Focus Areas for Mobile Application Testing

Why is mobile application testing so important?

Smartphones are undoubtedly becoming a vital organ for people, without which tasks look impossible to accomplish. The wide gamut of mobile applications has simplified life to such an extent that everything can be done at the tap of a button.

However, developers need to understand that developing mobile applications is challenging, thanks to the variations in devices, operating systems, network, and user skills. Moreover, the scope of an app tester's functions has also increased to ensure an app’s high performance under differing usage conditions. But the question remains the same: how can testers ensure the functionality and performance of apps?

Key aspects to remember while testing mobile applications

Accurate and complete testing should be included in application development strategy. In order to ensure the efficiency of the testing process, app testers should focus on following key areas:


Today's digital world is dominated by iOS and Android smartphones, which are known for their wide application platform. But selecting a device has always been a challenge before testers because of the dynamic nature of smartphone technologies. The choice of devices corresponds to the market and reach for the mobile application. Testers can consider the following factors while selecting a testing device:

  • OS Version: Use stable operating systems to test mobile applications
  • Screen Resolution: Use a combination of screens to test by resolution and size
  • Form Factor: Test for form factors if the app is compatible with tablets and smartphones

Moreover, connectivity options and memory size are also important factors that testers should consider while selecting devices.

Emulators and physical devices

Emulators are extremely useful during the initial stages of app development because they allow efficient and quick checking of the application. Emulators run software from one environment on another environment without intrinsically changing the software. Device emulators are cost-effective testing options and create a pseudo-live environment for testing applications. But it is also imperative for testers to test applications on physical devices for ensuring an app's functionality in real-life scenarios.


The performance and scalability of applications are important areas that testers should focus on. Since users have a large amount of data on their smartphone, testers must ensure that their app continues to perform on heavy-data smartphones. Testers should test the app in scenarios where there is an increase in the size of albums, mailboxes, messages or any other type of content. Moreover, testers should test the server side of the app with many users for ensuring the app’s performance.


Cloud-based app testing is essential in the present-day realm of cloud computing. Cloud-based app testing makes it easier for testers to manage potentially infinite scenarios. It provides a web-based testing environment where applications can be positioned, tested and managed effectively. Testers should focus on cloud-based testing because reducing defects is linked with unstable test configurations. Moreover, it reduces time to market (TTM) and augments the testing process.

Network compatibility

Since most mobile applications rely on power networks to work accurately, testers need to ensure that their app performs on an actual network. Testers can use a range of network simulation tools to test mobile apps against network speed, connection dropouts, bandwidth limitations and other network-related aspects. Network simulation adds value to the testing process and ensures that the app delivers performance under varying network conditions.


Last but not the least, testers should focus on data privacy and security testing. Testing an app’s security is a compulsory component of the testing strategy because users are concerned about the security of their credentials and data. Mobile applications should encrypt credentials of users while authenticating them over a network. Testers should identify loopholes and vulnerabilities in the app which would jeopardize sensitive and confidential information of users.
