Need help figuring out why AZD code coverage % and SonarCloud code coverage %'s differ

SonarQube Cloud
1

We have a C# code base built in Azure DevOps, linked with SonarCloud. We’ve gotten the tests integrated correctly and things show up in SonarCloud correctly, except the code coverage. The % in AZD shows up as something like 85% with Cobertura, but when looking at the % in SonarCloud, it only shows 0.7%.

The SonarCloudAnalyze@1 log (attached) looks like it sees the .coveragexml file
SonarCloudAnalyze.txt (248.7 KB)

Here is my pipeline .yml file.
azd.yml.txt (2.2 KB)

Is there a setting or something I need to set in SonarCloud?

Hey there.

It does seem like the figures reported here (23 files, 15 files with coverage, 8 test files…) does fall short of your 129 files indexed.

What I would recommend is that you start by:

  • narrowing it down to one specific file where there is coverage reported in your Cobertura report but not in SonarCloud
  • check if there are files represented in your Cobertura report (where coverage is being reported) that don’t show up in SonarCloud
  • check if there are files showing up in SonarCloud (with no coverage reported) that aren’t in your Cobertura report

Thank you very much for the response. Your suggestions were spot-on. As it turns out, these were integration tests, not unit tests. As such, the logic was only consuming the interfaces, not the implementation, so it’d make sense that a lot of the files didn’t appear to be touched.
