Hybrid, Native, and PWAs: Testing your mobile apps for compatibility

Fragmentation testing is crucial for mobile applications due to differences in device features, APIs, and operating systems. Hybrid apps are the most affected by fragmentation as they rely on native-OS browsers (WebViews) which can vary across devices. Native apps also face issues with different OS versions, while progressive web apps depend on browser-OS-hardware interactions. To prepare for fragmentation, developers should test their apps on various mobile screen sizes, network conditions, and Android/iOS versions. Additionally, hybrid app functionalities should be tested on both mobile OS and browser versions, native apps should be tested on real devices for battery overconsumption and hardware performance issues, and PWA functionalities should be tested on different OS-browser combinations.
