Hey guys.
Funny enough, I also want to announce a new Kotlin/Multiplatform mocking library: Micro-Mock.
It uses KSP to generate mocks, and more or less replicates “classic” mocking systems.
Here’s a sample:

class MyTest {
    @set:Mock lateinit var view: View
    @set:Fake lateinit var model: Model
    lateinit var controller: Controller

    val mocker = Mocker()
    @BeforeTest fun setUp() {
        mocker.reset()
        injectMocks(mocker)
        controller = Controller(view = view, firstModel = model)
    }

    @Test fun controllerTest() {
        mocker.on { view.render(isAny()) } returns true
        controller.start()
        mocker.verify { view.render(model) }
    }
}

The following limitations apply:
• Mocking only applies to interfaces
• Faking only applies to concrete trees
The processor generates:
• Mocks of interfaces, allowing to mock behaviour & verify calls.
• Fakes of data classes, filling them of nulls, zeros, empty strings, and alike.
• Injector for test classes.
You’ll find it here : https://github.com/Kodein-Framework/Micro-Mock

We are using this in some of our own Multiplatform tests.
I hope it will be useful to the community 😉

Hah, I was thinking of writing something just like that recently to unblock MPP mocking 😄 Good job guys, saved me shitloads of time!
