Identify the type of mobile testing

Which type of mobile testing focuses on verifying the app's behavior on different network conditions like 3G, 4G, and Wi-Fi?

A Performance Testing

B Usability Testing

C Network Testing

D Compatibility Testing

💡 Hint

Think about testing how the app works with different internet connections.

Network Testing checks how the mobile app performs under various network conditions such as 3G, 4G, Wi-Fi, or poor connectivity.

❓ Predict Output

Output of test result for battery usage check

Given a test script that measures battery consumption of a mobile app, what is the expected output if the app uses 15% battery in 1 hour, exceeding the 10% limit?

Testing Fundamentals

battery_usage = 15
limit = 10
result = 'Pass' if battery_usage <= limit else 'Fail'
print(result)

A 15

B Error

C Pass

D Fail

💡 Hint

Check if battery usage is within the allowed limit.

Since 15% is greater than the 10% limit, the test result is 'Fail'.

❓ assertion

Correct assertion for screen orientation test

Which assertion correctly verifies that the mobile app screen orientation changed to landscape mode?

Testing Fundamentals

current_orientation = get_screen_orientation()  # returns 'portrait' or 'landscape'

A assert current_orientation = 'landscape'

B assert current_orientation == 'landscape'

C assert current_orientation != 'portrait'

D assert current_orientation is 'landscape'

💡 Hint

Use the correct equality operator in assertions.

Option B uses the correct equality operator '==' to check if orientation is 'landscape'. Option B uses assignment '=' which is invalid in assert. Option B only checks not portrait but could be other values. Option B uses 'is' which is not recommended for string comparison.

Find the bug in this mobile app test locator

This locator is used to find a button by accessibility id in a mobile app test. What is the bug?

Testing Fundamentals

button = driver.find_element_by_accessibility_id('submitBtn')

A Method find_element_by_accessibility_id is deprecated, should use find_element('accessibility id', 'submitBtn')

B No bug, code is correct

C Accessibility id should be 'submit_btn' with underscore

D Should use find_element_by_id instead

💡 Hint

Check if the method used is current in modern mobile testing frameworks.

The method find_element_by_accessibility_id is deprecated in recent versions. The correct usage is find_element with locator strategy 'accessibility id'.

Choosing the best mobile testing framework for cross-platform automation

Which mobile testing framework supports both Android and iOS automation using a single API and is widely used for cross-platform testing?

A Appium

B XCUITest

C Espresso

D Robotium

💡 Hint

Look for a framework that works on both Android and iOS.

Appium supports both Android and iOS automation with a single API, making it ideal for cross-platform mobile testing. Espresso is Android-only, XCUITest is iOS-only, and Robotium is Android-only.
