is there a way to use jest as test runner instead of karma as descriped here https://kotlinlang.org/docs/reference/js-project-setup.html#configuring-test-task?

what i’m trying to archive is to have unit tests that don’t start a browser (unlike the karma tests) and testing my react components with enzyme.

is an example regarding react with enyme available somewhere? or are their other hints how to archive testing that you are just to when comming from typescript (like react testing with jest and enyme)

Enzyme can work with mocha and karma that is supported by our Kotlin/JS Gradle plugin. Example: https://github.com/snrostov/kotlin-full-stack-application-demo/blob/snrostov/kotlin-1.3.40/client/src/test/kotlin/EnzymeTest.kt

https://github.com/snrostov/kotlin-full-stack-application-demo/blob/snrostov/kotlin-1.3.40/client/build.gradle#L53-L54

Is you want tests without brwoser, you can configure enzyme with mocha: https://airbnb.io/enzyme/docs/guides/mocha.html

Mocha is used in Gradle Kotlin/JS plugin to running tests in NodeJS, so you should write nodejs { }
instead of browser . Does it work for you?

Thx for response, I'll give it a try when I'm back home from the kotlin conf :)
