Load Test run won’t be able to start successfully and will get aborted with this error:
“The specified module could not be found”
This is known issue with Visual Studio 11 Beta. There is a simple workaround for this issue: Please install Test Agent on your Test Controller box as well and you are done. You need not to do anything extra like configuring installed Test Agent on Test Controller box etc. Just installing Test Agent on Test Controller will help in resolving above issue. There is no side impact of this workaround and it won’t take long also to install Test Agent on Test Controller also. This issue is fixed for later releases.
