I have a MSBuild task that builds a .Net Framework solution and a VsTest (2019) task to run NUnit with code coverage enabled and I see no errors being reported by the build.
The log from the VsTest task includes this:
...

In the Run Code Analysis task I see this in the logs that seems to suggests the coverage report was imported into SonarCloud successfully as I presume the .coveragexml was found (or it would raise an error):
...

I also see in the build summary page the code coverage results file, but in the SonarCloud project I see 0.0% code coverage being reported.
Any advice of what I should check in order to find a resolution to this problem?
Not sure if this helps but this is the start of the log for Run Code Analysis:
SonarScanner for MSBuild 4.10
Using the .NET Framework version of the Scanner for MSBuild
Post-processing started.

10:34:55.424 Looking for TRX files in: c:\agent\_work\1\TestResults
10:34:55.424 No test results files found
10:34:55.518 Did not find any binary coverage files in the expected location.
10:34:55.518 Falling back on locating coverage files in the agent temp directory.
10:34:55.518 Searching for coverage files in c:\agent\_work\_temp
The coverage reports are in fact under c:\agent\_work\_temp\TestResults
OK, I think I was misled by the overall figure, but I can see I am getting the code covered when looking at the class file.
SonarCloud is counting it against the whole solution and is showing an overall coverage of 0.0% but in fact navigating to the class being tested it is showing a 13% coverage, while Azure DevOps\VsTest seems to be calculating it against the project and showing 6.3% coverage overall, i.e. not taking into account the code in the whole solution since other projects have no tests covering them.
That is still weird to me. For sure we noticed some differences between the % calculated between Azure DevOps and SonarCloud, but the fact that it’s showing 0% is strange.
Is the coverage shown in AzDo related to the same classes that you have on SonarCloud by chance ?
