Answer: Common challenges include handling various operating systems, testing on a wide range of devices, dealing with screen size fragmentation, ensuring compatibility across different mobile networks, and selecting the right testing tools.
7. What types of mobile testing should be included in the Android testing strategy?
Answer: An Android testing strategy should include unit testing, system testing, integration testing, and operation testing, tailored to the specific features of the application.
8. What is the strategy used to test a new mobile app? Which types of testing should be included?
Answer: A comprehensive test strategy for a new mobile app includes selecting appropriate devices, utilizing emulators for initial testing, and conducting various types of testing such as functional, system integration, performance, and compatibility testing to ensure the app performs well under different conditions.
9. What does an automated test plan for Mobile App contain?
Answer: An automated test plan should outline the testing scope and objectives, select the appropriate automation tools, define features to be tested (e.g., performance, security), detail test cases and strategies, assign responsibilities, set a timeframe, and allocate necessary resources.
10. List the best practices for Android Testing.
Answer:
– Develop test cases concurrently with code development.
– Maintain well-documented and reusable test cases.
– Implement continuous integration to run tests with every code change.
– Use non-rooted devices and real emulators for reliable results.
11. What primary criteria should be considered while planning end-to-end mobile testing?
Answer: Key criteria include ensuring the app installs successfully across various devices and operating systems, launches smoothly with or without a network, supports multiple orientations, performs well under different network conditions, and responds efficiently to user interactions.
12. What is the difference between simulators and emulators?
Answer: Simulators mimic the internal behavior of a device without replicating hardware, while emulators replicate both hardware and software features. Emulators are generally more suitable for debugging purposes.
13. How to test CPU usage on mobile devices?
Answer: Utilize tools available on Google Play or the App Store, such as CPU Monitor or CPU-Z, which record and analyze CPU usage and performance metrics on mobile devices.
14. What are the major networks to consider while performing application testing?
Answer: Testing should cover 2G, 3G, 4G, 5G, and Wi-Fi networks to ensure the application performs optimally under different network conditions.
15. What criteria should be included in a sanity test for a mobile application?
Answer: Sanity testing should include installation and uninstallation processes, performance across different networks, functionality checks, interrupt testing, compatibility testing, and responsiveness with invalid inputs.
16. What is the best way to test different screen sizes of devices?
Answer: Using emulators is the most effective method for testing applications across various screen sizes, allowing testers to simulate different device dimensions without needing physical devices.
17. What are the common bugs found during mobile testing?
Answer: Common bugs include critical bugs that cause OS crashes, block bugs that prevent app functionality, major bugs affecting specific features, and minor bugs related to the graphical user interface (GUI).
18. Explain how A/B testing is done for an iOS app.
Answer: A/B testing for iOS involves creating two versions of the app with different features or designs, testing both versions on devices simultaneously, and analyzing the results to determine which version performs better based on predefined metrics.
19. When should a QA team choose manual testing over automation testing?
Answer: Manual testing is preferred when the app has new functionalities, requires one-time testing, or involves complex scenarios that are difficult to automate. Automation testing is ideal for large regression testing cycles and repetitive tasks.
20. What are the common problems testers face while doing mobile testing on Cloud Computing?
Answer: Challenges include high costs, subscription model limitations, and difficulties in executing image-based automated tests on cloud platforms, which can be time-consuming and complex.
21. What should be remembered while testing apps using the Black Box testing method?
Answer: Ensure compatibility with multiple devices, maintain proper device connections, verify the ability to make calls and send messages, and test across different browsers to ascertain the app’s functionality from an end-user perspective.
22. What is an Android testing framework?
Answer: The Android testing framework comprises the application package, instrumentation test runner, and test package. It facilitates running test cases on target applications using tools like MonkeyRunner and provides APIs for controlling devices or emulators.
