Mobile Testing Frameworks Skill
Overview
This skill provides comprehensive expertise in mobile testing frameworks across platforms. It enables E2E testing with Detox and Maestro, native testing with XCUITest and Espresso, and cross-platform testing with Appium.
Allowed Tools
bash - Execute test commands and framework CLIs
read - Analyze test files and configurations
write - Generate test cases and configurations
edit - Update existing tests
glob - Search for test files
grep - Search for patterns in test code

Detox (React Native)
-
Configuration
- Set up Detox configurations
- Configure iOS and Android builds
- Set up device/simulator targets
- Configure test runners (Jest)
-
Test Writing

- Implement actions (tap, type, scroll)
- Configure expectations
- Handle synchronization
-
Advanced Features
- Mock native modules
- Handle permissions
- Configure network mocking
- Implement visual regression

beforeEach(async () => {
await device.reloadReactNative();
});
it('should show login screen on first launch', async () => {
await expect(element(by.id('login-screen'))).toBeVisible();
await expect(element(by.id('email-input'))).toBeVisible();
await expect(element(by.id('password-input'))).toBeVisible();
});
it('should show error for invalid credentials', async () => {

(by.()).();
(by.()).();
((by.())).();
