5. Descriptive Notes / Programs

A. Native vs Hybrid vs Mobile Web Apps

Native Apps: Developed using platform-specific SDKs (e.g., Android Studio for Android, Xcode for iOS). Best performance but higher cost.
Hybrid Apps: Combination of native and web; use frameworks like Ionic, React Native. Portable but slower.
Mobile Web Apps: Browser-based, accessed via URLs. Cost-effective but limited access to device features.

B. Key Difference: Emulator vs Simulator

Feature	Emulator (Android)	Simulator (iOS)
Mimics	Hardware + Software	Software only
Performance	Slower (since it mimics hardware too)	Faster
Accuracy	High (close to real device)	Limited (no hardware replication)
Example	Android Emulator	iOS Simulator

C. Mobile Testing Tools (Planning & Execution)

Appium → Cross-platform testing tool (Android + iOS).
Espresso → Google’s framework for Android UI testing.
XCTest → Apple’s framework for iOS testing.
Robotium → Open-source framework for Android.
Selendroid → For Android automation.

D. Hardware Perspective in Mobile Testing

Screen sizes & resolutions
Battery usage & performance
Memory and storage
Network conditions (WiFi, 3G, 4G, 5G)
Sensors (GPS, Camera, Accelerometer)

E. Example – UI Test in Espresso (Android)

@Test

public void testLoginButton() {

onView(withId(R.id.login_button))

.perform(click());

onView(withId(R.id.welcome_message))

.check(matches(withText("Welcome User!")));

}

F. Example – UI Test in XCTest (iOS)

func testLoginButton() {

let app = XCUIApplication()

app.buttons["login_button"].tap()

XCTAssert(app.staticTexts["Welcome User!"].exists)

}
