Example

const val MODULE_HTTP_API = "httpApi"

val httpApi = DI.Module(MODULE_HTTP_API) {
    bind<SomeHttpServer>(tag = MODULE_HTTP_API) with singleton {
        SomeHttpServer(serverConfig())
    }

    on(Start) {
        val server: SomeHttpServer = direct.instance(tag = MODULE_HTTP_API)

        server.start()
    }

    on(Stop) {
        val server: SomeHttpServer = direct.instance(tag = MODULE_HTTP_API)

        server.stop()
    }
}

val MyApplication = kodeinApplication {
    import(httpApi, allowOverride = true)
}

fun main() {
    MyApplication.run()

    // Remember to gracefully finish logging threads and flush buffers
    // Depends on your logging provider
    closeLoggers()
}

Testing

const val MODULE_TEST = "test"

val testConfiguration = DI.Module(MODULE_TEST) {
    bind<SomeHttpServer>(tag = MODULE_HTTP_API, overrides = true) with singleton {
        TestHttpServer(serverConfig())
    }
}

@Suppress("TestFunctionName")
fun TestApplication(extraConfig: DI.MainBuilder.() -> Unit = {}) = Kodein {
    extend(MyApplication, copy = Copy.All)
    import(testConfiguration, allowOverride = true)

    extraConfig()
}

internal class DeployControllerTest : DIAware {

    override val kodein = TestApplication() {
        // you can further configure it here with your test specific bindings and overrides
    }

    private val server: SomeHttpServer by instance(tag = MODULE_HTTP_API)

    @BeforeAll
    fun start() {
        server.start()
    }

    @AfterAll
    fun stop() {
        server.stop()
    }

    @Test
    fun someTest() = with(server) {
        // some test
    }
}
