What Is Mobile App Testing and Why Is it Important?


It’s no surprise that mobile app downloads surpassed 230 billion in 2021. Today, thousands of apps are available for every mobile device and any function imaginable. Companies are racing to create the next best app for their customers.

However, when creating the next best app, companies face performance issues, a bad user interface, crashing, or compatibility. To overcome these issues, the best strategy is to invest in tools to test mobile apps

What is Mobile App Testing?

Mobile app testing is the practice of verifying a mobile app for usability and functioning before the app is released to the general public, and also ensures that the app fulfills all required business and technical requirements.

When the app is deployed publicly, testing ensures that it works appropriately across various device setups. Mobile apps testing entails the following tasks at a high level: 

  • Performance testing of programs on various OS versions (Android, IOS)
  • Examining the appearance of apps in landscape and portrait modes, 
  • Validating the performance and compatibility of programs when used under specific situations 
  • Testing the app’s compatibility with mobile sensors such as the gyroscope, accelerometer, and GPS 
  • Testing the app’s user interface (menus, dropdowns, navigation buttons, and others)

Why Is Mobile App Testing important?

Today’s mobile app users have numerous choices and a low tolerance for performance difficulties. If you don’t provide a fantastic app experience, customers you just got after spending a lot of money on marketing will uninstall your app and give you a bad review in the same breath. 

QA testers do several tests while the product is in development to ensure that such performance concerns do not arise when it is released. Here are more reasons why testing is essential. 

Improve App UI/UX

With better app testing, businesses can check the consumer’s behavior and evaluate the complete app experience. You can investigate the rationale behind the app and verify that it is simple and easy to use.

Improve Performance 

The goal of testing is to ensure that the mobile app works flawlessly. You can test whether an application meets required performance specifics such as varying load circumstances, changing networks, and devices. 

Testers must select whether they will test with real devices or using emulators. Simulators are helpful in the early phases of the development process, but real devices should be considered before releasing your app to guarantee that it runs well.

Check Use in Real World

Phone call interruptions, charger effects, and battery usage are challenges that simulators and emulators cannot handle. Testing on real devices allows you to gain helpful feedback on these issues. 

Increase App Users

Customers who love using your app will remember your company as trustworthy and tell their friends about it. You can reach hundreds, if not millions, of people with a devoted customer base and a high-quality app. App testing ensures you provide an excellent app. 


You must be able to create a high-quality, user-friendly app to stand out in a market flooded with mobile apps. Testing mobile apps may appear to be a challenging undertaking, but if you do your research and incorporate a testing plan into the development process, you can create a highly-rated app that will rocket to the top of the app store rankings.
