How can I write tests for a kts script?

The scripts are compiled into regular kotlin classes, so you can create an instance of it to evaluate. There are some tests for scripts in the kotlin project, e.g. https://github.com/JetBrains/kotlin/blob/master/libraries/tools/kotlin-main-kts-test/test/org/jetbrains/kotlin/mainKts/test/mainKtsTest.kt

lol, took me months to see this. Thanks!
