hello! it appears that it is not possible to capture arguments to mocked methods based on the other arguments - is that expected? e.g.

class MockkCaptorTest {

    @Test
    fun `verify mockk captor behavior`() {
        val simpleMockk = mockk<Simple> {
            every { hello(any(), any()) } answers { "Mocked response for ${arg<String>(0)}, age: ${arg<Int>(1)}" }
        }

        simpleMockk.hello("Bob", 2)
        simpleMockk.hello("Alice", 1)

        val bobsAge = slot<Int>()
        verify {
            simpleMockk.hello("Bob", capture(bobsAge))
        }
        assertEquals(2, bobsAge.captured)
    }
}

class Simple {
    fun hello(name: String, age: Int) = "Hello $name, age: $age"
}

above will actually capture Alice age

note: mockito handles this fine

i'm not sure you're using capture slots correctly

[Dariusz Kuc]

me neither, thats why I'm asking

[LeoColman]

I think the capture should happen on the every block

[LeoColman]

and then you'll use the slot for verifications

[LeoColman]

However I'm not sure how you can link those parameters

[Dariusz Kuc]

well i can pass a mutable list for capturing slots that will capture all of the args but again my problem is that I would have to explicitly capture all of the params

[Dariusz Kuc]

and then iterate over the first one to find out the index of the one i'm interested in

[Dariusz Kuc]

if thats the only option then it is an oversight
