kmockito

Mockito for Kotlin.

when is a reserved word of Kotlin. You should write like below on test.

val item = mock(Item::class.java)
`when`(item.length()).thenReturn(10)

hmm... OK. I'll add extensions for Kotlin.

mock

before

var item = mock(Item::class.java)
`when`(item.length()).thenReturn(10)

assertThat(item.length(), `is`(10))
verify(item).length()

after

var item: Item = mock()
item.length().invoked.thenReturn(10)

assertThat(item.length(), `is`(10))
item.verify().length()

I recommend that you also use knit. It is JUnit API for Kotlin.

spy

before

var item = spy(Item(10))
doReturn(11).`when`(item).length()

assertThat(item.length(), `is`(11))
verify(item, times(1)).length()

after

var item = Item(10).spy()
item.doReturn(11).length()

assertThat(item.length(), `is`(11))
item.verify(times(1)).length()

Answer

before

model.someMethod(anyInt(), anyString(), any(), any())
    .invoked
    .thenAnswer {
      val a = it.arguments[0] as Int
      val b = it.arguments[1] as String
      val c = it.arguments[2] as Item
      val d = it.arguments[3] as Name

      // do something
    }

after

model.someMethod(anyInt(), anyString(), any(), any())
    .invoked
    .thenAnswer {
      val (a, b, c, d) = it.arguments4<Int, String, Item, Name>()

      // do something
    }
