MSTest: No tests are run because no tests are loaded or the selected tests are disabled

Question

I have a c# solution with the following structure:

mySolution
  myProject
  myProject.MSTests
    References
      Microsoft.VisualStudio.QualityTools.UnitTe         


        

Answer 1

This must be a bug and is an absolute pain especially as you have to reenable every single test method individually. However a bit iof lateral thinking produced a better solution - rename the test class and rebuild. Then rename it back. Seems to work. Ooops - no it doesn't. Renaming the class works but when it's renamed back it reverts to the original settings. The trick is to close down Visual Studio and delete the .vsmdi (visual studio test meta data) file. This will be regenrated.
