The number of mobile app downloads is estimated to exceed 250 billion in 2022. In the present digital era, mobile phones are essential multipurpose gadgets in the day-to-day life of everyone.

What is Mobile Application Testing?

This is the process of running tests against a mobile application to make sure that its functionality and usability meet the requirements and the application is ready for launch. Mobile app testing includes general types of testing as well as mobile-specific ones.

Why is Mobile App Testing Important?

Mobile technology is evolving rapidly and mobile app developers need to deliver the best performing app in a quick time. Getting the best app delivered in the given timeframe requires the automation team to be on their toes. Testers play a critical role in the quality delivery of apps. Moreover, the market is very fragmented which makes testing even more complicated. The mobile app must be tested on different combinations of platforms, networks, operating systems to know how it’s performing.

Writing a good code doesn’t make any sense until and unless your code is passed through a well-defined set of tests. Mobile apps are no longer just mobile apps; they are in the golden era of embracing more progressive & hybrid applications. In such a technologically enabled atmosphere, mobile app testing has become a critical affair.

Mobile application testing is important to meet the following requirements:


  • Ensured functional quality

With testing, we can determine if the app can be successfully downloaded, executed, and interacted with the supporting back-end content infrastructure.

  • Real device testing

This helps to guarantee an in-depth analysis of functionality. Testing the app on live mobile devices always gives a precise outcome for the app and it can ensure that a given feature works on an appropriate gadget.

  • Real-life usage

There are real-time issues such as phone call interruptions, charger effect, and battery consumption that cannot be dealt with by simulators and emulators. Testing on actual devices allows for getting constructive feedback on these questions.

  • Attractive UI/UX

The graphical aspects of a mobile app like the look and feel along with its usability are also tested including the peculiarities of different gadgets. Testing on actual devices helps to assure a user-friendly interface.

  • Loyal customers

The happy and satisfied customers who enjoy using your mobile app will memorize the company as a reliable one and they will recommend your application to friends. With loyal customers and high-quality app features, you can reach thousands and even millions of users.

  • High reputation

Having your applications tested is increasingly considered for any company that wants to stay competitive and get an excellent prestige.

Approaches to Mobile Application Testing

  • Manual Testing

Mobile app testing is a complex process that involves various mechanisms and different skill sets. Manual testing is used by the QA teams to ensure that the final product works as intended. Manual testing is adopted to examine use-cases that may not be all that obvious – expert human testers working in short intervals to swarm the application can deliver exceptional results.

There are tests that can’t be automated simply and they shouldn’t. Some of those tests include:

    • Physical interface tests
    • Complex tests
    • Exploratory testing
  • Automated Testing

There are some cases where manual testing is the better option, as we’ve pointed out before. Yet, some QA tests are either too slow or too complex for human testers. That’s why smartly executed automated testing alongside manual tests, can help assure the release of better products along with the desired quality, faster.

Few automated testing best practices and challenges include:
  • The careful consideration of design, build, and maintenance of accurate test scripts
  • The arrangement and unification of existing engineering workflows with your automated testing process
  • The creation and maintenance of your test automation framework, including infrastructure
  • The management of test runs and setups
  • Meticulous reviews to validate test results and defects
  • Precise monitoring and prompt response to noise and flaky tests

Types of Mobile Application Testing

There are almost 4 million-plus mobile apps available for download, so customers have a huge no of options to choose from. In such a highly-competitive supply and demand scenario, one must ensure that the quality, usability, and security of the mobile app not only meets expectations but exceeds them.

Organization and planning are required on a high scale to ensure you can iterate through the software development life cycle quicker and – ultimately – out to market sooner. Understanding the types of mobile app testing and their functions can help.

    • Functional Testing
    • Usability Testing
    • Performance Testing
    • Fit and Finish Testing
    • Regression Testing
    • Device-Specific Testing
    • User Acceptance Testing
  • Functional Testing:

Functional testing is to ensure the feature works as per the requirements listed in the initial stages. The QA team will have a test plan with a list of actions and the desired app behaviour.

    • The application installs and launches correctly
    • The users can sign-up and login
    • Text boxes and buttons function properly
    • Push notifications render correctly
  • Usability Testing:

This is to ensure the features are user-friendly and they are as intuitive as possible. It is advised to bring in new testers for a “first-use” experience during this step.

    • Good layout and design
    • Intuitive Experience
    • Response time
  • Performance Testing:

The app might work perfectly, but if it takes more time than required to display a simple task, nobody is going to use it. So performance testing is typically more important in later sprints but keeps an eye on the app’s responsiveness as you move along.

  • Fit and Finish Testing:

You can’t lock your designers in a closet just because the design phase is complete. They should evaluate and examine each feature and ensure that their vision was implemented as described in the design. This is an added reason why having one agency for both design and development is so beneficial.

    • Device performance: Start-up time, battery consumption, memory consumption
    • Network performance: Inaccuracies or delays in receiving information
    • Server / API performance: How promptly and in what format data is transferred
  • Regression Testing:

This is to ensure that a code change in the software does not impact the existing functionality of the app. Good QA teams will have a list of tests to perform at the end of each sprint, which will include tests from previous sprints to verify the impact of change.

  • Device-Specific Testing:

There are thousands of device and operating system combinations in the market. At the testing phase, make sure you try out your app on numerous screen sizes and OS versions. Some tools such as Google’s Firebase can help automate this but always test the app on at least a handful of physical devices.

  • User Acceptance Testing:

This is the testing performed by either the app owner or future app users. Always remember who you are developing this app for and keep taking their feedback throughout the process. If a feature clears all the earlier tests but fails this one, what use is it?

What’s the need for Mobile App Testing?

Mobile app testing is essential to optimize mobile apps similarly client-side A/B testing is essential for optimizing web and mobile sites. A/B testing offers a multitude of additional benefits when it comes to mobile apps and these can be leveraged to solve pain points in mobile users’ journeys and significantly improve app-specific metrics.

Below are the reasons that one should be investing in Mobile App Testing to:

  • Optimize In-App Experiences and Boost Core Metrics
  • Fragment Your User Base and Deliver Targeted Experiences
  • Deliver Personalized In-App Experiences
  • Experiment with Features in Production
  • Reduce Risk and Roll Out Features Confidently in Stages
  • Execute and Maintain Continuous Integration & Continuous Delivery (CI/CD)
  • Offer Optimal User Experiences Mapped With User Journeys

What Can You Test in your Mobile App?

  • Messaging
  • Layout
  • UI Copy
  • User Flow
  • Onboarding Flow
  • Subscription Flow
  • Checkout Flow
  • Push Notifications
  • Features & Functionalities

Unit testing is an equally important part of the whole app testing process. The iOS/Android unit testing should happen early in the process of writing code. Doing this leads to better design and helps you and others understand how your code works under different scenarios. There are many other tests depending on the OS as well, like we have Android instrumentation test for Android or Automation test for iOS. Remember – the more tests your app goes through, the closer you are to market success and reaching your business goal.

Testing equates to Quality! Hence mobile app testing is crucial for achieving better app quality and attracting more loyal customers. There is a range of mobile app testing tools to check various features but there are also certain scenarios where manual testing of the mobile app is preferred. The choice should be based on your company’s preferences and capabilities. Testing the performance is an important measure and hence you need to check off every essential step in the mobile app testing checklist before the final release.
