Mockito-Kotlin is a wrapper library around Mockito.

It provides top-level functions to allow for a more idiomatic approach while using Mockito in Kotlin. Furthermore, Mockito returns null values for calls to method like any(), which can cause IllegalStateException when passing them to non-nullable parameters. This library solves that issue by trying to create actual instances to return.

Mockito-Kotlin does not intend to alter any of the functionality that Mockito provides, except in places where crucial for working with Kotlin.
