Warnings during JVM tests

Nice! Perhaps, we could make ignored classes abstract and add a factory function with the same name?

fun SingleToSingleTests(...): SingleToSingleTests =
    object : SingleToSingleTestsImpl(...) {}

private abstract class SingleToSingleTestsImpl(...) {
...
}

Maybe even abstract wouldn't needed if the class is private.

The solution I described should work, though there is a new warning now in Kotlin 1.9.20, for every test method. Filed https://youtrack.jetbrains.com/issue/KT-63132.
