In this blog post, Rui Sun and Andre Hamilton explore some Visual Studio 2012 capabilities that will make it easier to test and verify Windows 8 applications. Visual Studio 2012 has a simulator that reduces your need to have physical devices of every form factor at your disposal for testing. You can launch your application in the simulator directly from within the Visual Studio through the debugging action. Then you can interact with your application using the mouse or using simulated touch on your development computer with gestures like swipe, pinch to zoom and rotation. Visual Studio also provides a unit test library project for Windows 8 applications written in C#, VB.net or C++.
