And ignoring or underestimating this stage can lead to two outcomes. First, you will lose potential customers; second, your brand reputation will suffer. Let’s dive deeper to understand how mobile application testing affects your business and users. 

An Overview of Mobile App Testing 

Mobile app testing is a process for checking mobile apps on any OS to check functionality and usability before marketing. Testing these mobile apps help you understand the flaws and verify the technical and business requirements. And you need to check its compatibility across OS versions, screen resolutions, and network bandwidth. So, it ensures the flawless functioning of the mobile app when publicly released. Additionally, many tech giants are there to offer the application by investing in the loads and high ROI. And you could also use proficient mobile testers for your application testing cycle. On a broader level, testing involves: 

  • The app works flawlessly across multiple versions. 
  • Appearance in the portrait and landscape modes. 
  • Validating compatibility and performance of application. 
  • Consistent with mobile sensors, such as GPS and gyroscope. 
  • Checking the app’s graphical user interface for functionality 

Why is mobile app testing critical?

It is just a simple question if you lock your car door and test it, it shouldn’t get unlocked with any door key or house key! The same scenario applies to mobile apps and feature testing. Mobile app testing increases with the complexity and cost of mobile apps. In the long run, the extra work involved in quality assurance pays off. Firstly, it provides double-verification of your mobile apps. Second, it broadens your business reach across the globe.  

You may have heard the first impression is the last impression it is apt for your mobile app business too. Faulty apps cause problems for users and cause them to abandon them. If the mobile app isn’t tested enough, it can cause unwanted abruptions frustrating for new users. Half of your potential customers can go away from unwanted crashes and bottlenecks. And this loss is reflected in their poor reviews, inadequate performance, app crashes, and battery drain.  

Mobile app testing vs. Web app testing 

Mobile applications are designed for mobile devices, whereas web apps are for web servers and browsers. The development of web and mobile apps differs. Furthermore, how users interact with these apps through gestures such as scrolling and zooming on their touchscreen sensors. Their testing methods differ from their names. Mobile app testing is testing an app across multiple mobile devices. And web app testing is concerned with validating the appearance and functionality of websites across numerous browsers.
