Are you trying to show additional traits of tests in the Test Explorer? If so, you can use the "Group by Traits" supported added in the Visual Studio 2012 Update 1 (ref detail at http://blogs.msdn.com/b/somasegar/archive/2012/11/26/visual-studio-2012-update-1-now-available.aspx, download from http://www.microsoft.com/en-us/download/details.aspx?id=35774).
In short, you can decorate your test with something like
public void TestMethod1()
Once this test is discovered again, choose "Group By Traits" (toolbar in the TextExplorer tool window) shall group tests based on your traits (e.g. SpecialTestType, XXX).
