Test Coverage not show in Sonar entegration in .netcore 3.2

Question

I want to integrate Sonar integration into my .netcore 3.2 project.

I did it but test coverage was not shown in Sonar.

My docker sonar integration looks like this:

# install nodejs
RUN curl -sL https://deb.nodesource.com/setup_11.x | bash - && apt-get install -y nodejs autoconf libtool nasm

ENV SolutionName  MyProject
# reviewing this choice
ENV SONAR_SCANNER_MSBUILD_VERSION 4.8.0.12008

ARG branchName
RUN wget https://github.com/SonarSource/sonar-scanner-msbuild/releases/download/$SONAR_SCANNER_MSBUILD_VERSION/sonar-scanner-msbuild-$SONAR_SCANNER_MSBUILD_VERSION-netcoreapp3.0.zip
RUN apt-get update && apt-get install -yy unzip 
RUN unzip sonar-scanner-msbuild-$SONAR_SCANNER_MSBUILD_VERSION-netcoreapp3.0.zip -d /sonar-scanner
# Install Sonar Scanner

RUN rm sonar-scanner-msbuild-$SONAR_SCANNER_MSBUILD_VERSION-netcoreapp3.0.zip
RUN chmod +x -R /sonar-scanner

# Sonar scanner start
RUN dotnet /sonar-scanner/SonarScanner.MSBuild.dll begin /d:sonar.host.url=http://sonar.mycompany.com /d:sonar.login=111111/k:$SolutionName:"$branchName" /n:$SolutionName:"$branchName" /v:1 /d:sonar.cs.opencover.reportsPaths="/app/tests/MyProject.Tests/coverage.opencover.xml"
RUN dotnet test ./tests/CustomerServices.Tests/MyProject.Tests.csproj /p:CollectCoverage=true /p:CoverletOutputFormat=opencover 
RUN dotnet publish ./src/MyProject.Api/MyProject.Api.csproj -o /publish
RUN dotnet /sonar-scanner/SonarScanner.MSBuild.dll end /d:sonar.login=111111
# Sonar scanner end

This integration shows bugs, code smells and quality gates but does not show coverage.

I also install coverlet.msbuild on my test project for test coverage but there is still no test coverage on my Sonar screen.

My Jenkins build like this.

Test Run Successful.
Total tests: 684
     Passed: 684
 Total time: 9.9564 Seconds

Calculating coverage result...

How can I integrate Sonar for test coverage?

Answer 1

you need to pass the dotnet test command before sonar scanner begin command because with dotnet test command we are generating the report with coverage.opencover.xml uisng the /p:CollectCoverage=true /p:CoverletOutputFormat=opencover
