Some of the common challenges with Mobile App Testing

mobile app testing challenges

Testing different screen sizes:

The screen sizes of mobile devices vary greatly, such as for an iPhone differs from android and some other smartphones. Mobile apps need end-to-end testing to ensure that the apps work seamlessly on different screens. Testers have to check different layouts and elements against different pixel densities, which is a time-consuming process.

Varying battery consumption:

Mobile apps tend to consume battery life quickly. Users often use multiple apps at a time on their mobile phones. Hence, the apps that are left open in the background drain the battery power. Mobile app testers should ensure that the apps do not take much battery power even if used for extended hours or with multiple apps in the background. Testing the battery consumption for various devices under varying conditions is a tedious task but is an essential aspect of mobile apps.

Frequently changing user requirements:

Mobile apps and features are often upgraded as per the user requirements. With these frequent changes, each time, the newly detected bugs should be fixed to ensure flawless apps.

OS version fragmentation:

There are numerous versions of the operating systems available in the market. These OS versions get upgraded from time to time. OS version fragmentation is a big issue for android devices as these devices have more OS versions when compared to Apple’s iPhone. Testers have to test each combination of OS version and device to ensure that the app performs seamlessly across all OS versions.

How to overcome Mobile App Testing challenges?
