Recently while working on a project I encountered an issue with MTM not able to associate with automation.
Association of test case to automation is well explained in this article : http://msdn.microsoft.com/en-us/library/dd380741.aspx
I couldn't associate automation because :
1) I didnt see ellipses (...) at all in MTM ( under 'Associated Automation' tab ).
~ So I moved to Visual studio and ran my query to open test cases. I could see ellipse button under 'Associated Automation'.
2) On click it just brings a blank modal window. I do not see any tests in "Choose Test" window".
~ I have a solution opened from TFS.
~ I was able to successfully build them and have the dlls created.
~ But, when I clicked the ellipses (...) in the Associate Automation, I don't see any tests.
Well reason for such behaviour is : Project that I created was NOT test Project type. I created a class library project while i was re-factoring my code.
Simple fix for this problem is make this project as test type or manually modify <ProjectTypeGuids></ProjectTypeGuids> to
