How do you Mockk a Kotlin top level function?

There is way to mockk a top level function:

mockkStatic("pkg.FileKt")
every { fun() } returns 5

You just need to know which file this function goes. Check in JAR or stack trace.

The following syntax has worked to me.

mockkStatic(::sayHello.javaMethod!!.declaringClass.kotlin)

I'm surprised there is nothing on the jvm-stdlib yet for this.

Edit: This overload has now been introduced officially: https://github.com/mockk/mockk/pull/518

mockkStatic(::sayHello)
