Hey folks,
I’m getting started with koin and ktor and have some difficulties with the initial setup as I practically can’t make it working with tests to inject different implementation there.

fun Application.webModule(koinModules: List<org.koin.core.module.Module> = listOf(applicationModule)) {

    install(Koin) {
        printLogger(level = <http://Level.INFO|Level.INFO>)
        modules(koinModules)
    }
    val tracksController: TracksControllerInterface by inject()

    configureRouting(tracksController)
}

In the tests I create the mock that I inject

private val tracksController = mockk<TracksController>()

    private val testModule = module {
        single<TracksControllerInterface> { tracksController }
    }

    @Test
    fun `GET tracks returns list of available tracks`() = testApplication {
        application {
            stopKoin()
            webModule(koinModules = listOf(testModule))
        }

But I keep getting issue that Koin plugin was already installed

Please make sure that you use unique name for the plugin and don't install it twice. Conflicting application plugin is already installed with the same key as `Koin`

I understand that testApplication actually does that, but not sure what is the best way to hook into it and make it working. Many thanks for suggestions, links or articles.
