Problem with running test under debugger RRS feed

  • Question

  • I have some unit tests that work fine when I "Run Selection" or equivalent but not when I "Debug Selection". When I do the latter i get an error

    "An exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll and wasn't handled before a managed/native boundary
    Additional information: Could not load file or assembly 'Microsoft.VisualStudio.TestTools.DataCollection.SystemInfo, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified."

    These test run in debug for other developers with machines that should be set up in an identical way. I am running VS 2010 Professional SP1 and Windows 7 Professional SP1. I believe the installations of everything are completely standard.

    Has anyone any insight into why I might get this error or what I might do to fix it. I have tried tinkering with the test settings to no avail.

  • Hi David,

    Thank you for visiting the MSDN forum.

    Did you change the settings in your VS? If you create a new unit test, whether it has the same issue?

    It seems that it couldn't download the .dll file. If you change the platform to “Any CPU”, and debug it, does it have the same issue?

    Try to reset your VS settings, and then debug it with the default setting, check it.

    If no help, would you mind sharing us a simple project? We try to debug it with our computer.

    If there's any concern, please feel free to let me know.

    Best Regards,

  • Hi amine 2,

    Since this case was closed for a long time, if you get any test issue, you could open a new case in this forum, we will follow it in time. Of course, I will unmark the reply.
