Kover sets Instructions coverage to >0%, but class is not called

[caleyass]

Hello, I have a question. Why I have classes, that are not called in my tests, but Kover shows that instructions coverage is >0%?

Hi,
It really looks strange.
However, we have stopped supporting our IntelliJ agent, so if you have the option, you'd better switch to using JaCoCo.

As part of the Kover plugin, this can be done by specifying next configuration in each module where Kover is applied:

kover {
    useJacoco()
}

thnx , it solved problem, but now I have problem, that after I added Jacoco agent , coverage plugin stopped measuring code in view model scope - with IntelliJ agent it worked. I use in test advanceUntilIdle and they pass, but in coverage report it is not seen

Try using the latest version of JaCoCo

kover {
    useJacoco("0.8.13")
}

no, it still does not highlight viewModelScope

I solved it. Jacoco agent does not add automatically byte code classes for coroutines - as Intelij agent did, that's why you need to add manually to report coroutines classes with filter "*ViewModel*" instead of "*ViewModel" (that I had). Btw, why you stopped supporting IntelliJ agent?

The IntelliJ agent and JaCoCo are almost equal in their capabilities, in some features JaCoCo is even ahead.
We decided that it would be the best solution to help improve an existing product (JaCoCo), and the freed up resources can be used to improve the UX for Kotlin users - namely, creating a Kotlin-specific report.

Could you please describe in more detail what changes you have made? It might help other users who encounter a similar issue.
