Code Coverage is not shown in the SonarQube

[RaptoR (Victor)]

Hi!

I have SonarQube installed on a Windows agent in Jenkins.

I want to see code coverage percentage and unit tests in SonarQube. I used the official documentation for all the commands.

Here is my example:

withSonarQubeEnv(credentialsId: 'mycred', installationName: 'SonarQube') {
    def scannerHome = tool 'SonarScanner'
    bat "dotnet ${scannerHome}\\SonarScanner.MSBuild.dll begin /k:\"${proj_key}\" /d:sonar.host.url=\"${env.SONAR_LINK}\" /d:sonar.cs.opencover.reportsPaths=\"tests\\TestResults\\*.xml\" /d:sonar.cs.vstest.reportsPaths=\"**/*.trx\" -v:diag"
    bat "dotnet build --no-incremental"
    bat "dotnet test /p:CollectCoverage=true /p:CoverletOutputFormat=opencover /p:CoverletOutput='./TestResults/'"
    bat "dotnet test --collect:\"XPlat Code Coverage\""
    bat "dotnet ${scannerHome}\\SonarScanner.MSBuild.dll end"
}

In Jenkins, a folder tests\\TestResults is created, where I see test_results.trx, and it shows me the tests in SonarQube - there are no problems with that.

For code coverage, two files are created:

• tests\TestResults\c377z55b-poq3-421e-8bad-0dc790a2841cAdministrator_JENKINS-AGENT_2024-04-10.12_57_33.coverage and
• tests\TestResults\c117f25b-fbc3-421e-8bad-0dc593f2839b\coverage.cobertura.xml

I don’t understand which of these files should be passed to SonarQube and how to display the percentage there?

SonarQube works only with one branch for me. Please advise.

Hey there.

As noted in the template post, what version of SonarQube are you using?

And, what do the logs say about importing code coverage?

How to find logs about importing code coverage

When coverage data isn’t appearing as expected in SonarQube / SonarCloud, the first place you should look is the scanner logs. Where do I find the scanner logs? This will likely be broken out into its own guide soon The Scanner logs are the output of executing one of the scanners, either directly or wrapped by one of many integrations, such as the SonarScanner for Jenkins, SonarScanner for Azure DevOps, SonarQube/SonarCloud GitHub Actions or SonarQube / SonarCloud Bitbucket Pipes. …

Hi,
SonaQube version is * Community Edition* Version 10.3 (build 82913)
SonarScanner for .Net 6.0.0

Thanks!

How is that SonarQube.xml file getting generated? I wouldn’t expect it to be the output of these commands (the name isn’t specified anywhere)

@RaptoR

    bat "dotnet test /p:CollectCoverage=true /p:CoverletOutputFormat=opencover /p:CoverletOutput='./TestResults/'"
    bat "dotnet test --collect:\"XPlat Code Coverage\""

First things first, if this file isn’t expected, I would make sure it stops getting generated. Don’t forget to check if it somehow got checked into your repo as well.
