Is there an example of kotest framework mpp setup somewhere?

I have that exact setup yet I'm getting
```Caused by: org.junit.platform.commons.PreconditionViolationException: Cannot create Launcher without at least one TestEngine; consider adding an engine implementation JAR to the classpath```

Can you try adding the engine-jvm dependency to your jvm deps and the engine-js to the js one? I noticed this on my project last week and thought it was something I had done. If that works for you we can track down what's going on

is engine dep in commonTest not sufficient?

I thought it was but perhaps it's not, I'll be on my work computer in 30 to check my project

Do I still need junit5 runner for jvmTest too?

What gradle plugin and lib versions do you use?

:thinking_face: ok I'll check in a bit, I'm using 5. M2

I'm on io.kotest.multiplatform:5.0.0.5 &amp; lib:5.0.0.M3

Nvm, figured it out. There was race condition in my gradle scripts. Everything works now.

Well not everything, nested testing in js is still not supported, unfortunatelly

Ah cool, do you not need the specific engines listed?

nested testing will never work on JS unfortunately, as the outer scopes in karma/mocha don't support async

I see, thanks for clarifying. Would be good to have some table in the docs outlining what does and doesn't work on js, tho.
