This tutorial outlines some of the key mobile application testing challenges. Some key challenges for mobile application testing are as follows:
- Mobile Device Diversity
- Different mobile platforms
- Mobile Network Operators
- Test Scripts
- App store approvals
- Real device testing
- Compatibility Testing
Mobile Device Diversity
The wide variety of devices with different screen sizes, resolutions, hardware capabilities, screen input methods (QWERTY, touch, etc), and operating systems make it difficult to ensure consistent app performance across all devices.
Different Mobile platforms
There are different mobile operating systems and versions in the market. The major platforms are Android, iOS, and Windows Phone. Each operating system behaves differently. Ensuring compatibility across all mobile platforms and versions is a significant challenge.
Mobile Network operators
There are many mobile network operations worldwide, like CDMA, GSM, FOMA, etc. Mobile apps often operate under varying network conditions. Testing needs to account for different network speeds and connectivity issues.
Executing test scripts on mobile devices with varying keystrokes, input methods, and menu structures poses a significant challenge.
App store Approvals
It is essential to comply with the specific requirements of app stores like Google Play Store or Apple App Store to publish an app. The primary requirement is that the app must be available for download from the respective app store.
Real device Testing
The main ways of testing mobile applications are as follows:
- Testing on Emulator
- Testing on a Physical/Real device
Emulators cannot catch all app issues, so testing on real devices is necessary but can be expensive and time-consuming due to market variety.
Testing mobile applications on an ever-growing list of devices and operating systems is a constant challenge. It is necessary to test the compatibility, ensuring that the application works consistently even with different device properties, such as different phones( touch, foldable phones, etc), screen sizes, and resolutions.
It is important to have a comprehensive testing strategy that combines manual and automated testing and the use of emulators and physical devices to ensure thorough test coverage and reduce risks.
