Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/secondsky/claude-skills --skill mobile-app-testing- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads mobile-app-testing automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
Mobile App Testing
Implement comprehensive testing strategies for mobile applications.
Testing Pyramid
| Level | Tools | Coverage |
|---|---|---|
| Unit | Jest, XCTest, JUnit | 70% |
| Integration | Detox, Espresso | 20% |
| E2E | Appium, Detox | 10% |
React Native (Jest + Detox)
// Unit test
describe('CartService', () => {
it('calculates total correctly', () => {
const cart = new CartService();
cart.addItem({ price: 10, quantity: 2 });
expect(cart.getTotal()).toBe(20);
});
});
// E2E test (Detox)
describe('Login flow', () => {
beforeEach(async () => {
await device.reloadReactNative();
});
it('should login successfully', async () => {
await element(by.id('email-input')).typeText('user@example.com');
await element(by.id('password-input')).typeText('password123');
await element(by.id('login-button')).tap();
await expect(element(by.id('dashboard'))).toBeVisible();
});
});
iOS (XCTest)
func testLoginSuccess() {
let app = XCUIApplication()
app.launch()
app.textFields["email"].tap()
app.textFields["email"].typeText("user@example.com")
app.secureTextFields["password"].typeText("password123")
app.buttons["Login"].tap()
XCTAssertTrue(app.staticTexts["Welcome"].exists)
}
Android (Espresso)
@Test
fun loginSuccess() {
onView(withId(R.id.email)).perform(typeText("user@example.com"))
onView(withId(R.id.password)).perform(typeText("password123"))
onView(withId(R.id.loginButton)).perform(click())
onView(withId(R.id.dashboard)).check(matches(isDisplayed()))
}
Best Practices
- Test business logic first (unit tests)
- Mock external dependencies
- Test both success and failure paths
- Automate critical user flows
- Maintain >80% code coverage
- Test on real devices periodically
Avoid
- Testing implementation details
- Hardcoded test data
- Interdependent tests
- Skipping error case testing
