Creating a Quality Mobile App Testing Strategy


The mobile verse is depicted through several devices, screen resolutions, operating systems, networks and locations. There are thousands of devices and hundreds of operators across the world, which is why mobile app development and testing are accelerating at a fast rate and assuring great quality has become a top priority.

What can determine a mobile app’s persuasiveness and performance? What drives people to download, purchase and use mobile apps? Companies need to have a concrete mobile app development approach, which will serve as the base for building any app that will thrive under competition. 

Whether it is Android or iOS, any operating system can have hundreds of apps built for it but there is one common feature in mobile app development. It is the ability of the app to make sure that it serves customer expectations and business objectives successfully. This is achieved with the help of a sound mobile app testing strategy. This is an imperative process that every app has to go through before being deployed to app stores.

Challenges in Mobile App Testing

Like any desktop or web application, testing of mobile apps brings forth the quality and performance of the final product. However, it can be a daunting task because of the following reasons:

#1 Multiple Devices

Mobile apps are used on several devices. Whether Android or iOS, there is large amount of fragmentation in the device market because of which testing becomes a challenge. Different operating systems and different versions of the app and testing it works on which platform most suitably can be quite a headache. Testers need to ensure that the app is compatible on all devices, platforms and operating systems.

#2 Outsourced or In-House Testing team

Project deadlines and tight budgets make it difficult for decision makers to finalize the mode of testing the mobile app. An in-house team will work or outsourced support is needed. Outsourcing this function can get you qualified talent but you need a partner that is credible enough!

Alternatively, an in-house team might give you a better picture of your app’s compatibility and future in the app world. 

Irrespective of the options that you have or you choose to pick, hiring a qualified and experienced team for testing your mobile app is necessary. 

#3 Mobile App Testing Tools

Whenever a business deploys in-house team for mobile app testing, it might lack testing tools and efficient methods that are a prerequisite. Multi-device compliance of the mobile app requires sophisticated testing and following of certain guidelines and industry standards. This is the reason why many companies choose to bring in a testing partner and separate tools for mobile app testing.

How to Create a successful Mobile App Testing Strategy 

Certain factors can help you in developing a mobile app testing strategy that gives you the best results.

#1 Selecting Device

The most important concern in testing the mobile app is the choice of device. While selecting the device as well, you need to ascertain the model or choose an emulating device. Consider the following:

  • Testing your app on stable operating systems
  • Use different screen resolutions and size
  • Test if the app is compatible with smartphones and tablet devices

While selecting the device, memory and connectivity options need to be considered.

#2 Choosing Emulators or Physical Devices

One can choose between emulators and physical devices too. Primarily, device emulators can be useful since they assist in quick and efficient testing in an agile environment.

They are cost efficient too as they work perfectly for basic app functionality testing and feature development. 

Testing on physical devices is quite necessary as it allows understanding the application in real time. It is good for beta testing phase that gives you wider geographic coverage. It allows you test your app for factors like:

  • Multiple networks
  • App behavior on certain devices
  • Interaction with the real world
  • Diverse devices

#3 Network Testing

Majority of mobile apps depend on network to work perfectly; hence, it is important to test the mobile apps in actual network environment to get the real picture.

There are certain network simulation tools available that can test the mobile apps for network speed, bandwidth, dropouts etc. They add value to testing processes and provide consistency to app’s testing and performance across various networks.

#4 Manual Testing vs. Automated Testing

Automated testing or manual testing, which one should you go for? 

Automated testing requires significant investment. Conduct automated testing if:

  • Your app is growing 
  • Mobile app development lifecycle is long 
  • Regression testing scale and frequency is high

With automation, mobile application testing becomes simpler:

  • Helps in verifying app’s compatibility with new operating systems
  • Validate app’s backward compatibility during upgrades

Manual testing is also important for conditions that cannot be tested with emulators. Both automated and manual testing is required for mobile apps to work successfully.

#5 Performance Testing

It is always a good idea to test the performance and scalability of your app. Smartphone users have large amount of data stored on their devices like text messages, audio-video clips, album photographs etc. With time, this data grows into enormous proportions and hence the testing must involve different scenarios to see how the app performs.

#6 Security Testing

Security of the app is of utmost concern; it is not optional but imperative. Users can have personal data, even financial information that is confidential. If the app is vulnerable to security threats, it might spell doom for its own future. Check the following:

  • Does the app contain credit card information or other similar details?
  • Does the app use secure networks and can it be switched to insecure ones?
  • Does your app ask for permission from user?
  • Does your app require authentication?
  • Is there any system of maximum login attempts before the app gets locked?


Mobile app testing is becoming more complex as mobile devices become more sophisticated and the market gets bigger. Companies need to think forward and use tools to simplify the testing process. Plan the selection of devices and other factors to proceed towards a successful release.
