Must-share information (formatted with Markdown):

  • I am using SonarQube 8.9.10.61524
  • Trying to show code coverage % and Unit Test count in Sonarqube Portal
  • Configured Project in sonarqube, able to see Bugs, Code smells etc.
    Project implemeted in .Net 6.0 version using VS2022

Ran belwo commnds to generate report in xml format.

  1. dotnet sonarscanner begin /k:“VCA.AW.API.NUnit” /d:sonar.host.url=“http://localhost:9000” /d:sonar.login=“cae19b65a2cc04bd9eee8168e1b7fba3b37d91e5”
  2. dotnet build
    3.dotnet test --collect “Code Coverage”
  3. dotnet sonarscanner end /d:sonar.login=“cae19b65a2cc04bd9eee8168e1b7fba3b37d91e5”

By doing this, i am able to generate reports for Type ‘Code Coverage XML file’

Tried in another way using OpenCover, ran below command to generate reports

1.dotnet sonarscanner begin /k:“VCA.AW.API.NUnit” /d:sonar.host.url=“http://localhost:9000” /d:sonar.login=“cae19b65a2cc04bd9eee8168e1b7fba3b37d91e5”
2.dotnet build
3. coverlet .\VCA.AW.API.UnitTest\bin\debug\net6.0\VCA.AW.API.UnitTest.dll --target “dotnet” --targetargs “test --no-build” -f=opencover -o=“coverage.xml”
4. dotnet sonarscanner end /d:sonar.login=“cae19b65a2cc04bd9eee8168e1b7fba3b37d91e5”

By doing this covergae.xml getting created.

As per log, coverage.xml not getting from given path. But on hard disk its present.

Hi,

Can you provide your full analysis log?

The analysis / scanner log is what’s output from the analysis command. Hopefully, the log you provide - redacted as necessary - will include that command as well.

This guide will help you find them.

Hi,

I was able to display code coverage in Dashboard using below commands,

dotnet "C:\sonar-scanner-msbuild-5.10.0.59947-net5.0\SonarScanner.MSBuild.dll" begin /k:"VCA.AW.API.NUnit.New" /d:sonar.host.url="http://localhost:9000" /d:sonar.login="eeb355e2638249b2c16b71c362df6e94ab356196" /d:sonar.cs.opencover.reportsPaths="D:\VCA Projects\AppointmentWaitlistAPI_NUnit\VCA.AW.API\VCA.AW.API.UnitTest\**\TestResults\*\coverage.opencover.xml" /d:sonar.cs.xunit.reportsPaths="D:\VCA Projects\AppointmentWaitlistAPI_NUnit\VCA.AW.API\VCA.AW.API.UnitTest\**\TestResults\TestOutput.xml"

dotnet build "D:\VCA Projects\AppointmentWaitlistAPI_NUnit\VCA.AW.API\VCA.AW.API.sln" -nr:false

dotnet test --no-build "D:\VCA Projects\AppointmentWaitlistAPI_NUnit\VCA.AW.API\VCA.AW.API.UnitTest" --logger:trx;LogFileName="D:\VCA Projects\AppointmentWaitlistAPI_NUnit\VCA.AW.API\VCA.AW.API.UnitTest\TestResults\TestOutput.xml" --collect:"XPlat Code Coverage" -- DataCollectionRunSettings.DataCollectors.DataCollector.Configuration.Format=opencover

dotnet "C:\sonar-scanner-msbuild-5.10.0.59947-net5.0\\SonarScanner.MSBuild.dll" end /d:sonar.login="eeb355e2638249b2c16b71c362df6e94ab356196"

but dealing with another issue for Unit Test count. I have written Unit Test cases for my code. After deployment in Sonarqube, Unit Test count always showing 0.
Not sure how to resolve this problem. I am using NUnit for Unit Test cases. I really appreciate if someone can provideany solution or any inputs on this.

Hi Nitin,

Congrats on working through getting your coverage reported. Showing Unit Test count is a different question, and deserves a different thread.
