Mobile App Interview Questions and Answers
Question - 51 : - What are the essential things to remember while testing apps using the Black Box testing method?
Answer - 51 : -
- The application’s compatibility with multiple devices
- The device’s proper connection and disconnection while changing the IP or port address
- The capability to make calls and send messages to other devices
- The compatibility with multiple browsers (Chrome, Firefox, Opera, etc.)
Question - 52 : - How many types of automation testing tools are available for mobile devices?
Answer - 52 : -
For mobile testing, there are two types of automation testing tools: object-based or image-based tools.
Question - 53 : - List out the types of mobile app testing
Answer - 53 : -
- Usability Testing
- Compatibility Testing
- Interface Testing
- Services Testing
- Low-level resource Testing
- Performance Testing
- Operational Testing
- Installation Testing
- Security Testing
Answer - 54 : -
Similar to the plan of other application under tests, a plan designed for automated mobile application testing should include:
- Testing scope and objectives
- Selected automation tool
- Required features to be tested:
– Performance
– Security
– Network
– Size
– Battery memory
- Test cases
- Test strategy
- Person in charge
- Time frame
- Resources required
For further test automation strategies and best practices, please have a glimpse into the Automated Tester’s Checklist and consider which strategies are best suited to your team.
Question - 55 : - When performing a sanity test on the mobile application, what criteria should be included?
Answer - 55 : -
- Installation and uninstallation of the application
- Performance in different available networks: 2G, 3G, 4G, 5G, or WIFI.
- Functional testing
- Interrupt testing
- Compatibility testing
- Application performance on other handsets
- The behavior of the application when entering invalid credentials
Question - 56 : - Explain how A/B testing is done for the iOS app?
Answer - 56 : -
The A/B testing for iOS can be done through three steps:
- Step 1: Configuring a test that prepares two versions of your iOS application (A&B) with required test metrics
- Step 2: Testing both of the iOS versions above on devices simultaneously
- Step 3: Analyzing the test results to measure and select which will be the better version to release
Question - 57 : - When should a QA team choose manual testing or automation testing for their mobile test projects?
Answer - 57 : -
Automation testing has vastly increased testers’ speed and quality in the past decades. Understanding when to make such a transition, from manual testing to automated testing, is the first step to maximizing your team’s efficiency. Here are some of the critical points:
Manual Testing
- The application has new functionality.
- The application requires testing once or twice.
Automate Testing
- The release cycle needs a large amount of regression testing.
- The testing application requires complex scenarios.
Question - 58 : - List of the most common problem that testers face while doing mobile testing on Cloud Computing
Answer - 58 : -
Executing mobile testing in Cloud Computing poses various challenges for both beginners and advanced testers.
Subscription model:
Even though Cloud solution offers testers a couple of advantages, there is a persistent concern about the subscription model.
High costs:
While Cloud services have been sold as cost-savings solutions, the reality is that these services can be more expensive. The challenge can arise from the cost of the talent needed, the migration process to the team’s mobile testing project.
Difficulties in mobile automated testing:
As for some projects applying automated testing, Cloud computing may come with a pain point for every tester involved. Because mobile automation testing is image-based, executing test cases on Cloud computing would become more challenging and time-consuming. Moreover, automation testing cannot be used outside the framework.
Question - 59 : - What is an Android testing framework?
Answer - 59 : -
One of the most standard testing frameworks for Android applications is the Android testing framework. It is comprised of three segments:
Application Package
- It is the target application that requires to be tested.
Instrumentation Test Runner
- This part of the framework serves as a Test Case Runner, allowing test cases to run on the target application. It includes two parts: an SDK tool for building test; and a tool that provides APIs for writing program which controls an Android device or an emulator outside of Android codes (i.e., MonkeyRunner)
Test Package
- It consists of two components: Test case classes and Mock objects. Test case classes constitute test methods to perform the on-target application, while mock objects include mock data used as sample input for test cases.
Question - 60 : - What is a Robolectric testing framework?
Answer - 60 : -
Testing applying the Android Testing framework with a device or an emulator is challenging. It takes the team’s tremendous development effort and time in building and running tests. And the Robolectric testing framework is considered as a solution to address this challenge.
Robolectric framework allows testers to run Android tests directly on JVM (Java Virtual Machine) without a device or an emulator’s need.
