Visual Studio Test Run: Run Coded UI automated tests from test plans in the Test hub

Question

Build Definition

I am using the same machine as Build and Release configuration. I have created build successfully. Using build I am able to execute Coded UI scripts in Visual Studio Test Task in build and they are working fine My configuration is for build definition is mentioned below

Release Destination

after successful build definition and execution of test scripts, My next plan is to Run Automated Tests from Test plans in the Test Hub. I have associated my test scripts with Test cases also. Please have a look at the image of my release definition where I have selected Test Run using the Test run

Notification I receive after failed execution of automated test from test plan in test hub is

Deployment of release Release-11 Rejected in Deploy Test Scripts.

I added debug variable and it seems that when creating a setting file, it is something like system.io exception.

I will be thankful to you if anyone can identify where I am missing something or what I need to fix this issue so that I can execute automated tests from test plans in the test hub.

Answer 1

Based on the error message "Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host." and your clarification. It should be related to the known issue on win server 2008 R2. Please refer to below article for details:

Team Foundation Server: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.

However the bug has been fixed by the Windows team and they have released a QFE for it. You can find the QFE here. You will need to install it on all of your ATs.

So, just try to install the hotfix and restart the computer after you apply this hotfix, then try it again.

You can also try to use the initial workarounds that list in the blog:

1. Open the IIS Manager
2. In the Connections pane, make sure the name of your AT is selected.
3. In the middle pane (titled “ Home”), make sure you are in the “Features View” (bottom) and scroll down to the Management section.
4. Double-click the “Configuration Editor” icon.
5. The middle pane should now have the title “Configuration Editor”. In the Section pull down near the top, expand the system.applicationHost and select “webLimits”.
6. You should now see a bunch of property value pairs, one of which is named “minBytesPerSecond”. Its value is most like 240. You will want to lower this value for the workaround.

Besides, another possibility is that it's caused by the Proxy server, just try to bypass the proxy server, then check it again.
