Getting started

Apply the Gradle plugin and activate the helper dependency:

plugins {
    kotlin("multiplatform")
    id("org.kodein.mock.mockmp") version "1.17.0"
}

kotlin {
    // Your Koltin/Multiplatform configuration
}

mockmp {
    usesHelper = true
    installWorkaround()
}

Create a test class that declares injected mocks and fakes:

class MyTest : TestsWithMocks() {
    override fun setUpMocks() = injectMocks(mocker) (1)

    @Mock lateinit var view: View
    @Fake lateinit var model: Model

    val controller by withMocks { Controller(view = view, firstModel = model) }

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

This is mandatory and cannot be generated. You need to run the KSP generation at least once for your IDE to see the injectMocks generated function.

Every property annotated by @Mock, annotated by @Fake or delegated to withMocks will be reset fresh between each test.
