    The coverage file (.coveragexml) and the unit tests results (.trx file) are correctly discovered, but the it seems sonar is unable to determine the tests files (*.cs) absolute path.

  • Potential workaround

No workaround. I’ve tried 100 different setup to make it work (including using dotnet-coverage tool instead of VSTest), no success at all.

Hey there.

Comparing all the files indexed by the scanner, and the files referenced in your coverage report, you seem to be dealing with two distinct sets of files:

The indexed files are in the projects:

  • Idefac.ServiceWindows.Process
  • Idefac.ServiceWindows.Business
  • Idefac.ServiceWindows.Domain
  • Idefac.ServiceWindows
  • Facturation.ServiceWindows.Tests
  • Idefac.ServiceWindows.Console

While when parsing your coverage report, all the files referenced in the report (covered by tests) are in the projects:

  • Moq (/_/src/Moq/…)
  • Facturation.Common.Infrastucture
  • Facturation.Common.Domain

So from here, it looks like the tests you’re running (and the coverage report generated) doesn’t match what you’re actually building.

I don’t know any more about your project, but maybe that’s a good place for you to start investigating. Are you actually testing what you’re think you’re building (and vice-versa)?

Hello,

Thank you for your response.

However, at this point, I don’t see what I can modify within the process.
I have provided almost all the elements at my disposal : CI yaml, folders and project structure, logs excerpts, csproj file of the test project…

Could you first let me know if, with these elements, it seems properly configured to push the code coverage into Sonar considering this context : .NET Framework, Azure DevOps, VSTask@3, etc ?

Thanks.

The pipeline looks correct!

But if the coverage file being produced doesn’t contain coverage for any of the files you’re building, there’s not much we can suggest :confused: Any other tool reading coverage data would face the same issue.

This is a Community where folks try to help each other. It is not a service desk where you provide all the files, and somebody works tirelessly to get you the answer. I looked at what you provided and called out what stood out to me. It may require more investigation on your part!

I highly suggest you

  • go back to your build logs and make sure what you’re building is what you’re expecting to build, and that the tests you’re running match that.
  • Double check the coverage report being produced by your tests. Does it contain the files you expect?

Hello,

Could you at least enlighten us about this error message :

The file '[...].cs' doesn't have a deterministic build path and isn't indexed or doesn't have a supported language. We'll skip this cover entry. What does “Verify sonar.sources in .sonarqube\out\sonar-project.properties

Do you have any documentation to understand the meaning and how to resolve this issue ?
Is it because .net projects are located in subfolders ( “/src” and “/tests”) ?

Note that “Moq”, “Facturation.Common.Infrastucture”, “Facturation.Common.Domain” are NuGet packages. The only sources we have in this solution are starting with Idefac.ServiceWindows and Facturation.ServiceWindows.Tests.

Also, I’ve tried to generate the coverage report with AltCover, no success either.

6

I’ve tried :

  • coverlet ==> KO (report always empty can’t figure out why)
  • AltCover ==> KO but report is filled, except sonar is unable to parse it correctly ?

Check out these logs for example :

17:51:58.556 DEBUG: 'Facturation.ServiceWindows.Tests/Fonctions/Revision/RevisionMensuelTests.cs' generated metadata as test with charset 'UTF-8'
17:51:58.556 DEBUG: 'Facturation.ServiceWindows.Tests\Fonctions\Revision\RevisionMensuelTests.cs' indexed as test with language 'cs'

Then…

17:52:18.108 DEBUG: The file 'Facturation.ServiceWindows.Tests\Fonctions\Revision\RevisionMensuelTests.cs' does not have a deterministic build path and is either not indexed or does not have a supported language. Will skip this coverage entry. Verify sonar.sources in .sonarqube\out\sonar-project.properties.
17:52:18.109 DEBUG: CoveredFile created: (ID '1021', path 'Facturation.ServiceWindows.Tests\Fonctions\Revision\RevisionMensuelTests.cs', NO INDEXED PATH).

It does not make any sense…

7

After making some more tests, i’m now pretty sure this issue occurs when the source files are in subfolders.

Example :

  • \rootdir
    • \src
      • \ProjectExample1
        • \fileExample.cs
        • \ProjectExample1.csproj
      • \ProjectExample2
        • \fileExample.cs
        • \ProjectExample2.csproj
    • \tests
      • \ProjectTest
        • \fileExample.cs
        • \ProjectTest.csproj

Sonar is going to index the source files with the relative path from “rootdir”, so src\ProjectExample1\fileExample.cs or tests\ProjectTest\fileExample.cs.

But the coverage report refers to ProjectExample1\fileExample.cs or ProjectTest\fileExample.cs.

Similar to the structure in this doc : Project's initial analysis scope | SonarQube Cloud Documentation

I guess many other projects use this folder structure, is it not handled natively in Sonar ?

8

After many many tests, I finally managed to find what the issue was.

I had a file named Directory.Build.props at the root of my sources, with this content :

<Project>
  <PropertyGroup>
    <PathMap>$(MSBuildProjectDirectory)=$(MSBuildProjectName)</PathMap>
  </PropertyGroup>
</Project>

Deleted it and now the coverage report contains correct file paths !
