I am trying to integrate WPF application functional tests into TFS CI and this works only partly.
In TFS Build Definitions there are steps Visual Studio Test Agent Deployment and Run Functional Tests. The agent is configured to run as interactive process. Everything works only when someone is logged into the testing server and actually sees the screen. Once you log out from the server, then CI gets stuck on the task ConfigureTestAgent of Deploy TestAgent step (see logs below).
The agent runs under same credentials as used to RDP to the testing box. What exactly is failing there - communication to TFS server or something else?
Functional tests get stuck with the following console log:

This issue usually happens when the group policy on the machine resets the Autologon registry key required for test execution, while the deploy test agent step tries to set this registry key.
For Test agent to run interactively, we need to have a valid user session on the box and if that session is not present then via autologon to create that session.
So, please check if you have enabled the autologon for your test machine, or any group policies restrict the autologon.
Please try below things to narrow down the issue:
If you have successfully performed the test before, just try to reboot the test machine and uncheck ‘Update Test Agent’ under “Advanced” (by default it’s selected and forces to reinstall TA everytime).
If not performed before, you could try to download the test agent 2015, then install it on that machine manually and check the result.
If that doesn't work, then try:
On the other hand, you may try to find another test machine to test if test agents can be deployed well on it.
