Play Controllers functional test with PlaySpec - scala

Question

I'm using Play Scala 2.5, I would like to write functional tests for a controller class.
This is the signature of my controller class with a action I would like to test for example.
class MyController #Inject()(implicit context: ExecutionContext, val messagesApi: MessagesApi, val dao: Dao) extends Controller with I18nSupport {
def getMyData = Action.async { implicit request =>
dao.getMyData map { myData =>
Ok(views.html.render(myData))
}.recover {
// recover.
}
}
}
Here is my Dao class that is used in my controller's action :
import play.api.Configuration
class Dao #Inject()(val ws: WSClient, val configuration: Configuration) {
val myConfigData: List[MyConfigData] = { ... } // Get data from configuration
def getMyData(): Future[List[MyData]] = {
// use myConfigData and call web service (ws) to get some data
}
}
I would like to test my controller's action using different configuration in my Dao class.
I manage to do it and my test class is working but I would like some advices to improve the code.
package controllers
import play.core.server.Server
import org.scalatest._
import Inspectors._
import org.scalatestplus.play._
import play.api.routing.sird._
import play.api.libs.json._
import play.api.mvc._
import play.api.Play
import play.api.test._
import play.api.i18n.MessagesApi
import play.api.Configuration
import play.api.test.Helpers.{ OK, status, contentAsString }
import org.scalatest.concurrent.ScalaFutures
import scala.concurrent.Future
import scala.concurrent.Await
import scala.concurrent.duration._
import play.api.libs.json._
import play.api.mvc._
import scala.concurrent.ExecutionContext
import com.typesafe.config.ConfigFactory
import dao.{ Dao }
import akka.util.Timeout
class MyControllerFunctionalSpec extends PlaySpec with OneAppPerSuite with ScalaFutures {
implicit val messagesApi = app.injector.instanceOf[MessagesApi]
implicit val ec = app.injector.instanceOf[ExecutionContext]
implicit val timeout = Timeout(5 seconds)
trait OneConfig {
val config = ConfigFactory.parseString(""" my config """)
}
trait AnotherConfig {
val config = ConfigFactory.parseString(""" my other config """)
}
"MyController" should {
"get some data" in new OneConfig {
Server.withRouter() {
case GET(p"/url1/some/data") => Action {
Results.Ok(Json.arr(Json.obj("name" -> "data1")))
}
} { implicit port =>
WsTestClient.withClient { client =>
implicit val dao = new Dao(client, Configuration(config))
val myController = new MyController()
val result = myController.getMyData(FakeRequest())
status(result) must equal(OK)
//println(contentAsString(result))
}
}
}
}
}
It is working like this but I was guided by compilation error and by fixing them to get it to work.
I would like help or advices to do it the right way.
Any advice welcome.
