SonarCloud failing to display coverage metrics despite successful parsing

[TheRSP (Richard)]

We’re using Azure DevOps to publish C# code coverage to SonarCloud. This has been working brilliantly across most of our solutions. However, we’re trying to set up a new solution at the moment and can’t get SonarCloud to show coverage data.
We are producing coverage data using Coverlet and formatted as opencover reports which seem correct.

I can see that the analyzer is parsing the coverage files but it doesn’t seem to display anything in the quality gate.

Is there any way to find out what is happening to this coverage data after being parsed? Where is it being dropped/why?

Hello @TheRSP,

Apologies for the delayed reply. Are you still experiencing the problem? If so, I will ask privately for organization details, so I can investigate more.

Best,
Marcim

Hi @Marcin_Majewski , thanks for getting back to me. Yes, we are still facing this problem

Hey there. Are you still facing the issue? I wonder if it’s not the same as this issue which was fixed this week.

PR analysis does not report coverage and says that coverage needs to be setup when I only added unit tests in the PR

Hey @StingyJack Thanks for reporting this. I can reproduce this on a project where I’ve introduced new lines, but those lines can’t be covered by tests. It’s… confusing, to say the least. I’ll report this internally.
