Is it possible to mock Mockito accessories in Kotlin?

Question

Is it possible to mock the recipient and installer of the Mockito property? Something like that:

@Test fun three() { val m = mock<Ddd>() { // on { getQq() }.doReturn("mocked!") } assertEquals("mocked!", m.qq) } open class Ddd { var qq : String = "start" set(value) { field = value + " by setter" } get() { return field + " by getter" } } 

Answer 1

To mock a recipient, simply write:

 val m = mock<Ddd>() `when`(m.qq).thenReturn("42") 

I also suggest using mockito-kotlin to use useful extensions and functions like whenever :

 val m = mock<Ddd>() whenever(m.qq).thenReturn("42") 

Answer 2

Complementing the IRus answer, you can also use the following syntax:

 val mockedObj = mock<SomeClass> { on { funA() } doReturn "valA" on { funB() } doReturn "valB" } 

or

 val mockedObj = mock<SomeClass> { on(it.funA()).thenReturn("valA") on(it.funB()).thenReturn("valB") }
