title: TFS 2013 after build does not run the unit tests, no errors
body: <p>I am working on a web app, solution in VS2013 with several project in it, one of them is used for unit tests - Ms Unit test framework.  We have TFS 2013 set up to build the solution after each check in and trying to run the unit tests after each build.</p>
  
  <p>From some reason unit tests are not executed after build, but also there is no error indicating that something broken or not found. I tried lot of things regarding editing the build definition - change the 'Test assembly file specification' to ***test*.dll, to use the exact dll name, changed the Target platform ...etc.</p>
  
  <p>If I look into the log file I can see this:</p>
  
  <blockquote>
    <p>Run VS Test Runner 00:00:15 Inputs TestSpecs: BuildParameter[] Array
    Enabled: True ConfigurationsToTest: OutDir: The RunTestsActivity was
    invoked without a value for Platform or Flavor. The values Any CPU and
    Debug were used.</p>
    
    <p>Test Run Completed. 0 tests executed.</p>

  <p>What should I take a look, or what could be the problem ?</p>
