私はスプレーにかなり慣れていません。テストを正しく取得しようとしているので、Spary テストキットに示されている例を使用しましたが、このエラーが発生しています。どんな援助でも大歓迎です:

The service should

return a MethodNotAllowed error for PUT requests to the root path

これはテストクラスです

class RouteTester extends Specification with Specs2RouteTest with HttpService {
  def actorRefFactory = system // connect the DSL to the test ActorSystem

  val smallRoute =
    get {
      pathSingleSlash {
        complete {
          <html>
            <body>
              <h1>Say hello to <i>spray</i>!</h1>
            </body>
          </html>
        }
      } ~
        path("ping") {
          complete("PONG!")
        }
    }

  "The service" should {

    "return a greeting for GET requests to the root path" in {
      Get() ~> smallRoute ~> check {
        responseAs[String] must contain("Say hello")
      }
    }

    "return a 'PONG!' response for GET requests to /ping" in {
      Get("/ping") ~> smallRoute ~> check {
        responseAs[String] === "PONG!"
      }
    }

    "leave GET requests to other paths unhandled" in {
      Get("/kermit") ~> smallRoute ~> check {
        handled must beFalse
      }
    }

    "return a MethodNotAllowed error for PUT requests to the root path" in {
      Put() ~> sealRoute(smallRoute) ~> check {
        status === MethodNotAllowed
        responseAs[String] === "HTTP method not allowed, supported methods: GET"
      }
    }
  }
}

最近、私はさまざまなテストキットに苦労しすぎて、最終的に純粋な Akka TestKit を使用することになりました。なぜなら、Spray TestKit により、HttpServiceActors を別々のトレイトとアクターに分割する必要があり、これは私には受け入れられませんでした。

インスピレーションのためにいくつかのコードを共有できます。試してみてください（誰かがより良い答えを出さない限り）：

RestInterface.scala:

import spray.routing.HttpServiceActor

class RestInterface extends HttpServiceActor {
  override def receive: Receive = runRoute(smallRoute)
  val smallRoute =
    get {
      pathSingleSlash {
        complete {
          <html>
            <body>
              <h1>Say hello to <i>spray</i>!</h1>
            </body>
          </html>
        }
      } ~
      path("ping") {
        complete("PONG!")
      }
    }
}

RestInterfaceSpec.scala:

import akka.actor.{Props, ActorSystem}
import akka.testkit.{TestActorRef, ImplicitSender, TestKit}
import org.scalatest.{BeforeAndAfterAll, Matchers, WordSpecLike}
import spray.http.HttpResponse
import spray.httpx.RequestBuilding

class RestInterfaceSpec(_system: ActorSystem) extends TestKit(_system) with ImplicitSender with WordSpecLike with Matchers with BeforeAndAfterAll with RequestBuilding with SpecHelper {
  def this() = this(ActorSystem("MySpec"))

  "The service" must {
    "return a response" in {
      val service = TestActorRef[RestInterface]
      service ! Get("/")
      expectMsgType[HttpResponse]
    }
  }
}

SpecHelper.scala:

import akka.actor.ActorSystem
import akka.testkit.TestKit

trait SpecHelper extends BeforeAndAfterAll { this: Suite =>
  implicit val system: ActorSystem

  override def afterAll(): Unit = {
    TestKit.shutdownActorSystem(system)
  }
}
