Is there any way to configure karma daemon "interactive" tests in the browser with the new Kotlin/JS plugin (like it was with the old kotlin-frontend-plugin)?

[turansky]

Is it standard logic for karma?

[Robert Jaros]

No idea 🙂

Robert, can you show a small snippet of this "interactive" setup for kotlin-frontend-plugin - I'm not sure I understand what is tried to be achieved.

[Robert Jaros]

It was the default setup of kotlin-frontend-plugin. When executing run command karma daemon was started on http://localhost:9876/. It looked like this:

It was hot reloaded when the source code changed.

I'm just wondering if this can be achieved with new Kotlin/JS plugin.

This is how it was configured: https://github.com/Kotlin/kotlin-frontend-plugin#karma

Hi! It is not implemented yet in new plugin, but you can use such workaraound
You need to create karma.config.d/<any>.js with such content

config.singleRun = false

You can run two Gradle processes, the first
./gradlew compileTestKotlinJs *-t* it runs compilation in contionuous mode, and will react on changes of code.
The second one (in other terminal) you need to run ./gradlew browserTest
