Tanuj Vohra (Partner Director of Program Management, Visual Studio Test Business) has recently published a nice article on Trends in Software Testing on ITMagz.com. It is summarizing the current trends and techniques of software testing. Test Labs Virtualization is of course one of the items there, as well as other solutions that are part of VSTS 2010, and some other trends that VSTS is not addressing.
Hope you will find it an interesting read.
