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

I was making use of a public TestContext TestContext method to write to the test output and changed the scope to private. This made every test not discoverable. Changing it back to public helped.
