testmethod Code Snippet

This is an installment in my Zero-Friction TDD series. If you are a regular reader of this blog, you may have noticed a certain pattern in my unit test examples (like this one ). This is because I always follow the Four-Phase Test pattern (which is a

Anonymous Variables

Zero-Friction TDD

cleantestresults XML Snippet

About a year ago, I wrote about an automated way to clean up the TestResults folder created by VSTS. While I still use this approach methodically, I've begun to find it tedious to find my original post to copy and paste the XML into the project file.
