How to disable TestResults folder in Visual Studio?

Solution 1:

I didn't find a way how to disable it completely but at least an acceptable workaround. It moves them to a location that is more appropriate for them. It goes like that:

• Create a .runsettings file in your solution directory (you can give it any name - just keep the extension unchanged) with the following contents which will place the TestResults directory in the %temp% location of your machine. If you're not sure where it is, you can always check it in the command-line by calling echo %test% or just pick any other location.

  <?xml version="1.0" encoding="utf-8"?>
  <RunSettings>
  
    <RunConfiguration>    
      <ResultsDirectory>%temp%\TestResults</ResultsDirectory>    
    </RunConfiguration>
  
  </RunSettings>
  

• You now have to inform your test runner about it.

  • for MSTest users: go to Test > Test Settings > Select Test Settings File
  • for ReSharper users: go to ReSharper > Options > Tools > Unit Testing > Ms Test and pick the Use specific test settings file.

btw, these folders are created always and just won't be deleted if you interrupt the test-runner so it won't clean them up.
