Couple of months ago, I wrote an article to the 2nd / September issue of the DNC Magazine on improving the testability of Win8 metro app. It is a pleasure to see that this article has come out nicely in the Magazine.
This article explains how we refactor an existing metro app and improving its testability while using the MVVM (Model View ViewModel) pattern. I also introduce the MoqRT framework and how to overcome challengers of testing metro style apps. This also includes some of the cool features in VS2012 Unit Testing support.
There are some other great articles and including a very interesting interview with Jon Skeet.
