Is it possible to use Mockito in Kotlin?

by

There are two possible workarounds:

private fun <T> anyObject(): T {
    Mockito.anyObject<T>()
    return uninitialized()
}

private fun <T> uninitialized(): T = null as T

@Test
fun myTest() {
    `when`(mockedBackend).login(anyObject())).thenAnswer { ... }
}

The other workaround is 

private fun <T> anyObject(): T {
    return Mockito.anyObject<T>()
}

@Test
fun myTest() {
    `when`(mockedBackend).login(anyObject())).thenAnswer { ... }
}

Here is some more discussion on this topic, where the workaround is first suggested.
