Trying to test the server (runs on a different host and port) via the Kotlin Test library, and have encountered a situation where when running a test it runs indefinitely. Below is the test logic:
Copy code
import io.kotlintest.specs.FunSpec
import io.ktor.application.Application
import io.ktor.http.HttpMethod
import io.ktor.http.HttpStatusCode
import io.ktor.server.testing.handleRequest
import io.ktor.server.testing.withTestApplication
import kotlin.test.assertEquals

class RouteTest : FunSpec() {
    init {
        testHomeRouteExists()
    }

    private fun testHomeRouteExists() = test("homeRouteExists") {
        withTestApplication(Application::main) {
            with(handleRequest(HttpMethod.Get, "/")) {
                assertEquals(expected = HttpStatusCode.OK, actual = response.status())
                assertEquals(expected = "Battery Info Server\n", actual = response.content)
            }
        }
    }
}
Resolved the issue by restructuring server.kt file to the following:
Copy code
// ...
fun main() {
    val env = applicationEngineEnvironment {
        module { main() }
        connector {
            host = GeneralSettings.host
            port = GeneralSettings.port
        }
    }
    <http://logger.info|logger.info>("Starting server (on http://${GeneralSettings.host}:${GeneralSettings.port})...")
    embeddedServer(factory = Netty, environment = env).start(true)
}

fun Application.main() {
    connectToDb()
    install(ContentNegotiation, setupJackson())
    install(StatusPages, setupStatusPages())
    routing {
        homeRoute(this)
        ownerExistsRoute(this)
        listOwnersRoute(this)
        setupSiteRoutes(this)
        setupSensorDataRoutes(this)
        sensorDataTimestampRangeRoute(this)
    }
}
// ...

I had a similar problem when using two connectors for two different ports... which piece solved the problem exactly? Would it apply for two ports too?

Before the restructuring there was no main module (Application::main) which was the missing piece to get testing in Ktor to work.
Since then I have created a separate testMain module that is used in tests which looks like the following:
Copy code
fun Application.testMain() {
    install(ContentNegotiation, setupJackson())
    install(StatusPages, setupStatusPages())
    routing {
        homeRoute(this)
        setupOwnerRoutes(this, true)
        setupSiteRoutes(this, true)
        setupSensorDataRoutes(this, true)
    }
}
The connector is only applicable to the Production server. Ktor takes care of configuring the Test server. There is no need to provide a host and port.

Oh... I used the new
port(8080) { ... }
route, and the tests seem to ignore it, I guess its a different problem then 😞
