How to test on real devices

This article first appeared in issue 240 of .net magazine – the world's best-selling magazine for web designers and developers.

Quality assurance across a broad variety of real devices is a must to ensure a pleasant user experience, stability and security. If your promise is to deliver mature work on the web, on-device testing has become an inherent part of your workflow.

You can never know for sure if your code performs well across platforms and under different circumstances until you have actually tested it on the real device rather than in simulators, emulators or via remote services. You must test under real circumstances, such as on low-bandwidths, different carriers or in energy-saving mode.

It’s also prudent to test on devices that are not mainstream, such as low end devices and devices running older OS versions because they represent a significant part of the installed base. These will most likely break your work first, so why not start with those? If your project works well on less capable devices, work your path up to the mainstream ones.
