Build-Deploy-Test Workflow does not reach Test Agent - deployment

Question

at First im New to automated Tests with TFS, so i try actual many Things with try on Error.
But I Hope you can give me some Ideas What i perhaps do wrong.
I have set up a Environment in Microsoft Test Manager like described in serveral Blogs from MSDN. http://msdn.microsoft.com/en-us/library/hh873102.aspx#Prerequisites for example.
My Infrastructure is as follows: The Build Server and Test Controller are on the Same Machine (Win2012) but my Test Agent(Win2008R2) is an other Machine. Everything is TFS 2013 or VS 2013 Update 3.
I have a Build definition which builds the Tests on the Buildserver into a specified Dropfolder. This is working fine. And a Second Build Definition which uses the LabDefaultTemplate.11 for working with the Environment. Within i specified the Environment, the other Build Definiton a Deployment Script and also my Testplan with the associated Automated Tests.
But if i try to Start my Build-Deploy-Test Workflow i have got two outcomes.
First, without specifed a Deploment Script the Workflow Reaches Test Run and the Workflow became endless (It runs 16 Hours) then i aborted it.
And Second i specified the Deployment Script and now it seems i get the same but on the Deployment Step. I let it Run for almost 20 Minutes and i watched my Agent on VM Console.
All i saw is that he sometimes Disconnected for a short moment and then was Online again.
Now I'm Asking, why this Build Workflow could becomes endless?
The Tests would be CodedUiTests.
Here the Log of the last Run i stopped:
20:37 Overall Build Process

If you would need more specific informations please leave a Answer with the needed Things, and i will care about it, but i actual do not know what you could need and don't want to overfill this Question
Edit Dec 16th 2014:
Here the requested Details:
Deploying Build 00:30:00
Run Deployment scripts 00:30:00
Inputs
Values: Win2008R2TA02 | $(BuildLocation)\Uitest\deploymentScript.cmd $(BuildLocation)
Run Deployment Task00:30:00
Inputs
UseRoleForDeployment: False
MaxWaitTime: 00:30:00
ThrowOnError: True
BuildLocation: \\BuildServer\TFS Build\UiTest.Dev.Build\UiTest.Dev.Build_20141216.1
LabEnvironmentUri: vstfs:///LabManagement/LabEnvironment/11
DeploymentScriptDetails: Win2008R2TA02 | $(BuildLocation)\Uitest\deploymentScript.cmd $(BuildLocation)
The Deployment Script i found in the Internet, but i thought this could be working.
REM set build path
set buildlocation=%1
REM set deployment path
set targetdir="C:\deploy"
REM create deployment directory
if not exist %targetdir% (cmd /c mkdir %targetdir%)
REM copy build to the deployment directory
xcopy /c /y /e %buildlocation%\*.* %targetdir%
REM if you are using a deployment package you can run it here, after you copy it to your deployment directory
And i Call it as follows:
$(BuildLocation)\Uitest\deploymentScript.cmd $(BuildLocation)
In the Eventlog of the Test Controller there are some Errors Repeating while the Build is running:
Service Control Managar:
The Visual Studio Test Controller service terminated unexpectedly. It
has done this 1 time(s). The following corrective action will be
taken in 0 milliseconds: Restart the service.

I tried this solution but i does not helping and related to the Link i have no "Web Access" Folder to clear the Cache out.

I realy stuck on that Problem. Any Help would be very appreciated.

Answer 1

Ok, i found the issue.
The problem was a corrupt Visual Studio and MTM Installation on the Buildserver where also the TestController is installed.
If you stumble on this problem, try the following things.
- Are all Components on the same Version (in my case 2013 Update 3) Check also Agent and Controller (in it's Configuration Dialog you find a About Button)
- open the MTM on the Server and Check if it can switch between different testplans of the project (in m case that bring up an error, and thats why the Controller could not deliver the Cases to the Agent.)
if it is like in my case so try a uninstallation and reinstallation of Visual Studio and MTM
My order was to deinstall first MTM then VS after that install VS then MTM then the actual Update.

Answer 2

The build report log on visual studio is not that great. Have you checked the log on the tfs website? (build failed report -> diagnostics -> view log or on the website under builds -> definition -> diagnostics)
Have you set the timeout for the deployment script? 16 hours is a long time.
also can you link the deployment code to the script. Do you have any other tests that do run on the agent? Have you checked the login/password and deactivated the login screen on the agent because tfs has a problem accessing this.
