Tests magically disappeared from Test Explorer pane in Visual Studio 2013

Question

I have created a unit test project in VS2013, and I\'m using it to create a test suite for my SQL Server 2012 database.

I have created 4 test classes so far and ever

Answer 1

I just had the exact same thing happen to be. Build, Rebuild, Clean Build, the Test Explorer couldn't list for me my unit tests!

This came after I changed the unit test project's platform target from "any CPU" to x64. I switched it back to "any CPU", built, and they appeared again. How frustrating.
