Visual Studio 2012 allows you to better test Windows 8 applications

Microsoft is also opening Windows 8 RTM at the same time as Windows Store, where application developers can start submitting Windows 8 paid apps in stores. As they consider uploading applications, developers should try to test these applications to see if they work well in several different types of Windows 8 hardware. In Nova Bovent, the official Windows 8 Application Developer Blog, Microsoft explains how application developers can use Visual Studios 2012 to test their work. This includes ensuring that the application works well in different screen sizes and resolutions.

Microsoft said in the article:

One of the first tasks of testing is that your application layout will not be trimmed and vertically/horizontally misaligned at any time in the lower resolution screen. On the other hand, you don't want to use a large black area on either side of the high-resolution screen. If your application layout extends beyond the screen, and a user interacts with the keyboard and mouse, the scroll bar should appear in due course.

Visual Studio 2012 also allows developers to ensure that their Windows 8 applications respond well on the touchscreen, and there are several ways you can use code for unit test applications. A later version of Visual Studio 2012 also includes a manual test tool called Microsoft Test Manager, which allows you to test one feature of an application directly on a large number of Windows 8 products.
