Coverage not analyzing less than 20 lines on new lines

Hello community,

I see a comment on SonarCloud that basically says that less 20 lines are not going to be analyzed for New Lines.

I see this ticket open, but not sure if this is only for SonarQube

Problem when PR has less than 20 new LOCs

Hi teams, I am using Sonarcloud to ensure my company code. I use default quality gate with 80% code coverage need to be done. Then i get caught of this problem which really miss our expectations of the analysis: When we create a new PR with 16 new lines of code, sonarcloud said that the number of new LOC is too small so they do not scan as “Some Quality Gate conditions on New Code were ignored because of the small number of New Lines” However, when we merge the PR into master, the analysis fo…

I also saw an older very similar ticket - Problem when PR has less than 20 new LOCs

Can someone let me know if there’s a feature enabled for SonarCloud?

Hi,

It’s not that fewer than 20 lines aren’t analyzed. It’s that Quality Gate conditions on Coverage on New Code and Duplications on New Code aren’t enforced when there are fewer than 20 new lines.

A toggle to turn off this behavior has been added to SonarQube, but not in SonarCloud.

 
HTH,

Thank you Ann for the reply!

Is there any plan for a feature to block this in SonarCloud?

Thanks again

Hi,

Sorry, but I’m not currently aware of any plan for that.

Hi Ann, if there are no plans to add a user setting for minimum number of lines changed to affect a quality gate, it would be very much appreciated if you could at least display a notification in the summary page explaining why the quality gate passed regarding this issue. Currently sonarcloud does not explain this in the summary nor in the detailed measures reports. Thanks!

Thank You for pointing this out, Sean.
We will look into this opportunity for improvement.

Hi,

Could you please tell me where is that toggle button and in which minimum version it is? I can’t find it on SonarQube.

Hi Ludo,

It’s in Administration, under General. I know you’ll find it in 10.5.1.

Thanks for you answer, I’m in version 9.9.1 and I can see a tooltip saying
"
At the start of a new code period, if very few lines have been added or modified, it might be difficult to reach the desired level of code coverage or duplications. To prevent Quality Gate failure when there’s little that can be done about it, Quality Gate conditions about duplications in new code and coverage on new code are ignored until the number of new lines is at least 20. An administrator can disable this in the general settings.
".
So I guess it’s also available in version 9, but can’t find it in general settings.

Hi,

Do you have access to Administration? If so, search in the browser for the word ‘small’

Spot on! Thank you very much indeed.

Hello,
Is it possible to update for 10, or 5 instead the default 20 ?

[ganncamp (G Ann Campbell)]

Hi,

To be clear, since this thread is filed under SonarCloud: no configuration is available for this in SonarCloud.

In SonarQube you can choose to turn it off or leave it on. That’s all.

And since this is an old thread, I’m going to close it now to prevent its being resurrected yet again.
