title: AppDomain.CurrentDomain.BaseDirectory changes after running test?
body: <p>In VS2012, I have a bunch of (MS) unit tests, which use different xml/text files I've stored in the same folder as the test file class.</p>
  
  <p>I open these files using File.OpenRead(AppDomain.CurrentDomain.BaseDirectory + "file")</p>
  
  <p>If I run just one test, it works, the file is read.</p>
  
  <p>If I run all the tests at once, the BaseDirectory returns a different path (in TestResults/Deploy/currentdatetime/Out) and obviously cannot find the file there.</p>
  
  <p>What to do?</p>
  
  <p>Thanks! </p>
