Add helper function somewhere in your test package:

```auto
inline fun <reified T: Any> mock() = Mockito.mock(T::class.java)

```

and use it instead of Mockito’s:

```auto
val view: View<MyModel> = mock()

```

You can also use the following library which adds this and few other functions to better suit Mockito for Kotlin: [GitHub - mockito/mockito-kotlin: Using Mockito with Kotlin](https://github.com/nhaarman/mockito-kotlin/)
