I working on a new non-XAML TFS build. My objective is to build the test project on our build agent VM, copy the test binaries to our test agent VM and execute our Selenium web UI tests from the test agent VM.
My build definition process looks like this:
- Get Sources
- NuGet Installer
- MSBuild (builds test project)
- Windows Machine Copy (copies test project bin folder contents to test agent VM)
- Visual Studio Test Agent Deployment (deploy test agent to test agent VM)
- Run Functional Tests
At this point, when I kick off a build, all steps as far as and including Visual Studio Test Agent Deployment are completing successfully.
However, when the Run Functional tests task begins execution, we are seeing the following console output:
Preparing task execution handler.
Executing the powershell script: D:\tfsbuild-2_work_tasks\RunVisualStudioTestsusingTestAgent_d353d6a2-e361-4a8f-8d8c-123bebb71028\1.0.52\RunDistributedTests.ps1
DistributedTests: Environment WinRm Protocol HTTP.

DistributedTests: build id: [build id]
DistributedTests: test configuration mapping:
DistributedTests: Test Run with Id [run#] Queued
DistributedTests: Test run '[run#]' is in 'InProgress' state
The Run Functional Tests task continues to attempt execution until time-out, showing DistributedTests: Test run '[run#]' is in 'InProgress' state in the TFS console output.
The DTAExecutionHost.exe log file shows the following entries for each corresponding console output:
DTAExecutionHost.exe Information: 0 : TestExecutionServiceCommandQueueListener.DispatchAsync : Getting Command for Test Agent 19 DateTime=2018-07-19T14:36:27.6387445Z

In my Visual Studio Test Agent Deployment task, selected protocol is HTTP, the Run UI tests checkbox is ticked, Update test agent checkbox is unticked.
During Visual Studio Test Agent Deployment task, blank DTAExecutionHost.exe console window opens on the test agent VM; this window remains open for the duration of the test run attempt.
All tests in the project are discovered and execute as expected in Visual Studio on local machine.
I have read a number of blogs, posts, discussion threads on this issue in recent days but have so far been unable to find a resolution to the problem. Please assist; any and all insights and suggestions welcome.
UPDATE: 21 August 2018
This issue persists. Answer provided below appeared to fix problem but issue returned, intermittently at first (I have had successful executions), now timing out on test execution step for every build.
I've unmarked the answer below as correct.
