Also, in this sample: https://github.com/h0tk3y/k-new-mpp-samples/tree/master/lib-with-tests

./gradlew jsTest

doesn't actually run any tests for JS. It looks like it spits out a file into

build/classes/kotlin/js/test/lib-with-tests_test.js

, but the report in

build/reports/tests/jsTest/index.html

says 0 tests run. Is there a working sample with the new MPP plugin where the JS tests are set up to actually run?

Thank you for the notice. You may find the sample here: https://github.com/Kotlin/kotlinx.atomicfu/blob/nmpp/atomicfu/build.gradle And here is a boilerplate for the run: https://github.com/Kotlin/kotlinx.atomicfu/blob/nmpp/gradle/test-mocha-js.gradle
