But how can you test your system during development and avoid the pain of managing and switching between multiple devices?įortunately, all modern browsers offer mobile emulation tools, and one of the best can be found in Chrome. Features such as mouse hover won’t necessarily work and your application could be inoperable. If you’re coding on a regular PC with a mouse and keyboard, it’s difficult to appreciate how your masterpiece will operate. The process is complicated further by touch-screens, hybrid devices, and high-density displays. In extreme cases, it could take as long as the original development. Your latest masterpiece must be rigorously evaluated on a range of mobile, tablet and desktop devices with differing OSs, screen resolutions, and capabilities.
