What is the difference between `produceExecutable()` and `produceKotlinLibrary()` in Kotlin 1.4-M1 Gradle DSL?

from <https://blog.jetbrains.com/kotlin/2020/03/kotlin-1-4-m1-released/> – but let me know if things are unclear about this description :slightly_smiling_face:

`produceKotlinLibrary()` just makes the absence of `produceExecutable()` explicit, but it’s the default behavior.

If I use the default (no executable js) will I be able to run any tests e.g. with Karma?

No, you need to generate “real” JavaScript code in order to execute it.

So no more tests for Kotlin Libs :stuck_out_tongue:

Is there any mode which produces Kotlin Lib, but also enables platform-specific testing?
I think it’s how it eventually should work for MPP libs, you always produce Kotlin Lib as final artifact, but run test to all target platfroms

<@UFT11FKSP> – sorry for digging up this old thread. But the behavior you mentioned is _actually_ how `binaries.executable()` behaves. You will still be able to run your Karma tests. The test task will generate actual executable JS code. Makes a lot more sense that way, you were right. Looks like I took some of our internal documents too literally :wink:
