运行简单喷雾路由测试结果:无法初始化类spray.http.Uri$
提问于 2015-03-06 03:29:27
我对spray还是个新手。我试图正确地进行测试，所以我使用了spary testkit中显示的示例，但是我得到了这个错误。我们将非常感谢您的帮助：

return a MethodNotAllowed error for PUT requests to the root path这是测试类
class RouteTester extends Specification with Specs2RouteTest with HttpService {
def actorRefFactory = system // connect the DSL to the test ActorSystem
val smallRoute =

} ~
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"
}
}
}
}我使用的是maven，这是依赖项和版本。

最近，我在各种测试套件中苦苦挣扎，最终使用了纯Akka TestKit，因为split迫使我将HttpServiceActors拆分成独立的特征和演员，这对我来说是不可接受的。
我可以分享一些代码作为灵感，你可以试一试(除非有人提出更好的答案)：
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)
}

解决了！问题是依赖项需要不同的版本。也就是说，喷雾-can和喷雾-路由工件都依赖于scala 2.10，而其余的声明依赖于scala 2.11。
我所要做的就是将依赖项更改为：
<scalaBinaryVersion>2.11</scalaBinaryVersion>
<dependency>
<groupId>io.spray</groupId>
<artifactId>spray-can_${scalaBinaryVersion}</artifactId>
<version>${spray.version}</version>
</dependency>
<dependency>
<groupId>io.spray</groupId>
<artifactId>spray-routing_${scalaBinaryVersion}</artifactId>
<version>${spray.version}</version>
</dependency>问题解决了！
