How to really test the backend and avoid the use of MockWS? - scala

Question

I am fairly new to Playframework (and Scala in general). At the moment I am writing specs2 unit test that test python backend service, using MockWS. Yes, I found it great to test whether my frontend works using the same output as what the backend generated. But what if I really want to test the backend? How can I avoid the use of MockWS?
"SomeService" should {
object Props {
object Urls {
val BaseUrl = "http://localhost:9002/someservice/"
val Test = s"${BaseUrl}test"
}
val test = Test(value=true)
}
class NormalContext extends Scope {
val ws = MockWS {
case (GET, Props.Urls.Test) => Action {
Ok(Json.toJson(Props.test))
}
}
val abtestService = new SomeService(ws, Props.Urls.BaseUrl, 100)
}
"test mock" should {
"return True" when {
"call without any argument" in new NormalContext {
val result = someService.getTest()
whenReady(result) { result =>
result must equal (true)
}
}
}
}
}
I try to introduce this new context, but got the exception: java.lang.RuntimeException: There is no started application
Any suggestion?
class LiveBackEndContext extends Scope {
import play.api.Play.current
val ws: WSClient = WS.client
val abtestService = new AbTestService(ws, Props.Urls.BaseUrl, 100)
}
"test without mock" should {
"return True" when {
"call without any argument" in new LiveBackEndContext {
val result = abtestService.getTest()
whenReady(result) { result =>
result must equal (true)
}
}
}
}
