Menulis ScalaTest untuk ReactiveMongoApi di Playframework 2.4?

Saya mencoba untuk mulai menulis tes untuk mongodb di aplikasi bermain saya.

Tampaknya saya tidak dapat menjalankannya karena koneksi dimatikan sebelum penyimpanan dijalankan.

Inilah hasilnya

[info] UserDaoMongoSpec:
[info] UserDao
[info] - application - ReactiveMongoApi starting...
[info] - application - ReactiveMongoApi successfully started with DB 'test'! Servers:
            [localhost:27017]
[info] - should save users and find them by userId
[info] - application - ReactiveMongoApi stopping...
[info] - application - ReactiveMongoApi connections stopped. [Success(Closed)]
[INFO] [12/24/2015 15:36:43.961] [reactivemongo-akka.actor.default-dispatcher-4] [akka://reactivemongo/user/Monitor-3] Message [reactivemongo.core.actors.Close$] from Actor[akka://reactivemongo/deadLetters] to Actor[akka://reactivemongo/user/Monitor-3#1192398481] was not delivered. [1] dead letters encountered. This logging can be turned off or adjusted with configuration settings 'akka.log-dead-letters' and 'akka.log-dead-letters-during-shutdown'.
[info] ScalaTest
[info] Run completed in 3 seconds, 989 milliseconds.
[info] Total number of tests run: 1

[info] Tests: succeeded 1, failed 0, canceled 0, ignored 0, pending 0
[info] All tests passed.
[info] Passed: Total 1, Failed 0, Errors 0, Passed 1

Ini adalah kode pengujiannya, yang tidak menguji apa pun, tetapi saya mencoba menulis databasenya terlebih dahulu.

package test.daos

import scala.concurrent.ExecutionContext.Implicits.global

import daos.impl.UserDaoMongo

import org.scalatest._
import play.api.test._
import play.api.test.Helpers._
import org.scalatestplus.play._

class UserDaoMongoSpec extends DaosApplicationSpecOneAppPerTest {

  "UserDao" should {
    "save users and find them by userId" in {
      val userDao = new UserDaoMongo
      val future = for {
        _ <- userDao.save(credentialsTestUser)
        maybeUser <- userDao.find(credentialsTestUser.id)
      } yield maybeUser.map(_ == credentialsTestUser)
    }
  }

}

Dan implementasi dao

package daos.impl

import java.util.UUID

import scala.concurrent.Future

import play.api.Play.current
import play.api.libs.concurrent.Execution.Implicits.defaultContext
import play.api.libs.json.Json

import play.modules.reactivemongo.ReactiveMongoApi
import play.modules.reactivemongo.json._
import play.modules.reactivemongo.json.collection.JSONCollection

import com.mohiva.play.silhouette.api.LoginInfo

import models.{User, Profile}
import models.User._

import daos.api.UserDao

import play.api.Logger

class UserDaoMongo extends UserDao {
  lazy val reactiveMongoApi = current.injector.instanceOf[ReactiveMongoApi]
  val users = reactiveMongoApi.db.collection[JSONCollection]("users")

  def find(loginInfo:LoginInfo):Future[Option[User]] =
    users.find(Json.obj("profiles.loginInfo" -> loginInfo)).one[User]

  def find(userId:UUID):Future[Option[User]] ={
    Logger.debug("AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA")
    users.find(Json.obj("id" -> userId)).one[User]
  }

  def save(user:User):Future[User] =
    users.insert(user).map(_ => user)

  def confirm(loginInfo:LoginInfo):Future[User] = for {
    _ <- users.update(Json.obj(
      "profiles.loginInfo" -> loginInfo
    ), Json.obj("$set" -> Json.obj("profiles.$.confirmed" -> true)))
    user <- find(loginInfo)
  } yield user.get

  def link(user:User, profile:Profile) = for {
    _ <- users.update(Json.obj(
      "id" -> user.id
    ), Json.obj("$push" -> Json.obj("profiles" -> profile)))
    user <- find(user.id)
  } yield user.get

  def update(profile:Profile) = for {
    _ <- users.update(Json.obj(
      "profiles.loginInfo" -> profile.loginInfo
    ), Json.obj("$set" -> Json.obj("profiles.$" -> profile)))
    user <- find(profile.loginInfo)
  } yield user.get
}

Apa yang mungkin saya lakukan salah?

Terima kasih
