Hey all, quick question as I can't find any solid resources for this. How does one test extension methods? Say I have something like

fun Date.isWeekend() = day == 6 || day == 7

Inside a class. How do I go about unit testing this?

Should be straightforward if you are writing Kotlin Test classes but if you are using Java you can add @JvmName("isWeekend") annotation to the method and then call it by passing the Date as the 1st parameter: e.g.

isWeekend( new Date())

(forgotten how much I hate writting

new

🙂 )

The JvmName is already

isWeekend

. You shouldn’t need an extra annotation
