What is mobile apps  testing? Why do we need to test our mobile apps before deploying them in app stores?

Mobile technology is undoubtedly a disruptive technological invention and has become an integral part of human life. As per a recent survey, people in the USA are spending more than 90% of the mobile time on the apps.

In July 2009, only 65000 apps were on the app store. Now with the new businesses entering the digital world, there has been an increase in the number of apps in the app-store to 3.5 Billion!

In fact, Enterprises of all sizes are using mobile applications technology to fuel up their operations and to satisfy their customers. This will let customers get access to a plethora of apps to choose from.

But will the customer install your application of all the alternatives that are available in the app store?

Will they be able to use it easily? How can we ensure that the app is of best quality? How can you increase the number of downloads of your mobile app?

This shows us that there is a need to deliver the best quality mobile app. 


According to Wikipedia, “Mobile application testing is a process by which application software developed for handheld mobile devices is tested for its functionality, usability and consistency.”

Today we are living in a digital world, and all the generations have clanged to the mobile revolution.

People used to switch ON their laptops or desktops for everything they need to work on. Now, they are choosing mobile devices, as they are convenient and provide quick solutions. Hence we should test the mobile applications before we hand them over to customers to use.

Basic characteristics of a highly efficient mobile app:

From the conception of the idea of a mobile app to planning and writing code, there are a lot of elements that will affect the efficiency of a mobile app. So, here we are, giving some insights into what makes a mobile app highly efficient. 

Basic characteristics of a highly efficient mobile app
    • Uniqueness and Simplicity in design
    • Great UI
    • Fast loading time and performance
    • Compatibility across various mobile platforms
    • Payment gateways and securing data associated with it. Etc.,

Types of Mobile Apps:

There are 3 basic types of mobile applications, namely, Native apps, Web apps and hybrid apps.

Native apps:

Developers develop the Native apps exclusively for a single mobile OS. For example, apps built for iOS will work only on iOS devices. Similarly, apps developed for Android, Windows phone, Symbian or Blackberry respectively, cannot be used on other platforms. 

Web Apps:

These are server-based apps, which will allow a user to access websites on their mobile devices using internet browsers and connections. Usually, developers develop web apps either in HTML or JavaScript or CSS.

Hybrid Apps:

Hybrid apps are known for their cross-platform compatibility. As their name suggests, these apps are a hybrid, having the pros and cons of both native and web applications. These apps are easy to develop but lack in performance and speed compared to native and web apps.

Why do we need mobile apps testing?

QA has become an integral part of almost all digital products. In case of mobile app development, QA is more critical. Overlooking mobile apps testing and QA, in the development process will result in breaks, bugs, errors and in worst-case scenario, a bad customer experience.

Delivering a high-quality mobile app in a given time frame is possible only through continuous & rigorous testing. As the market is very fragmented, Mobile application testing became very intricate. Quality is the key to app success. 

Ensuring the quality can be possible only when we perform mobile app testing on multiple devices, networks, operating systems and in different environments.

Therefore, performing comprehensive testing on a Mobile app helps us in delivering high quality app, as the process involves testing functionality, usability and consistency.

How a mobile app differs from a desktop app?

Usually, we do testing in case of desktop apps on the CPU whereas in case of mobile apps, we test apps on handsets like Samsung, iPhone, Blackberry etc.,

Desktops use broadband connections or Wi-Fi. But mobiles use 3G / 4G or Wi-Fi connections which makes the mobile apps testing more challenging. Also, the mobile apps should be compact in size as the mobile devices will have less memory and screen-size compared to the desktop.

desktop app vs mobile app

The automation testing tools which we use to test desktop apps might not work for the mobile apps. Availability of different operating systems, screen sizes, models and hardware configurations like touch screens, are making the testing process even more complicated.

So, the testing process should be in such a way it results in the creation of highly efficient, and best in the quality mobile app and thereby you can increase no of downloads, app ratings and customer satisfaction.

Types of Mobile app testing:

  1. Usability testing
  2. Compatibility testing
  3. User Interface testing
  4. Security testing
  5. Operational testing
  6. Localization testing
  7. Performance testing
  8. Installation testing
  9. Functionality testing
  10.  Recovery testing
