Unit Test Adapter threw exception: Method not found

Question

I'm getting the following error when trying to run a coded ui test from MTM:

Unit Test Adapter threw exception: Method not found: 'Void Microsoft.VisualStudio.TestTools.UITest.Extension.UITestUtilities.AddAssemblyResolveHandler()'..

All I'm looking for is a hint as to why this is happening, my project references look like this:

I'm using Visual Studio 2013 Update 4, The Test Controller and Agent too are 2013 Update 4.

I can queue a build, but when I try and run a test against the build using MTM, I get this error.

EDIT, Also using net 4.5.1.

EDIT 2: Everything runs locally in dev environment when tests are kicked off from Visual Studio. It's once I kick off the tests through MTM -> Controller -> Agent where the problem persists. The exact same message is thrown regardless of the test.

Answer 1

Check if the test run has all the necessary dlls in the test run directory, in the machine where test controller runs check the directory "C:\Users\ username \appdata\Local\VSEQT\QTController\ testrunid \Deployment\"
