mill.kotlinlib.kover

Allows the aggregation of coverage reports across multi-module projects.

Once tests have been run across all modules, this collects reports from all modules that extend KoverModule.

• ./mill __.test # run tests for all modules
• ./mill mill.kotlinlib.kover.Kover/htmlReportAll # generates report in html format for all modules
• ./mill mill.kotlinlib.kover.Kover/xmlReportAll # generates report in xml format for all modules

The aggregated report will be available at either out/mill/kotlinlib/contrib/kover/Kover/htmlReportAll.dest/ for html reports or out/mill/kotlinlib/contrib/kover/Kover/xmlReportAll.dest/ for xml reports.

Adds targets to a mill.kotlinlib.KotlinModule to create test coverage reports.

This module allows you to generate code coverage reports for Kotlin projects with Kover.

To declare a module for which you want to generate coverage reports you can mix the KoverModule trait when defining your module. Additionally, you must define a submodule that extends the KoverTests trait that belongs to your instance of KoverModule.

import mill.kotlinlib.KotlinModule
import mill.kotlinlib.kover.KoverModule

object foo extends KotlinModule with KoverModule {
 def kotlinVersion = "2.0.20"

 object test extends KotlinTests with KoverTests
}

In addition to the normal tasks available to your Kotlin module, Kover Module introduce a few new tasks and changes the behavior of an existing one.

• ./mill foo.test # tests your project and collects metrics on code coverage
• ./mill foo.kover.htmlReport # uses the metrics collected by a previous test run to generate a coverage report in html format
• ./mill foo.kover.xmlReport # uses the metrics collected by a previous test run to generate a coverage report in xml format

The measurement data by default is available at out/foo/kover/koverDataDir.dest/, the html report is saved in out/foo/kover/htmlReport.dest/, and the xml report is saved in out/foo/kover/xmlReport.dest/.
