Testing Controller action in play framework 2.4 wih scalatest - scala

Question

I am trying to test my controller action in Play Framework with ScalaTest .
I have read play documentation and trying to run the given sample to get started
my controller Application.scala
class Application extends Controller {
def index1() = Action{
Ok("ok")
}
test class
import scala.concurrent.Future
import org.scalatestplus.play._
import play.api.mvc._
import play.api.test._
import play.api.test.Helpers._
import akka.stream.Materializer
import play.api.libs.json.Json
class ExampleController extends PlaySpec with Results {
"testing the index page" should {
"the test should be valid" in {
val controller = new controllers.Application()
val result: Future[Result] = controller.index1().apply(FakeRequest())
val bodyText: String = contentAsString(result)
bodyText mustBe "ok"
}
}
}
and i am getting following exception while running the test
ExampleController:
