Mobile-specific test cases in Testing Fundamentals - Cheat Sheet & Quick Revision

Recall & Review

beginner

What are mobile-specific test cases?

Test cases designed to check features and behaviors unique to mobile devices, such as screen size, touch input, battery usage, and network conditions.

beginner

Why is testing on different screen sizes important in mobile testing?

Because mobile devices have various screen sizes and resolutions, testing ensures the app layout and content display correctly on all devices.

intermediate

Name a common network condition to test in mobile-specific test cases.

Testing under slow or unstable network conditions like 2G, 3G, or intermittent Wi-Fi to ensure the app handles connectivity issues gracefully.

intermediate

How do battery and power consumption relate to mobile testing?

Mobile apps should be tested to ensure they do not drain battery excessively, which affects user experience and device usability.

beginner

What is the importance of testing touch gestures in mobile apps?

Touch gestures like tap, swipe, pinch, and long press are primary ways users interact with mobile apps, so testing ensures these gestures work correctly and smoothly.

Which of the following is NOT a mobile-specific test case?

A Testing app behavior on different screen sizes

B Testing app response to keyboard shortcuts

C Testing app under various network conditions

D Testing battery consumption

Keyboard shortcuts are typically desktop-specific, not mobile-specific.

Why should mobile apps be tested for offline mode?

A To verify app functionality when no network is available

B To test app speed on fast networks

C To check if the app crashes without internet

D To check battery usage

Offline mode testing ensures the app works or handles lack of connectivity gracefully.

Which gesture is important to test in mobile apps?

A Hover

B Right click

C Double click

D Swipe

Swipe is a common touch gesture on mobile devices; right click and hover are desktop interactions.

What does testing app behavior during incoming calls check?

A App's ability to pause or resume correctly

B App's network speed

C App's battery usage

D App's screen resolution

Incoming calls can interrupt app usage; testing ensures the app pauses or resumes properly.

Which is a key reason to test mobile apps on different OS versions?

A To check app color scheme

B To verify keyboard shortcuts

C To ensure compatibility and functionality across OS versions

D To test desktop browser support

Different OS versions may affect app behavior; compatibility testing is essential.

List and explain three important mobile-specific test cases you would include when testing a new app.

Think about what makes mobile devices different from desktops.

Describe how you would test touch gestures in a mobile app and why it is important.

Imagine using the app with your fingers only.

Practice

1. Which of the following is a key focus when writing mobile-specific test cases?

easy

A. Testing only desktop browser compatibility

B. Testing features unique to mobile devices like GPS and touch gestures

C. Ignoring screen size variations

D. Testing only backend APIs without UI

Solution

1. Step 1: Understand mobile-specific features

   Mobile devices have unique features like GPS, accelerometer, and touch gestures that desktop devices do not.

2. Step 2: Identify test case focus

   Mobile-specific test cases must focus on these unique features to find device-specific issues.

3. Final Answer:

   Testing features unique to mobile devices like GPS and touch gestures -> Option B

4. Quick Check:

   Mobile features = A [OK]

Hint: Focus on device features unique to mobile devices [OK]

Common Mistakes:

• Ignoring mobile-only features
• Testing only desktop scenarios
• Not considering touch interactions

2. Which syntax correctly describes a test step for checking screen orientation change in a mobile test case?

easy

A. Step 1: Open browser and check URL

B. Step 1: Click desktop menu and verify dropdown

C. Step 1: Rotate device to landscape mode and verify UI adjusts correctly

D. Step 1: Run backend API and check response code

Solution

1. Step 1: Identify relevant mobile action

   Rotating device orientation is a common mobile-specific action to test UI responsiveness.

2. Step 2: Match test step syntax

   Step 1: Rotate device to landscape mode and verify UI adjusts correctly clearly states rotating device and verifying UI adjustment, which fits mobile test case syntax.

3. Final Answer:

   Step 1: Rotate device to landscape mode and verify UI adjusts correctly -> Option C

4. Quick Check:

   Mobile orientation test = B [OK]

Hint: Look for steps mentioning device rotation or orientation [OK]

Common Mistakes:

• Confusing desktop actions with mobile
• Ignoring device rotation in test steps
• Using backend steps in UI test cases

3. Consider this test step in a mobile app test case:

Step 1: Enable airplane mode
Step 2: Open the app
Step 3: Verify the app shows 'No internet connection'

What is the expected result of Step 3?

medium

A. App shows 'No internet connection' message

B. App logs user out automatically

C. App loads data from server normally

D. App crashes due to no network

Solution

1. Step 1: Analyze network condition

   Airplane mode disables all network connections, so the app cannot reach the internet.

2. Step 2: Understand expected app behavior

   The app should detect no internet and show a friendly message, not crash or load data.

3. Final Answer:

   App shows 'No internet connection' message -> Option A

4. Quick Check:

   Airplane mode disables network = D [OK]

Hint: No network means app shows offline message, not crash [OK]

Common Mistakes:

• Assuming app crashes without network
• Expecting normal data load offline
• Confusing logout with network loss

4. A tester wrote this mobile test step:

Step 1: Switch device to dark mode
Step 2: Open app
Step 3: Verify app UI uses dark colors

But the test always fails. What is the most likely error?

medium

A. The device was not actually switched to dark mode before testing

B. The app does not support dark mode at all

C. The tester used wrong device model

D. The app crashed on launch

Solution

1. Step 1: Check test setup correctness

   If the device is not switched to dark mode, the app UI won't change, causing test failure.

2. Step 2: Consider app support

   While app support matters, the question says test always fails, so setup is more likely the cause.

3. Final Answer:

   The device was not actually switched to dark mode before testing -> Option A

4. Quick Check:

   Incorrect setup causes test failure = A [OK]

Hint: Verify device mode before testing UI changes [OK]

Common Mistakes:

• Skipping device mode setup
• Assuming app supports dark mode without checking
• Ignoring device compatibility

5. You need to write a mobile-specific test case to verify the app's behavior when the device battery is low (below 15%). Which of the following is the best test step?

hard

A. Step 1: Connect device to chargerStep 2: Open appStep 3: Verify app loads data quickly

B. Step 1: Open appStep 2: Check if app crashes on startup

C. Step 1: Switch device to airplane modeStep 2: Open appStep 3: Verify app shows offline message

D. Step 1: Set device battery level to 10%Step 2: Open appStep 3: Verify app shows low battery warning and reduces background activity

Solution

1. Step 1: Simulate low battery condition

   Setting battery level below 15% tests app behavior under low power.

2. Step 2: Verify app response

   The app should warn user and reduce background tasks to save battery.

3. Final Answer:

   Step 1: Set device battery level to 10%
   Step 2: Open app
   Step 3: Verify app shows low battery warning and reduces background activity -> Option D

4. Quick Check:

   Low battery test = C [OK]

Hint: Simulate battery level, check app warning and behavior [OK]

Common Mistakes:

• Testing unrelated conditions
• Ignoring battery level simulation
• Confusing network and battery tests
