Closed NDDeveloper13 closed 1 year ago
@NDDeveloper13 transferred the issue to the vstest repo because this seems like an issue with the testplatform rather than the task.
What is the status of this one? This is affecting our regression in a big way. We haven't had a clean regression in months due to this issue. Do you need more information and log files?
@pavelhorak @nohwnd - looks like this is a blocking issue for teams. Please take a look.
@NDDeveloper13 Could you please provide more logs, which you mentioned in Task logs section, you can send it to my email which is in my profile.
By first look, does not seem like a issue with Test Platform as this exception says : System.IO.IOException: Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host and HKEY_LOCAL_MACHINE\EnterpriseTools\QualityTools\TestTypes
- it is unable send data to testhost. You can try to reinstall agents for now.
@Sanan07 That connection error is mostly suggesting that testhost crashed, or was forcibly aborted so heartbeat request cannot be finished because the channel between the two processes was closed. That error usually does not suggest anything about the real cause.
@NDDeveloper13 Please also look at this solution provided by issue creator, maybe it or something close to that solution can help you : https://github.com/microsoft/vstest/issues/2490
@nohwnd reassigning to you, as you recently investigated it (in mail thread)

Enter Task Name: Visual Studio Test - v2
Environment
Server - TFS on-premises 17.153.29522.3
Agent - Private: Windows 10, Azure Pipeline Agent 2.164.7, Visual Studio Test Task 2.153.9, Microsoft TestPlatform 16.5.0
Issue Description
We have a test run that includes 133 test points that runs across 8 agents. It consistently has issues each time it runs. Multiple agents hang during the test run and are unable to complete tests. They continue to show as In Progress until they eventually abort or we kill them manually. I cannot find consistencies on any specific test agents that are causing the issue nor any specific test points. Sometimes it's just 1 agent that has the issue, sometimes up to 4 or more. In the screen shot below, 2 agents have the issue.

I would prefer not to post the logs here. Please provide a way for me to send them to you directly.
