Mobile app testing with unit tests, UI automation, performance testing. Use for test infrastructure, E2E tests, testing standards, or encountering test framework setup, device farms, flaky tests, platform-specific test errors.

Mobile App Testing

Implement comprehensive testing strategies for mobile applications.

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('[email protected]');
    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("[email protected]")
    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("[email protected]"))
    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

Keep looking

Skills are one crate of 328,083. Ordering is by how many stacks a row turns up in, so the top of any crate is what has actually been picked rather than what has the most stars.
