Mobile market growth is increasing day by day. The mobile industry has been skyrocketing for several years, as consumers spend more time on multiple devices and mostly utilize mobile content.
The hardware has improved dramatically over the last few years, but it’s the software that truly unleashes the potential of devices. What’s really driving is the incredible success of smartphones and tablets in the application market.
Mobile application testing is different and more complex than testing traditional desktop and web applications and has its own set of new challenges.
The main challenges shall be introduced in the following ways:
1. Increasing Fragmentation of Mobile Devices: It marks a major problem for mobile application developers and testers. Android devices differ in their shapes and sizes with vastly different performance levels, screen sizes and input methods.
With different hardware capabilities a tester cannot guarantee that a software application will work fine on all the devices after testing on one because the screen resolution, CPU, Memory, OS optimization and hardware could be different.
Solution: When you need to maintain a variety of phones and tablets in all models and operating systems for 24/7 access, a private mobile device cloud such as Mobile Labs’ device connection can help you to manage your mobile testing lab’s assets more efficiently.
Since testers can access devices from disparate locations, device sharing is more practical.
2. Different OS Version: There are many different OS versions with their own limitations available in the market, but also a variety of versions of the same OS. Both iOS and Android average 1-2 major OS releases per year (e.g. Android Marshmallow 6.0, iOS 9.0), and 1-2 major point releases during that period (e.g. Android Marshmallow 6.0.1, iOS 9.2).
While all releases claim to be backward compatible, sometimes applications, unfortunately, end up with unexpected behaviour (i.e. bugs) when deployed on a new OS.
Solution: If an application is working fine on the latest two OS versions with the latest top-selling devices, then we ensure the application is working fine.
3. Mobile Network Operator: Another challenge in mobile application testing is represented by the huge number of Mobile Network Operators.
At the moment there are more than 400 Mobile Network Operators in the world, that use different network standards and different kinds of network infrastructure.
Solution: The solution to this challenge is to use device emulators plus an operator’s web or test proxy, which avoids airtime charges and lets testing proceed with an instrumented test stack.
Short of acquiring in-house accounts with target networks, cloud-based network test services provide the most realistic testing scenario. Many cloud-based device testing services include remote carrier coverage.

4. World Wide Use: The international use of applications marks an important challenge in Mobile Device Testing.
As many apps are developed for international markets – apart from that the mere translation of contents –regional traits, time zones and target audiences must be taken into account.
Also, the Arabic script or other right-to-left languages can be a serious problem for developers and testers.
Solution: While testing the mobile app, you need to ensure that it supports multiple languages and currencies without any hassle. Also, you can consider allowing users to access information and popular social networks in their native languages through the app.
It is necessary for the design phase to include all possible cultural differences to implement navigational structures and general design principles to satisfy clients on a global scale.
