In their own words
Kover
Kover is a free, Apache-2.0-licensed toolkit maintained by Kotlin for measuring test coverage in Kotlin and Java code compiled for JVM and Android targets. It provides Gradle and Maven plugins, a command-line interface, offline instrumentation, a JVM agent, and a features artifact. The Gradle plugin creates HTML and XML reports, supports IC output, and can enforce coverage gates using line, instruction, and branch measurements. It integrates with Kotlin JVM, Kotlin Android, Kotlin Multiplatform, and the com.android.kotlin.multiplatform.library plugins, including mixed Kotlin and Java sources. JaCoCo can replace Kover for measurement and report generation. Android build variants and Android host tests are supported, but instrumented tests on devices are not collected. JavaScript and native targets are outside the Gradle plugin’s support. Requirements include Gradle 6.8.3 or later, JVM 1.7 or later for tests, and Android Gradle Plugin 7.0.0 or later. Class instrumentation during JVM test loading may affect performance or concurrent tests.
