Visual Studio 2010/2012 - Exceptions occur for Test Agent service when running automated test cases on remote machine

Question

I am currently in the process of setting up an automated test case solution for a project, and I am using Visual Studio 2012, Test Manager 2010, Test Controller 2010 and Test Agent 2010. The TFS Server I am using is 2010, and our automated test case project is in the .NET 4.0 framework.

The setup approach for our automated test case solution is:

-We have a remote machine with the Test Controller and Test Agent installed on them -Test Manager is configured with a physical environment (in the lab center) that uses the Test Controller and Test Agent on the remote machine -The Test Settings in Test Manager are also configured to run the tests for a 64 bit machine, which is how the remote machine is configured -Test cases are then linked with Coded UI tests from our automation solution, executed from Test Manager, which are then run on the remote machine

While I have had success with this setup for automation solutions in Visual Studio 2010, I have encountered a number of issues when trying to work with the 2012 version of the solution.

The latest issue I have run into is that, while I am able to execute the test in Test Manager and have it queue up in the Test Agent on the remote machine, the test never executes.

Looking at the Event Log, I am seeing 3 exception errors that are occurring, 1 for the VSTTAgent and 2 for the VSTTAgentProcess. I have attached each of the errors below in their respective order.

Has anyone encountered an issue like this before? Any help would be very much appreciated, and I thank everyone in advance.

Answer 1

Per my comment under the first question, and to Andrew's answer, I discovered that the 2012 agent and controller can't be used with TFS 2010.

As some additional information, I found that our company's build agent (2010) didn't have all of the class library definitions we needed to deploy our 2012 solution properly anyway.

I appreciate everyone's answer to my question, and I hope this helps someone else in the future!
