Mobile App Tester

Overview

Execute automated mobile application testing on iOS simulators and Android emulators covering UI interactions, navigation flows, gesture handling, and platform-specific behaviors. Supports Appium, Detox (React Native), XCUITest (iOS native), Espresso (Android native), and Maestro for cross-platform mobile testing.

Prerequisites

• Mobile testing framework installed (Appium, Detox, Maestro, or native XCUITest/Espresso)
• iOS Simulator via Xcode (macOS only) or Android Emulator via Android SDK
• Application build artifact (.app, .apk, or .ipa) or bundled dev server (React Native)
• Appium drivers installed (uiautomator2 for Android, xcuitest for iOS) if using Appium
• Node.js for JavaScript-based test runners

Instructions

1. Configure the test environment:
   • List target devices/simulators: specify OS versions, screen sizes, and orientations.
   • Build the application for testing (xcodebuild, ./gradlew assembleDebug, or npx react-native build).
   • Start the emulator/simulator or connect physical devices.
   • Install the app on the target device.
2. Create test cases for core mobile interactions:
   • Tap and navigation: Tap buttons, navigate between screens, verify back navigation.
   • Text input: Fill forms, verify keyboard behavior, test autocomplete and paste.
   • Scrolling: Scroll lists, verify lazy loading, test pull-to-refresh.
   • Gestures: Swipe (carousel), pinch-to-zoom, long press, drag-and-drop.
   • System interactions: Handle permission dialogs, push notifications, deep links.
3. Test platform-specific behaviors:
   • iOS: Safe area insets, notch handling, Dynamic Type, VoiceOver accessibility.
   • Android: Back button behavior, multi-window, different navigation patterns, TalkBack.
   • Both: Screen rotation (portrait/landscape), dark mode, low battery mode.
4. Implement device-specific test configurations:
   • Define capability sets for each device/OS combination.
   • Use test tagging to run subsets on specific platforms (@ios, @android).
   • Configure screenshot capture on failure for visual debugging.
5. Handle asynchronous mobile behaviors:
   • Wait for animations to complete before assertions.
   • Handle network loading spinners with explicit waits.
   • Account for system dialogs (permissions, updates) that interrupt test flow.
6. Run the test suite and capture results:
   • Execute tests per platform: npx detox test --configuration ios.sim.debug.
   • Collect device logs, screenshots, and crash reports.
   • Generate JUnit XML or Allure reports for CI integration.
7. Set up CI pipeline for mobile testing (GitHub Actions macOS runners for iOS, Linux for Android).

Output

• Mobile test files organized by feature/flow in tests/mobile/ or e2e/
• Device configuration profiles for each target device/OS combination
• Screenshot captures for visual validation and failure debugging
• Test results in JUnit XML format with device-specific metadata
• CI pipeline configuration for automated mobile test execution

Error Handling

Examples

Detox test for React Native login flow:

describe('Login Flow', () => {
  beforeAll(async () => { await device.launchApp(); });
  beforeEach(async () => { await device.reloadReactNative(); });

  it('logs in with valid credentials', async () => {
    await element(by.id('email-input')).typeText('user@test.com');
    await element(by.id('password-input')).typeText('password123');
    await element(by.id('login-button')).tap();
    await expect(element(by.id('home-screen'))).toBeVisible();
  });
});

Maestro flow file:

appId: com.example.myapp
---
- launchApp
- tapOn: "Sign In"
- inputText:
    id: "email-input"
    text: "user@test.com"
- inputText:
    id: "password-input"
    text: "password123"
- tapOn: "Submit"
- assertVisible: "Welcome"
