm run dev

3. In a new terminal, run the test:

npm test

Test Configuration

The example test uses the Android Settings app as a demo. To test your own app:

1. Edit examples/appium-test.ts:

   • Update deviceName to match your device
   • Set app path to your APK file, or
   • Update appPackage and appActivity for an installed app

2. Common capabilities configuration:

const capabilities: AppiumCapabilities = {
    platformName: 'Android',
    deviceName: 'YOUR_DEVICE_NAME',
    automationName: 'UiAutomator2',
    // For installing and testing an APK:
    app: './path/to/your/app.apk',
    // OR for testing an installed app:
    appPackage: 'your.app.package',
    appActivity: '.MainActivity',
    noReset: true
};

   • Custom gestures

Troubleshooting

1. Device not found:

   • Check adb devices output
   • Verify USB debugging is enabled
