Team City Code Coverage and Unit Test results not showing on Sonar

Question

I am trying to upload Unit Test and dotCover Code Analysis results from TeamCity to Sonar server. It shows code coverage and unit test results in the TeamCity but no code coverage/unit test on Sonar.

TeamCity Unit test step:

Followed by Powershell script:

I have the following additional parameter in Sonar Runner step:

Dsonar.cs.vstest.reportsPaths=TestResults.trc Dsonar.cs.dotcover.reportsPaths='%sonar.coverageReport%'

Does anyone know how to fix this?

Thanks.

Answer 1

Managed to fix the issue using the below script in step 3:

$Files= Get-ChildItem %system.teamcity.build.tempDir% ` 
    -Filter coverage_dotcover*.data ` 
    | where-object {$_.length -gt 50} ` 
    | Select-Object -ExpandProperty FullName 

$snapshot =[string]::Join(";",$Files) 

& %teamcity.tool.dotCover%\dotCover.exe merge ` 
  /Source=$snapshot ` 
  /Output=%env.TEMP%\dotCoverReport.dcvr` 


& %teamcity.tool.dotCover%\dotCover.exe report ` 
  /Source=%env.TEMP%\dotCoverReport.dcvr ` 
  /Output=%sonar.coverageReport% ` 
  /ReportType=HTML

What TeamCity version do you have? In TeamCity 9.1.1 there was a bug that caused test report files to be written in build temp directory. In this case Sonar plugin, that expects trx file to be in checkout directory, does not find it. There are several ways to solve it: the first is to upgrade to TeamCity 9.1.2 and above, the second is to pass absolute path to the report paths variable:

-Dsonar.cs.vstest.reportsPaths=%system.teamcity.build.tempDir%/TestResults.trc

The third way would be to pass absolute path, that points to checkout directory, to results file field of mstest runner:

%system.teamcity.build.checkoutDir%/TestResults.trc
