ravispr4 · September 6, 2023, 1:30pm

Hi,

code coverage result were working fine on Window(showing result both on Azure devops UI and sonarcloud as well) but not on Linux (only showing on Azure devops UI but not on sonarcloud)

We choose AGent as Ubuntu

Prepare analysis :
sonar.exclusions=/obj/,**/.dll*
sonar.cs.opencover.reportsPaths=$(Build.SourcesDirectory)/coveragereport/.xml*
sonar.cs.vstest.reportsPaths=$(Agent.TempDirectory)/.trx*

Dotnet test
Argument : –collect:“XPlat Code Coverage”

script :
dotnet tool install -g dotnet-reportgenerator-globaltool

reportgenerator -reports:$(Agent.TempDirectory)//coverage.cobertura.xml -targetdir:$(Build.SourcesDirectory)/coveragereport -reporttypes:‘HtmlInline_AzurePipelines;Cobertura’*

publish code coverage :
Summary file : $(Build.SourcesDirectory)/coveragereport/Cobertura.xml
report directory : $(Build.SourcesDirectory)/coveragereport

after execution of pipeline shows the result:
dotnet test result -
Starting test execution, please wait…
A total of 1 test files matched the specified pattern.

Hey there.

Take a look at this thread:

Hi @Colin,

FYI, I am using classic editor
And I have tried it but giving error for opencover format.

Please help where and what I am missing to get the opencover format result ?

Colin · September 12, 2023, 9:02am

It looks like the report generator you’re using only supports generating opencover in the pro edition (GitHub - danielpalme/ReportGenerator: ReportGenerator converts coverage reports generated by coverlet, OpenCover, dotCover, Visual Studio, NCover, Cobertura, JaCoCo, Clover, gcov or lcov into human readable reports in various formats.)

Have you tried the other coverage report generators mentioned in the docs?

Hi Colin,

I just tried with below changes and its working

Prepared analysis
sonar.exclusions=/obj/,**/.dll*
sonar.cs.opencover.reportsPaths=$(Agent.TempDirectory)//coverage.opencover.xml*
sonar.cs.xunit.reportsPaths=$(Agent.TempDirectory)/.trx*
sonar.verbose=true

dotnet test
–collect:“XPlat Code Coverage;Format=opencover”

Publish code coverage
$(Agent.TempDirectory)//coverage.opencover.xml*

on execution of pipline
dotnet test

publish code coverage

run cod analysis

Here I was trying to publish the code coveage to opencover format and it showing the code coverage result on sonarcloud.
–collect:“XPlat Code Coverage;Format=opencover”

Any inputs or suggestions please on the approach above ?

Colin · September 14, 2023, 9:01am

Hey there.

I’m not quite sure what the status is based on your post.

So… it’s working now? Is your coverage displayed in SonarCloud?

rkundeti · September 14, 2023, 9:39am

yes its working and showing the coverage result on SonarCloud

Hi Colin,

Suggest me the approach I am following is correct or not ?

Thanks

Hi Colin,

If you code coverage is being imported correctly, yes, I suggest that the approach you’re following is correct!
