Verify Extension Function / kotlin

@RunWith(MockitoJUnitRunner::class)
internal class HighOrderTest {
    @Mock
    lateinit var a: A

    @Test
    fun test() {
        // When
        a.run()
        
       // Then
        verify(a).doSomething()
    }

}

open class A

fun A.run() {
    doSomething()
}

fun A.doSomething() {

}

The above test will fail with:

org.mockito.exceptions.misusing.UnfinishedVerificationException: 
Missing method call for verify(mock) here:

I guess it’s not possible yet to verify the high order doSomething. Is it possible to implement this feature? If not a explicit error would be helpful I think

those are extension functions dudes, not high-order functions.

[wengelef]

anyway, this works for me.

class A

fun A.foo(): String {
    return bar()
}

fun A.bar(): String {
    return "test"
}

init {
    val a = mock<A>()

    "when extension A.foo Function is called, it should return '\"test\"" {
        a.foo() shouldBe "test"
        verify(a, times(1)).foo()
        verify(a, times(1)).bar()
    }
}

are you using mockito-kotlin?
