VSTS "Visual Studio Test" task deletes TRX file after publish

I've inherited a jacked VSTS build process and I'm attempting to integrate SonarQube into the mix. Jacked, in that it isn't a clean install and I know the previous owner has done some strange and mysterious things with it that I haven't been able to track down yet.

Anyways, the problem I'm having is that the "Visual Studio Test" task step is deleting the .trx file after publishing the results. I need the .trx file for SonarQube. I can see the trx file is being deleted and after a screen recording of the folder and the active console logging of the VSTS build process pinpointed the publish process where the .trx file disappears. With system.debug = true here are a subset of the logs (the .trx file disappears somewhere in here):

Test results remaining: 165. Test run id: 33.

Updated test results: 165
Publishing Attachments: 2
Entering CreateTestRunAttachmentsAsync
Leaving CreateTestRunAttachmentsAsync

Completed PublishTestResult
Completed Publish Test Results: 0

I've tried a number of things, the latest of which was to install the latest VS 2017 Enterprise IDE to the build machine and am using these settings in the task:

Not sure if this helps but here is an approximation of the vstest call the above makes as shown in the console:

vstest.console.exe /TestCaseFilter:"FullyQualifiedName=<all the dlls in my solution>"
"C:\agent\_work\2\s\Source\Sln\Project1\bin\Debug\net461\Project1.Tests.dll"
"C:\agent\_work\2\s\Source\Sln\Project2\bin\Debug\net461\Project2.Tests.dll"

/diag:"C:\agent\_work\_temp\4acf64a0-4b51-11e8-9bf5-3b4a52af383b.txt"

-#############################

If I run vstest.console.exe from the command line, the results aren't published and the .trx file isn't deleted.

-#############################

I'd like the Visual Studio Test task step to publish but not delete the .trx file.

Any help would be appreciated. Thanks!

Solution

I can also reproduce the result.

For VS Test task with the version 2.*, it will delete the .trx file after executing VS Test task.

If you need to get the .trx file after VS Test task, you can use VS Test task with the version 1.*. It will keep the .trx file in the source directory.
