Terje Sandstrom<\/a> has written two excellent blogs on using Traits in Visual Studio Test Explorer.<\/p>\n

How to manage unit tests in Visual Studio 2012 Update 1 : Part 1\u2013Using Traits in the Unit Test Explorer<\/a><\/p>\n

Part 2\u2013Using Traits with different test frameworks in the Unit Test Explorer<\/a><\/p>\n

In this blog, I will describe how you can implement Traits support for a custom Test adapter. [NOTE: This feature is only available in Visual Studio 2012 Update 1] I will use the XML Test Adapter that I had created in this blog<\/a>. I will add a category attribute for each test case.<\/p>\n

My test xml file looks like this now.<\/p>\n

\"image\"<\/a><\/p>\n

I modified XMLTestDiscoverer.GetTests to retrieve the category attribute from the XML and add it to the Traits property of the test case.<\/p>\n

<p>Now when I open the Test Explorer and the text xml file, I see<\/p>  <p><a href=\"https:\/\/devblogs.microsoft.com\/00\/00\/00\/45\/92\/metablogapi\/2110.image_2F22AE83.png\"><img title=\"image\" style=\"border-top: 0px;border-right: 0px;border-bottom: 0px;padding-top: 0px;padding-left: 0px;border-left: 0px;padding-right: 0px\" border=\"0\" alt=\"image\" src=\"https:\/\/devblogs.microsoft.com\/devops\/wp-content\/uploads\/sites\/6\/2012\/12\/6327.image_thumb_54AC2BE4.png\" width=\"302\" height=\"138\" \/><\/a><\/p>  <p>Super easy.
