Top Mobile App Testing Interview Questions

Q1 What do you mean by mobile application testing in digital era?

The practice of evaluating a mobile application to guarantee its consistency, usability, and operation is known as mobile application testing. Mobile application testing may be done by testers manually or automatically.

Q2 What makes mobile app testing vital for a business?

Testing is an indispensable part of every software development process. Mobile application is no exception: the growing number of mobile devices gives rise to massive operation system fragmentation, screen sizes, and more. That is why QA teams make tremendous attempts to ensure the user’s seamless experience across various mobile devices without functionality bugs and issues. 

By putting the mobile application through rigorous testing, Mobile App Testing Interview Questions the product team can enhance the app’s ratings, as well as customer satisfaction, for valuable referrals for even more downloads.

Q3 How do you distinguish mobile device testing from mobile app testing?

Mobile device testing verifies the hardware and software capabilities of a device to assess its quality. Features like the screen, memory, camera and apps are tested throughout this procedure. Additionally, it includes certification testing and manufacturing testing.

On the other hand, mobile application testing entails evaluating the mobile application’s consistency and functioning across a range of mobile devices. Following this procedure, you may assess the quality of the intended application to see if it is compatible with the device in terms of hardware, software, network connectivity, etc.

Q4 What are the different types of mobile applications?

Mobile applications fall into three types.

  • Native application:- A software program created in a particular programming language specifically for the iOS or Android mobile platform is referred to as a native application. It is available in the app shop (App Store for iOS and Google Play for Android) and can be easily installed on your devices, like Facebook or WhatsApp.
  • Web application:- Using a mobile network or WiFi, a web application runs inside a mobile web browser, such as Chrome, Firefox, Opera, or Safari. Web apps like,, etc., are just a few examples.
  • Hybrid application:- A hybrid application combines features from both native and web applications. It is a web app created using HTML, CSS, or JavaScript that runs in a web view, despite the fact that it may be installed on a device much like a native app.

Q5 What are the different aspects of mobile app testing?

  • Installation Testing
  • Interface Testing
  • Low-level resource Testing
  • Security Testing
  • Operational Testing
  • Usability Testing
  • Performance Testing
  • Compatibility Testing
  • Services Testing

Q6 What are the typical challenges a mobile app tester usually faces?

  • Running test cases on different operating systems
  • Testing the features of a program on several mobile devices
  • Fragmentation due to screen size
  • Testing software on various mobile networks
  • Different methods of testing are needed depending on the kind of application (native, hybrid, or web app).
  • The QA team’s decision on the best mobile testing tool

Q7 Which mobile testing categories ought to be covered by the Android testing strategy?

Subject to the functionality offered by the mobile application being tested, a typical Android strategy may comprise these testing types: unit testing, system testing, integration testing, and operation testing. Depending on the features of the application, further tests may also be carried out if necessary.

Q8 Which strategy is used to test a new mobile application?

For a new mobile application to run successfully, a thorough test strategy should be designed based on specified criteria. The following are some of the key points:

  1. Device selection – Before picking a set of testing devices, it is strongly advised to understand the market’s need and the regularly utilized equipment. Mobile App Testing Interview Questions The stakeholders or the app developers may also influence this decision.
  2. Use of emulators Since they enable speedy app testing, emulators are helpful, especially in the early stages of development. It is a technology that allows the software to be operated in different environments without requiring the software to be changed. Additionally, it operates on the actual system and mimics the functionalities.

Q9 What kind of tests should be run on a new mobile application?

  • Gateway testing
  • Testing multiple mobile OS
  • Installation and uninstallation of the application
  • Cross-browser and cross-device testing
  • System integration testing
  • Functional testing
  • HTML control testing
  • Performance testing
  • Network and battery testing

Q10 Name the best practices used for android testing?

  • When simultaneously creating programs, developers need to write test cases.
  • For reuse, each test case has to be saved and thoroughly documented.
  • After a code update, use continuous integration and run the tests.
  • To obtain the most reliable results, avoid utilizing rooted devices and emulators.

Q11 How can you test the CPU usage of a mobile device?

For testing CPU consumption, there are several programs accessible on Google Play or the App Store, including CPU Monitor, CPU Stats, Usemon, CPU-Z, etc. These applications are very advanced and archive past data on the processes that are active on your device.

Q12 What is the best way to test a mobile application on different screen sizes?

The most efficient method for testing devices with a wide range of screen sizes is to use emulators.

Q13 How do you perform A/B testing for iOS?

Three procedures may be followed to perform A/B testing for iOS:

Step 1: Create a test that prepares two versions of your iOS application (A&B) with the necessary test metrics.

Step 2: Concurrently test each of the iOS versions on devices.

Step 3: Assessing test findings to determine which version will be the best one to release.

Q14 What are the bugs one usually encounters when testing mobile applications?

Generally speaking, several mobile testers categorize the four categories of problems that are most commonly discovered:

Critical bugs: When testing a specific functionality of the program, the device’s operating system crashes.

Block bugs: Performance issues that may arise while the device is still turned on.

Significant bugs: A particular program feature is unable to work as intended.

Minor bugs: The most frequent scenario falling into a minor bug category is a GUI problem Mobile App Testing Interview Questions.

The process of mobile application testing also uncovers certain other types of defects, such as:

Application performance issues:

  1. An application uses the battery more intensely
  2. Complete lack of responsiveness from an app

Q15 When working on mobile test projects, when should a QA team opt for manual testing versus automation testing?

In recent years, automation testing has significantly improved the efficiency and effectiveness of testers. The first step to optimizing your team’s productivity is realizing when to switch from manual testing to automated testing. Manual testing and automated testing should be done in the Mobile App Testing Interview Questions following cases:

1. Manual Testing

  • When new features are added to the application.
  • When the application needs to be tested just once or twice.

2. Automated Testing

  • When the release cycle requires rigorous regression testing.
  • When complex scenarios are needed to test the application.
