The word ‘app’ was originally coined by techies as shorthand for ‘applications’, but since mobile devices came into their own, this tiny word is in everyone’s mouth and even found its place in Oxford dictionary. Yes, we are almost on the verge of being ruled by ‘apps’ on our devices. From shopping, education, travel, chat, games, fun, entertainment, there are apps for almost anything and everything.
With this overwhelming volume of mobile apps, maintaining a high technical standard and offering the best user experience is the key to success for the app developers. Naturally, mobile application testing has become more important than ever. The changing spectrum of mobile devices and the continually evolving operating systems make testing more and more challenging. Here I introduce the biggest challenges in testing mobile apps.
1. Variety of Device
The expanding horizon of mobile devices, with their ever increasing and increasingly varied features, is the most formidable challenge of all. Each different device comes with a different set of metrics, including the following:
- Different screen sizes and dimensions.
- Varying pixel density and image resolution.
- Varying input methods, for instance touch screen, Querty keypad, etc.
- Varying feature set and user interfaces.
Obviously, a developer cannot test his app on this entire plethora of devices, but, in most cases, will restrict his tests to the most common and popular devices. Mixing in different OS and OS versions adds more dimensions to this maze of complexity. Using emulated devices is a semi-solution to address this problem, but then the app will not be tested in a real device environment so the possibilities of technical glitches will always be there.
