Hello there! I have a question on how to test e2e (making rest calls) a ktor+kodein application. The test should be included in the application project. I can explain better with a comparison to spring boot since I'm migrating from it. In Spring Boot I can create a test annotated with `@SpringBootTest`, starting up my application with a real context (no mocks); then using a `TestRestTemplate` I can call my rest api exposed to `<http://localhost>:{springBootRandomPort}`. Does anybody know a similar smart way to test this scenario also for a  ktor + kodein app? Unfortunately I wasn't able to find any examples on official documentation.

Do they have to be actual REST calls? Ktor has a great `withTestApplication` function that spins up nearly your whole app, but doesn't actually listen on HTTP.

Yes, they have to be actual rest calls and my understanding is, as you said, that  `withTestApplication`  doesn't spin up the whole app, and my goal is to test the whole app listening on HTTP.
