Scala 如何解决akka http测试和akka测试包中ActorSystem的冲突

我有一个测试类，其中我需要同时使用和
所以我就是这样做的

class MyTest extends TestKit(ActorSystem("testsys")) with ScalaFutures with ImplicitSender with AnyWordSpecLike with Matchers with BeforeAndAfterAll with ScalatestRouteTest { 

//tests here
}

    class MyTest extends TestKit(ActorSystem("testsys")) with ScalaFutures with ImplicitSender with AnyWordSpecLike with Matchers with BeforeAndAfterAll with ScalatestRouteTest { 
override def createActorSystem(): ActorSystem = system
  override implicit val system: ActorSystem = createActorSystem

    //tests here
    }

但是我得到了一个编译时错误

implicit val system: akka.actor.ActorSystem (defined in class TestKit) and
[error]   implicit val system: akka.actor.ActorSystem (defined in trait RouteTest)
[error]   (note: this can be resolved by declaring an `override` in class MyTest.)
[error] class InsertEventTest extends TestKit(ActorSystem("testinterpret")) with ScalaFutures with ImplicitSender with AnyWordSpecLike with Matchers with BeforeAndAfterAll with ScalatestRouteTest {
[error]       ^

(note: this can be resolved by declaring an `override` in class InsertEventTest.)

所以我做了类似的事情

class MyTest extends TestKit(ActorSystem("testsys")) with ScalaFutures with ImplicitSender with AnyWordSpecLike with Matchers with BeforeAndAfterAll with ScalatestRouteTest { 

//tests here
}

    class MyTest extends TestKit(ActorSystem("testsys")) with ScalaFutures with ImplicitSender with AnyWordSpecLike with Matchers with BeforeAndAfterAll with ScalatestRouteTest { 
override def createActorSystem(): ActorSystem = system
  override implicit val system: ActorSystem = createActorSystem

    //tests here
    }

但是我得到了

NullPointerException

为什么您要对

TestKit

和

RouteTest

进行测试？这似乎是设计上的缺陷。这两种测试类型不是设计为在同一个类中共存的。你能把它们分成两个测试类吗？为什么你要同时测试
