Kotlin: Access private var in test

I have a Kotlin class containing the following property

private var items: List<Item> = listOf()

In my test I now want to check if there are items in the list. I try to do this with reflection:

val field = sut::class.members.findLast { f -> f.name.equals("items") }

I now get a KCallable<*> back but I don't know how I can access or at least count the items in my list.

The KCallable you get is actually an instance of KProperty1, and you can call its get method to get the instance:

 val items = (field as KProperty1<ClassUnderTest, List<Item>>).get(sut)
