Mobile App Testing

Mobile Application Testing refers to the process of validating a mobile app (Android or iOS) for its functionality and usability before it is formally published.

 Mobile app testing enables QAs to confirm whether an application satisfies the expected business and technical criteria.

Teams must test apps across a range of screen resolutions, operating system iterations, and network bandwidths in order to conduct successful mobile application testing. When the app is made available to the general public, this helps to assure flawless performance across a variety of device setups.


At a high level, testing mobile applications includes the following:


  • comparing the performance of programs on various OS versions (for example Android 7.0, 8.0, etc)
  • examining how an application would look in landscape and portrait modes
  • Verifying an app’s performance and compatibility when used with a particular configuration
  • Testing the app’s compatibility with mobile sensors such the GPS, accelerometer, and gyroscope.
  • Checking the functionality of the app’s GUI (Menus, dropdowns, navigation buttons, etc.)


Why Is Mobile Application Testing Critical?

If mobile applications are not thoroughly tested, there is a great likelihood that users could run into serious issues on their device, that may lead to a bad user experience, especially for new users.

 Keep in mind that each mobile app’s success depends largely on its first impression.

The ultimate goal of developing mobile apps is to increase business outreach to more users across the globe. However, if the software is broken or challenging to use, people are unlikely to use it. Naturally, no company wants their clients to uninstall their apps and use a rival.

Here are some important figures that demonstrate the importance of mobile application testing:


  • 80% of users delete or uninstall an app that doesn’t meet their expectations
  • If an app is too slow, 48% of customers remove it or stop using it.
  • 50% of users tend to remove apps that take up too much space from their devices.

 Two Biggest Software Failures In History


1. Supper Buggy Spacecraft Launch

Although there are various sorts of software problems, Boeing’s clumsy software errors are difficult to overlook. Boeing’s disastrous software not only killed 346 people but also destroyed the 737 max aircraft.

It’s CST-100 Starlinerspaceship was a success, NASA decided to look into the company’s software because of several technical code problems.


2. Software Fault Was a Cause of Airbus a400M Plane Crash

In May 2015, Airbus got scared when he reported a software bug in its A400M aircraft. The company immediately took action to fix the issue, which was a fatal crash that happened in Spain.

Four members of the air force were killed in this incident, and two people had already been hurt during a test flight in Seville before this operation. These cases are examples of why technology testing has an important role today.


How Does App Testing Benefit Your Business?

End users in the real world can download and utilize the app on any of the more than 9000 different mobile devices. It goes without saying that the program must be sufficiently customized for that specific device in order to function properly.

Mobile device usage has surged as a result of smartphones’ ongoing growth. Global mobile user numbers are anticipated to reach 7.5 billion by 2026. When compared to the 3.6 billion smartphone users in 2016, that is a twofold increase.

The statistics unmistakably show that the use of mobile devices will increase significantly in the near future. The popularity of mobile devices will also encourage the creation of cutting-edge mobile applications that will increase access to corporate services. Businesses will obviously need to make sure that their mobile apps are prepared for modern devices and optimized for them. Only through testing and optimizing programs on the most recent mobile devices will this be possible.


Who Performs Mobile Application Testing?

Anyone who wants to release a successful, optimized mobile app performs mobile application testing. Mobile application testing is often carried out by a dedicated team of QAs for each sprint by app development teams. Testing of mobile apps frequently includes non-QA stakeholders, such as developers, managers, product owners, and future consumers.

In fact, since it considers diverse viewpoints, mass involvement in mobile app assessments is highly advantageous. Product managers will be in a better position to provide non-technical insights than QA managers. Having people from various jobs weigh in on the app’s functioning will help it become a more well-rounded product likely to appeal to more customers because a good app needs to be much more than just technically effective.


How Do I Select the Right Devices for Mobile Application Testing?

Simply said, research. Analyze your app’s target market before you do anything else. Learn as much as you can about the consumers’ general preferences, preferred devices, operating systems, and geographic locations. As a result, QAs will be able to optimize their processes and better cater the app to the requirements and expectations of customers.

Business and marketing departments typically make the choice of which devices to test on (or the client). Goals defined by these teams help focus the product/testing team’s efforts in areas that will be most rewarding with the least effort.
