Code coverage stays to 0%, what am I missing?

In a nutshell :

  • Error : SonarCloud Dashboard showing 0% Coverage
  • GitHub (private repo)
  • Github Actions
  • Python (for a data science project)

Hi folks,
I am a totally beginner with sonar source products, and I am in charge to configure SonarCloud automatic analysis on my team’s project (sic).

I have read all available documentations, everything is working fine, except that the code coverage on my project stays to 0. I have dug the documentation and some tutorials, but I am still stuck and cannot get what I am missing …

I run my unit tests using : pytest test --doctest-modules --junitxml=junit/test-results.xml --cov=jawclenching --cov-report=xml

Is there anything wrong in my configurations? my paths? my xml report format?

Let me know if you have any questions.

Have a nice day.

Please find my project’s configurations

Hi @Antoine_Lebaud , welcome to the community.

Maybe as a first investigation, could you try to turn on debug logging on the analysis (add sonar.verbose=true on the and see if you can see anything related to your coverage file being picked up or not ?


Hi Mickaël,

Thanks for your quick answer!

Correct me if I am wrong, but this part seems related to my xml report :

I have the same issue with GitLab CI.
Here I have posted my problem: Sonarcloud shows 0% coverage on new code, and also shows 0% coverage on master branch with gitlab ci - Stack Overflow

I appreciate any help


First, sorry for coming back to this thread so late. I figure you might have found the solution to your problem since you opened this thread. Should this not be the case, here is some additional information that may help.

We have published a new documentation on how to import coverage information for Python projects into SonarCloud, which you can find here.

Specifically in this case, you probably want to double check the paths in the coverage report. Those may not match with what SonarCloud is expecting, as the two steps are run in separate containers. When using, you can enable relative_files = True to avoid any mismatch. You can also use a sed command to fix this (as suggested in this StackOverflow thread).
