Code coverage is always lower in pipeline

[katmandu25]

Hi all.

When I execute the pipeline to deploy my software to DEV and the code scanning step finishes, the porcentage of code coverage is much lower is the pipeline than in my local IDE.

Can anyone explain me where is the difference or what am i missing?

  

I have attached two snapshots, one from pipeline and another from my IDE. Thanks in advance.

Hi @katmandu25 
Could you please download the build logs and check the code coverage?

Hi Arun.

I have seen the code scanning step log and is full of message of this type

org.sonar.java.se.ExplodedGraphWalker$MaximumStepsReachedException: reached limit of 16000 steps for method init#88 in class OffersAPIModel

But I don´t think so it was the problem. I haven´t seen anything important in this log

Thanks in advance.

Your IDE will generally only calculate the line coverage but cloud manager also takes into account the conditional coverage to calculate the final value which is generally the reason for difference. 
Formula which they use :

Coverage = (CT + CF + LC)/(2*B + EL)

• CT = Conditions that have been evaluated as true at least once while running unit tests
• CF = Conditions that have been evaluated as false at least once while running unit tests
• LC = Covered lines = lines_to_cover - uncovered_lines
• B = total number of conditions
• EL = total number of executable lines (lines_to_cover)

Formula Copied from below link

If you have jacoco configured in your project then you will get better reports when you run the build using maven.

Thanks for your reply.

I have configured my Intelliji for using Jacoco, but the numbers are the same, more than forty percent of diference between pipeline and my local IDE

[h_kataria]

Was there no difference at all when you used Jacoco with intelliJ. I personally don't use intellij but can you post what kind of reports are being generated when you use Jacoco ? Is it showing branch coverage ?

[EstebanBustamante]

Hi, 

Try to run Jacoco's report and see how much differs from the cloud, I think it is closer than what you could get in your IDE. 

Please check this thread: https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/check-junit-coverage-on-ae... 

Hope this helps
