title: Can you set Temporary Environment Variables for MSTest Run Configurations?
body: <p>I am using MSTest in Visual Studio 2008 with C#. I have a specific environment variable I would I would like to and a path modification I would like to do only during the run of either specific tests or better yet all test within a run configuration.</p>
  
  <p>I tried using the test run configuration Setup script to do this but as I expected since it is a batch file the changes are lost once it exits, so that wont work.  </p>
  
  <p>Is there any other way to setup temporary system environment variables that will be valid during all tests being run?</p>
