A guide to mobile application testing

Mobile technology has been evolving at an unprecedented rate in recent times. There is a range of mobile applications that provide customers with a range of options. Therefore, business organisations must focus on different mobile application testing types.

What is mobile application testing?

Mobile application testing is a process used to test applications developed for mobile devices. The main intention is to test the applications for functionality, stability, and usability.

Mobile application testing is essential for an application’s survival in the market. The application is also tested for different aspects such as its performance, security, and UI to provide the best possible quality for the end-users.

Why is mobile Testing necessary for applications?

In today’s mobile-application development scenario, applications need to be tested across a range of mobile devices and operating systems to test their compatibility, usability, and consistency. Automation testing can be used to build applications that are scalable and accessible across multiple platforms.

Since manual testing is costly, time-consuming, and vulnerable to errors, it is better to leverage automation for various repetitive tasks, including regression and performance testing. Automated testing will let the testers quickly check the application’s new or recent updates or modifications for defects, errors, and vulnerabilities. In addition, it helps them to:

  1. Parallelly run tests on different devices
  2. Reuse tests
  3. Obtain improved coverage
  4. Get a better return on investment

What are the different types of mobile application testing?

  1. Usability Testing – it is optimal for determining how the application makes it easier for users to achieve their objectives. For this test, participants are assigned specific, realistic scenarios of using the application. Usability testing is reliable since the feedback is directly collected from the end-user.
  2. Performance Testing is an essential mobile app testing variant. It reviews an application’s stability, speed, and responsiveness under various workload conditions. A performance test’s primary intention is to ensure that an application perfectly aligns with the performance aims.
  3. Functional Testing – it examines if the functions of an application are working correctly or not. Functional testing concentrates on the app’s functioning according to clients’ needs.
  4. Security Testing – security is one of the significant concerns of every mobile application owner. According to reports, eighty per cent of users are more likely to uninstall an application because of security issues. Therefore, it is necessary to focus on security testing for mobile applications.
  5. Interruption Testing – it is effective in testing the behaviour of an application in an interrupted state before resuming the previous state. The interruptions can take different forms, including low or full battery, alarms, incoming calls or messages, push notifications, and others. A tester should consider the UI issues, app crashes, and performance issues when they are performing interrupt testing.
  6. Compatibility Testing – it examines the compatibility of a mobile application with various operating systems and their respective versions.

Compatibility testing is non-functional testing essential for ensuring a mobile application’s operation on various operating systems, devices, applications, specific internal hardware specifications, and network environments.

  1. Installation Testing: it examines if an application is correctly installed and uninstalling. Installation testing also ensures that application updates are smoothly working.
  2. Localisation Testing is an essential requirement for mobile applications that aim at a particular geographic reason. Localisation testing is necessary to check the mobile application’s responsiveness to a specific region’s language and culture-related aspects.
  3. Automated Testing: it is used for regression testing or when situations demand repetitive tasks. Automated Testing helps in assuring application quality and quick releases.


The mobile application market is very competitive. Therefore, there is a demand for better usability, security, and quality of mobile applications. Mobile application testing helps identify a mobile application solution’s flaws and improves it for the target audience. Business organisations must focus on the different types of mobile testing to discover various perspectives for assessing an application’s potential performance.
