Static analysis is only one way of ensuring your code quality. Another way of ensuring it is by creating an extensive test suite for your project. But many of you know about one problem with testing in Kotlin that existed since the first release. It’s been a challenge to measure the code coverage precisely. There are some great tools like JaCoCo that work with Kotlin code, but they are not integrated well with our Gradle toolchain and multiplatform projects. In this Kotlin release we’re starting to fix this issue.
In this video, we present you Kover - our new Gradle plugin that measures code coverage for Kotlin code built with Kotlin/JVM compiler. We'll go over its main features and explain how to set it up in your project, so you won't have problems with coverage any more.

Looks great! Looking forward to trying this, it looks like it resolves a lot of the issues we had with plain Jacoco
Looks very promising. I have waited for this! :)
Very interesting. Looking forward to compare plain Jacoco with new plugin.
Great! Looking forward to it. Unfortunately I cannot use it in the real project because it seems to lack some basic features like excluding specific classes and separate methods granularly (like Jacoco does by using the "@Generated" annotation), which is essential to filter out false "uncovered" code in generated/boiler code methods. But I hope Kover will catch up and become the primary coverage tool.
I’m eager to try it!

Already running in our KMM project at work 🙂
Since I have enabled the plugin, about 10% of my tests were failed, when I started "test with Coverage"
Does Kover handle the hidden kotlin null checks conditional branches? This is why it's impossible to get to 100% with jacoco.

It should handle them, yes.
Looks interesting, is this compatible with android projects?

Yes, recently released version supports them
And what about maven? Out of luck?

good catch! I did not see this. But why would one use MVN now days. Gradle is so much faster.
Man, this is _not_ ready for Android development yet. Well, I did my due diligence and created 3 issues about this: #76, #77 and #78. - edit: well that's fast. 2 of these are actually already fixed and it's now actually usable now.

Still not fitting well for complex android projects (multiple modules with multiple flavors.)
Maybe have a glass of water handy next time! He seems thirsty!
