For one of our Ruby projects, we split its test suite into several chunks, run them in parallel, and feed SonarQube with all partial code coverage reports. That, however, results in SonarQube incorrectly reporting non-executable lines of code (empty, ends, etc.) as not covered. This is caused by So…

Hey there. What version of SonarQube are you using?

Hey @Colin ! We’re using SonarQube 10.4.1.

You’re right, that’s the same issue. I’m sorry for reposting it. As I dug into that issue, I believe I’ve got a fix for it that I can contribute, but I’d like someone to confirm if that’s ok and if so, create a ticket for that.

@Colin are there any updates for this request? Just to clarify: I don’t expect dev team to fix the issue, I already have a change that should hopefully fix it, all I expect is some preliminary assessment and a Jira ticket I could propose my fix under.

Hey @GreyTeardrop I’ve just pinged the relevant dev team (who would be responsible for creating a ticket and reviewing any PR). Sorry if it got lost. You’re welcome to raise a PR anytime at GitHub - SonarSource/slang , even if there’s not a ticket yet.

Thank you! I’ve opened Fix merge logic for Ruby SimpleCov coverage reports by GreyTeardrop · Pull Request #333 · SonarSource/slang · GitHub .

Great. I’ve linked back to your community threads just in case our devs see your PR first before they see my ping :slight_smile:

Hey @GreyTeardrop , Thank you for your report and for following through with a detailed investigation of the issue. Following your discussion with @Colin , I have created a ticket to track the issue.

Hello! Were these changes/fixes ever deployed to SonarCloud? I am also experiencing discrepancies between my Rails project, RSpec/SimpleCov (97-98%) and SonarCloud (89-90%) many months later.
