  • I believe development is happening on various plugins/tools for this. Meanwhile check this: https://discuss.kotlinlang.org/t/gradle-code-coverage-report/390 – jitinsharma Nov 24 '17 at 09:58

The Jacoco plugin works fine for coverage of Kotlin code. Configure Jacoco the same as you would for Java.

    JaCoCo incorrectly marks some lines as "partially covered by tests". See https://stackoverflow.com/questions/45525279/how-to-avoid-partial-coverage-with-lateinit-fields-in-kotlin – Paulo Merson Nov 12 '18 at 15:36

You can use the new kotlinx-kover Gradle plugin compatible with JaCoCo and IntelliJ.

plugins {
     id("org.jetbrains.kotlinx.kover") version "0.5.0"
}

Once applied, the plugin can be used out of the box without additional configuration.

Watch its YouTube announcement video and also track its roadmap from this youtrack issue.
