how do i configure kotest to run without junit in gradle and idea? what dependencies do I use?

You need junit for gradle

oh i thought there was experimental support for gradle without junit

Yes, there is experimental support. If you'd like to try it and feed back you can, but it's JVM only (as JUnit support is). https://github.com/kotest/kotest-gradle-plugin

junit support is also jvm only? how do i run kotest tests on js for example?

yes, for JS it builds on top of the compiler support that kotlin.test also uses. So JS -> use kotest engine Intellij - use kotest engine JVM - use junit (which will add engine transitively) or the gradle plugin (use engine)

ok so its a long way? does it still have bugs?

I think its ok, but until more people test it, it won't be considered robust
