After installing the Test Studio trial edition, tests created using the WebAii framework (free version) no longer run on the same box that Test Studio is installed. Our trial ended with a purchase of the commercial license, but we'll need to continue running tests on the existing framework until we can migrate completely.

The error I'm getting is:

Unit Test Adapter threw exception:
Could not load file or assembly 'ArtOfTest.Common, Version=2010.3.1307.0, Culture=neutral, PublicKeyToken=14a0200bfcbb7b62' or one of its dependencies. The system cannot find the file specified..

I don't quite understand what could be the problem. The file in error is still in the same place as it was before the trial install. 

I'm using
Visual Studio 2010
ArtofTest WebAii
Microsoft Test Tools
Silverlight UI testing

Hi Sandy,

WebAii framework is part of Test Studio, so you can continue executing your test on the framework. You can resolve your problem easily by removing the "ArtOfTest.Common.dll" assembly reference and rebuild your projects, This is needed because the assembly is no longer included in Test Studio and its functionality is transferred to "ArtOfTest.WebAii.dll".

Ok, so I could have my older tests referencing the same up to date framework that Test Studio installed. That would require a little code cleanup since some initialization settings referenced using the old framework are obsolete in the new framework.

I was thinking I could simply launch the older tests "as is" since that framework is installed in a completely different folder and the project references the files in that location.

Hi Sandy,

That is correct. There is no way to use the old  framework and the new framework on the same machine. While installing Test Studio is deleting all old references from the Global Assembly Cache(GAC), no matter the two frameworks are in different folders. 
 
I am sorry for the inconvenience.
