What are some different ways to test a mobile app on different mobile platforms??
What will be an ideal response?
A professional web development department or studio often maintains a large collection of mobile devices for testing mobile apps on various operating systems and with different screen sizes and resolutions. However, because most developers don't have the resources to maintain a collection of mobile devices, other options exist. A number of services are available online that enable developers to interact with virtual versions of many mobile devices. You can locate some of these services by searching on "mobile device testing service." In addition, the makers of mobile operating systems and browsers all provide free programs that simulate interactions with their devices or software.
