Combining FakeRouterModule and ScaldiApplicationBuilder.withScaldiInj

[Ulrik Lejon]

Hi

I need to create a test where I can inject stuff and also set up some fake routes (to fake an external web service).

I tried to do it like this:

"My service" should {

    val fakeRotes = FakeRouterModule {

            case ("POST", someUrl) =>

                Action { implicit request =>

                    BadRequest("Ops")

                }

    }

    "Do some stuff" in new TestContext {

        ScaldiApplicationBuilder.withScaldiInj(configuration = Configuration.from(DefaultConf.appCfg), modules = Seq(fakeRotes)) { implicit inj =>

               .....

        }

    }

}

However, I'm getting this when running the test: Connection refused: localhost/127.0.0.1:19001 (NettyConnectListener.java:128)

Is this suppose to work?

Cheers,

Ulrik

Sadly, I don't know why exactly this code gives Netty error, my wild guess would be that 'withScaldiInj' should surround The spec and not the other way around (you are running tests with sbt, aren't you?)

I've spent quite some time (not without Scaldi's creator help) to set up tests in my project. 

Here you may find the parent class of all specs in my project that automatically surrounds children's specs with application initialisations.

And here you may find an example of a spec that needs injector to be run.

Hope this will help, 

Alex

Thanx for sharing your specs, I will have a look at those.

Yes I'm running the tests with sbt. The problem is not that the spec is surrounding the 'withScaldiInj' block (it works in my other tests).

What makes this test "special" is that I need to run a server (TestServer), and not just an application. I also need to have access to the scaldi injector to be able to inject stuff in my test.

Hi Ulrik,

Since you need to access the `TestServer` I can recommend you to look at this example test:

https://github.com/scaldi/scaldi-play-example/blob/master/test/IntegrationSpec.scala#L29

It starts the server with fake routes. You also mentioned, that you need an injector in the test, because you need to inject some bindings. It's should be pretty easy achieve:

val fakeRotes = FakeRouterModule {

  case ("GET", "/some-url") => Action {

    Results.Ok("everything is fine")

  }

}

implicit val injector = new ScaldiApplicationBuilder(modules = Seq(fakeRotes)).buildInj()

import scaldi.Injectable._

running(TestServer(3333, inject [Application]), HTMLUNIT) { browser =>

  val someService = inject [SomeService]

  browser.goTo("http://localhost:3333/some-url")

  browser.pageSource must contain("everything is fine")

} 

Hope this helps.

Cheers,

Oleg
