Code Coverage–part 25

Install coverlet and report generator

dotnet tool install coverlet.console

dotnet tool install dotnet-reportgenerator-globaltool

 

Then

dotnet coverlet Infovalutar.sln –target “dotnet” –targetargs “test InfovalutarTest\InfovalutarTest.csproj –configuration release –no-build” –format opencover –exclude “[xunit*]*”

dotnet reportgenerator “-reports:coverage.opencover.xml” “-targetdir:coveragereport” “-reporttypes:HTMLInline;HTMLSummary;Badges”

 

And the result ?No assemblies have been covered.

Updating all NuGet packages for the solution  – including a collector for coverlet.

Reading more, discover it works with

dotnet test –collect:”XPlat Code Coverage”  -r resultsFolder

The problem is that generates a GUID inside resultsFolder … and reportGenerator cannot be pointed to a random folder

Playing with different options, such as

dotnet test /p:CollectCoverage=true /p:CoverletOutput=’results’ /p:CoverletOutputFormat=json -v n

No results in the results directory…

Found obscure reference https://github.com/tonerdo/coverlet/issues/201 that I need to add package coverlet.msbuild

Now

dotnet test –configuration release –no-build  /p:CollectCoverage=true /p:CoverletOutputFormat=cobertura -v m /p:CoverletOutput=cob.xml

dotnet reportgenerator “-reports:InfovalutarTest/cob.xml” “-targetdir:coveragereport” “-reporttypes:HTMLInline;HTMLSummary;Badges”

 

And generates report.

And because I want those to be added in AzureDevOps at test I add –logger trx  and https://docs.microsoft.com/en-us/azure/devops/pipelines/tasks/test/publish-test-results?view=azure-devops&tabs=yaml

– task: PublishTestResults@2
inputs:
testRunner: VSTest
testResultsFiles: ‘**/*.trx’

– task: PublishCodeCoverageResults@1
inputs:
codeCoverageTool: cobertura
summaryFileLocation: ‘**/cob.xml’

It works! Last: going to shields.io to have a display of the tests
