Hello,

I have setup dotnet sonarscanner for my opensource project, in the build log it says that it picked up the report:

INFO: Adding this code coverage report to the cache for later reuse: /home/runner/work/UMVC/UMVC/UMVC.Core/./dotCover.Output.html
INFO: Sensor C# Tests Coverage Report Import [csharp] (done) | time=3ms

You can see the log at: UMVC.Core SonarCloud Analysis

The tutorial what I have followed: Using dotcover and SonarCloud

Hello

We have a guide for trouble shooting code coverage import - did you read it?

8

Hi @Andrei_Epure I have read the trouble shooting guide but is not working the file dotCover.Output.html seems to be uploaded but no coverage is displayed on SonarCloud

9

I have also tried to use dotnet-coverage instead of DotCover from jetbrains but it has no effect

Hi @loic-lopez,

Thanks for your feedback!

Unfortunately the build logs are no longer present. Would it be possible to do another run with verbose logging enabled (/d:“sonar.verbose=true”) and send us the logs? Additionally, could you please share with us the generated coverage file?

Best,
Costin

Hi @costin.zaharia, thanks for your reply,

See the pipeline log here : Update unity to 2021.3.16f1 & fix coverage · loic-lopez/UMVC@980ecc7 · GitHub

There is something strange in the logs :

More about the report processing at https://sonarcloud.io/api/ce/task?id=AYX0nGmxJjozFjgcJLC3

if you click on this link it says {"errors":[{"msg":"Project doesn\u0027t exist"}]} but UMVC.Core project exists in SonarCloud : https://sonarcloud.io/dashboard?id=UMVC.Core&pullRequest=61

Hi @loic-lopez,

I’m sorry for my delayed response.

I’ve checked the logs and, from what I can tell, either the generated coverage file coverage.xml does not contain the needed information.

Begin step configuration:

Extract from the end step:

Would it be possible to share the content of this file with us? you can upload it as a build artifact, or modify the build to it’s content during the job

Thanks,

Hi Again, sorry for the delay you can find at the address bellow this message the coverage.xml file given by dotnet test runner:

https://github.com/loic-lopez/UMVC/suites/13030419276/artifacts/706037512

Thanks for sharing the file with us. I’ve taken a look and it doesn’t contain any relevant information. There is just a list of skipped modules. This problem does not seem related to Sonar products.

Could you please check the coverage tool configuration and also how it is called?

Thanks for your reply,

The pipeline is: Update unity to 2021.3.16f1 & fix coverage by loic-lopez · Pull Request #61 · loic-lopez/UMVC · GitHub

And I use this live to generate coverage:

dotnet-coverage collect 'dotnet test' -f xml  -o 'coverage.xml'

which is enclosed by:

dotnet sonarscanner begin

and

dotnet sonarscanner end
21

OK. What happens if you run the same command for code coverage without enclosing it by the scanner begin and end steps? If it’s still containing only the list of skipped modules the problem is not in the scanner.

22

Thanks for reply and sorry for wasting your time, the issue was the tests are run in a ubuntu-latest runner on github so I switched to windows-latest and now the coverage file has no more skipped modules.

I don’t know why skipped modules are only generated on ubuntu.

No worries. Thanks for your reply. The problem was not the presence of the skipped modules, was the lack of relevant information about the covered code.

It’s interesting that dotnet-coverage collect works, for your solution, on windows but not on ubuntu.
