I could use some help understanding why this module for a ktor client fails -

fun provideKtorClient() = HttpClient(OkHttp) {
    install(ContentNegotiation) {
        json()
    }
}

val ktorModule = module {
    single { provideKtorClient() }
}

A simple test fails with the error -

@Test
    fun checkKtorModule() {
        ktorModule.verify()
    }

org.koin.test.verify.MissingKoinDefinitionException: Missing type 'io.ktor.client.engine.HttpClientEngine' for class 'io.ktor.client.HttpClient' in definition '[Singleton:'io.ktor.client.HttpClient']'

here it depends what you have in provideKtorClient()

Ultimately there were two separate issues -

Starting the app in Android Studio required restarting the IDE - must have been a caching issue

Running the sample test was resolved by using extraTypes
