Agent Version and Platform

Version of your agent? 2.134.2

OS of the machine running the agent? Windows 10, 1803

The agent-machine has VS2017 Professional installed.

VSTS Type and Version

VisualStudio.com

What's not working?

I use "Visual Studio Test Platform Installer (Preview)" and "Visual Studio Test (v2)" to run my tests. I enabled Code Coverage for them.
The codecoverage.exe files are located at

C:\vstsAgent\_work\_tool\VsTest\15.8.0-preview-20180510-03\x64\tools\net451\Team Tools\Dynamic Code Coverage Tools\CodeCoverage.exe
C:\vstsAgent\_work\_tool\VsTest\15.8.0-preview-20180510-03\x64\tools\net451\Team Tools\Dynamic Code Coverage Tools\amd64\CodeCoverage.exe

but the logs tell me

...

If I run the same tasks on a VSTS Hosted Agent the coverage works.

@SeriousM can you please provide the build/release logs with system.debug=true.
Please upload the entire zip file you get.

Also in the vstest task have you set the test platform version to installed by tools installer?

Also in the vstest task have you set the test platform version to installed by tools installer?

That was the solution. It was set to "Latest" which suggested to select a special version, not a result of a preview executed task.
Thank you. Maybe this could be enhanced to be set automatically or suggested if CodeCoverage.exe wasn't found?

@SeriousM thank you for your feedback. @PBoraMSFT for taking a look at the feedback.

+1 I reproduced this with same version of agent and VS installed

@jairov4 - Code coverage does not ship in VS Professional edition. You need to use VS Enterprise or use the test platform installer task.

I used Visual Studio Test Platform Installer task like this. however I still face dll not loading exception when i try to access it from the runsettings

1. VSTPI task before running the VsTest task using the runsettings

- task: VisualStudioTestPlatformInstaller@1
displayName: 'Visual Studio Test Platform Installer'
inputs:
versionSelector: specificVersion
testPlatformVersion: 16.10.0"

2. runsettings file

<?xml version="1.0" encoding="utf-8"?>
