 ## Top-level functions
 
-Kotlin lets you write functions that don't belong to any class or object, called [top-level functions](https://kotlinlang.org/docs/reference/functions.html#function-scope). These calls are translated to static methods in Java, and a special Java class is generated to hold the functions. These top-level functions can be mocked using [`mockkStatic`](./static.md), but you need to figure out the class name of this generated Java class.

+mockkStatic(::toplevelFunction)
