VSTest task with code covereage enabled fills up disk with IntelliTrace files

[ChristopherHaws]

Environment

• Server - VSTS (I can email you account/build details if need be, but I cant post it on a public forum)
• Agent - Private
  • OS: Windows Server 2016 (10.0.14393)
  • Agent Version: 2.129.0

Issue Description

When using the VSTest Task with CodeCoverage enabled, IntelliTrace logs get placed into the %WINDIR%\temp\ directory and do not get cleaned up. Our C:\Windows\Temp directory was using over 100GB due to .itrace files. During the build I was able to locate a file in F:\vsts\builds\a1\_temp called IntelliTrace_Logging_History_15.0_intellitrace_00002bb0_01d3bb24c81e8e1d with the following content:

<LoggerInfo xmlns="urn:schemas-microsoft-com:visualstudio:tracelog" name="intellitrace_00002bb0_01d3bb24c81e8e1d" logPath="C:\Windows\Temp\testhost.x86_00002bb0_180313_234117.iTrace" processId="5556" creationTime="0" sessionId="0" keepAlive="false" collectionPlanPath="">
  <ClientInfo id="0" creationTime="0" sessionId="0" name="" processBitness="0" clrVersionMajor="0" commandLine="" />
</LoggerInfo>

Here is the yaml of our VSTest task, and we have no custom build variables:

steps:
- task: VSTest@2
  inputs:
    testAssemblyVer2: '**\MyProject.Tests.dll'
    vsTestVersion: 15.0
    runInParallel: true
    codeCoverageEnabled: true
    platform: '$(BuildPlatform)'
    configuration: '$(BuildConfiguration)'
    rerunFailedTests: false

Error logs

There are no errors occurring other than disk full errors when the disk runs out of space.

@ChristopherHaws Thanks for reporting the issue, We have fixed
the issue, microsoft/vstest#1483. Fix will be available in VS 15.7

@ChristopherHaws, this has been fixed and is pending release. It should be available around next week. Can't commit to a date yet. You can get the latest vstest platform by using the test platform tools installer task.

You can monitor the nuget package for the new version which should have the fix @smadala made.
The current version is 15.7.0-preview-20180307-01, the next update around next week should have it,

Closing this issue now. Please reopen if you need more assistance with the tools installer task or if in the next release this issue still persists.

@smadala, @ShreyasRmsft, this issue also happens when running tests from Visual Studio on the developer machine. It is also fixed in Visual Studio? Or the fix is for TFS Task only?

Thanks

[smadala]

Yes, Fixed in both.

@ShreyasRmsft, when you say it will be available next week, it will be a RTM version? Or 15.7 Preview 2?

Thanks

@ChristopherHaws, @fujiy It will be available for VSTS next week.

But you'll have to wait longer for the VS RTM release where this will be fix will be released for the IDE as we do not have the convenience to shipping as and when we want. But for VSTS we can and the fix will be out via the nuget package as I have specified above.

[smadala]

Fix available in https://www.nuget.org/packages/Microsoft.TestPlatform/15.6.2 .
We are planning to fix this issue in VS 15.6 upcoming update.

I am seeing a buildup of .itrace files in VSTest version 16.2.0. I'm using Agent version 2.155.1 x64 on Windows Server 2016.

[Edit]: Tested with VSTest 15.7.0, and it seems to be a problem here as well. Just a thought, but we are running the agent interactive and also as administrator, so the problem could be somewhere there.
