can someone explain why this test fails:

val context = describe("ktor") {
        it("routing works") {
            val server = TestApplicationEngine(environment = createTestEnvironment {
                module {
                    routing {
                        route("/x") {
                            route("/y") {
                                get {}
                            }

                        }
                    }

                }
            }) {}.apply { start() }

            expectThat(server.handleRequest(HttpMethod.Get, "/x/y").response.status()).isNotNull().get { isSuccess() }.isTrue()
        }
    }

I think you need to call call.respond()...

you are right, thanks. is that documented anywhere? i would expect to see a 203 result or an internal server error, but no 404
