URGENT: jacoco and intellij IDEA15 code coverage results are different for same Junit tests.

[anwa...@gmail.com]

Hi folks,

we are getting a wired issues could you please show some pointers

we are getting jacoco and injellij IDEA 15 Junit code coverage reports differently any pointers would be greatly appreaciated

[Marc Hoffmann]

What exactly means "differently"? What exactly are you comparing?

Note that only JaCoCo has 6 different coverage metrics:

To identify differences it is typically helpful to drill down to a
specific class/method and compare result.

Hi Marc,

Reports generated from Jenkins jacoco reports are different than generated with local intelliJ idea

Are there any specific reason for this? How can we get this sorted? Any live examples of partial coverage on IntelliJ w.r.t Jenkins jacoco am using jacoco plugin 1.0.19 on Jenkins where as 0.7.5 on local IntelliJ

Please help will be really appreciated

Hi Anwar,

I believe that Jenkins plugin is dealing with data produced by JaCoCo that is declared in yours build scripts.

IntelliJ bundles particular version of JaCoCo, which is BTW 0.7.2 and not 0.7.5 as you claim - proof: https://github.com/JetBrains/intellij-community/tree/master/plugins/coverage/lib

What to do to use same version in both cases? Obviously there is no options other than: either downgrade first, either upgrade second. I wouldn't recommend first one, because later versions are better, i.e. data in Jenkins should be better / more precise, but as stated earlier - watch your build scripts. For the second one - ask JetBrains developers that maintain this integration. Unfortunately there is nothing with which we can help you here - all this is not owned by us.

My personal opinion: what matters for code quality - is a focus on addition of missing tests for changed/added parts of code instead of focus on absolute value and match of values between tools. As long as usage of both of tools allows you to achieve this, it is acceptable to use different tools (even non-JaCoCo mode in IntelliJ) and have slight mismatch.

P.S. Please respect the fact that help here is provided to you for free by other people in their spare time on a best effort basis, i.e. be ready that when you start thread with word "urgent" - it will not get a quick answer purposely or even will be ignored. Especially that you are allowing yourself to not respond within months. Thank you for your understanding.

Regards,

Evgeny
