An Overview of mobile application testing

Mobile testing or mobile application testing is a process performed to test the functionality, consistency and usability of an application software specially developed for different handheld devices and to support their operating systems, such as iOS, Android, Blackberry, Windows, etc. A thorough mobile testing process ensures that an application must best suit all the characteristics of a mobile device such as hardware & software capability, physical dimension, connectivity capability, etc.

Overviewing these mobile testing interview questions and answers for experienced as well as individuals and the other crucial factors mentioned here can be extremely result oriented for candidates and new learners to this niche.

For mobile application testing, these are the few primary testing procedures mostly performed:

  • Functional Testing
  • Performance Testing
  • Memory Leakage Testing
  • Installation Testing
  • Security Testing
  • Black Box Testing
  • Load Testing
  • Usability Testing

For those who are looking for Android Mobile Testing Interview Questions, we have also included some of the questions for them. Go through it.

The mobile app testers either use a real device or an Emulator/Simulator for the application testing process. Both have their unique benefits, such as using a real device for mobile testing can benefit with faster processing and most accurate results, whereas using an Emulator/Simulator can be cost-effective, less latency, user-friendly, but also gets low-reliability score due to its deniability to stimulate all types of user interactions. Mobile application testing can be performed with both automation and manual modes.

To get into complete detail of mobile testing, we are mentioning some of the important Mobile Testing Interview Questions. Go through the questions as they will help to you.

Advantages of Using Mobile Testing

We, testers work to find four types of common bugs; critical, block, minor and major. To example there, a phone system crash when testing a particular feature of the device will be classified as a critical bug. The GUI bugs will be categorized as minor bugs, and functional disability of a particular feature will be submitted to a major bug list. Certain performance unavailability through the device is ON will fall into the block bug list.
