A modern programming language that makes developers happier.

What is the current state of  `Kotlin` + `Jacoco`?  Can I use `Jacoco` to get `JUnit` test coverage of Kotlin code? Does some one uses is on day to day basics?  How mature is it currently with Kotlin?

You can use it, but the reports aren’t very accurate, from my observations — IJ’s coverage is vastly different from Jacoco’s

Things seem to be improving with new Jacoco versions, though

This would explain why I haven’t seen many articles on this subject. Do more people agree with this ?

Just to be clear, _not very accurate_ doesn’t mean the metric is worthless — I’m using Jacoco and don’t plan turning it off. But I wouldn’t e.g. set coverage targets

As for articles — it may be due to the fact that there’s nothing different in configuring Jacoco with Java vs Kotlin :slightly_smiling_face:

I use it and the only problem I had so far is that Jacoco can't detect code coverage of inline functions.

:point_up: Same here

Supposedly, this is fixed in AGP 3.4, but we are currently on 3.2.1 and bumping requires herculean effort.
