title: Visual Studio 2012 Not Recognizing Existing Unit Tests
body: <p>I previously created a Unit Test Project then removed it from my solution temporarily. Now that I have added it back, my unit tests aren't being detected by Visual Studio and I can't figure out how to run them.</p>
  
  <p>I was looking online and I saw that there are some solutions regarding the "Test Tools" settings, but it seems to have been removed in VS 2012.</p>
  
  <p>Has anyone encountered this problem? How can I fix it so I can run my unit tests again?</p>
