Sorry for me lacking deep motivation to learn Gradle at the moment

I have JUnit5 working
Please help me with `build.gradle.kts` for *property testing* with Kotest

I'd prefer to try it in parallel (not technically said)
      with another recommended for Kotlin/JVM engine (jqwik? or any preferred over it)
And I'm still having no sense of kotlin.test

I would avoid the kotest gradle plugin as that is experimental, and use the kotest/junit integration which you have added via the kotest-framework-engine-jvm dependeny.

There is an official word in the docs that seems claiming the opposite

"This is an alternative to using JUnit5 support and provides better output than the gradle default, especially for nested tests."
<https://github.com/kotest/kotest-gradle-plugin>

BTW, I need a kind of multitest build as a learning device, to get some fluency refactoring tests (between test frameworks) and to select the best framework up to my needs

If I disable the kotest-framework-engine-jvm dependency there is no more FunSpec еtс.

What to be added instead?

Sorry I'm getting opposite advice right now, but still have no understanding how to manage builds, these ones that include kotest

Do you want a sample build that has kotest in it
