Scala 测试中，自定义喷洒拒绝处理程序工作不正常

我正在使用

spray

构建一些JSON HTTP服务，在测试

RejectionHandler

时遇到了一些问题。如果我启动运行命令

sbt run

的应用程序并发出请求，则

RejectionHandler

会按预期处理

MalformedRequestContentRejection

，但即使在密封路由的情况下运行测试时，我也会收到

IllegalArgumentException

。另一方面，

MethodRejection

工作正常。JSON验证使用

require

下一个示例基于带有POST端点和新测试的spray-can 1.3\u scala-2.11上的

spray template

分支

。我用整个例子做了一个叉子

注意，反序列化JSON使用了
case-clase
，验证使用了
require
方法，并声明了隐式
RejectionHandler

package com.example

import akka.actor.Actor
import spray.routing._
import spray.http._
import StatusCodes._
import MediaTypes._
import spray.httpx.SprayJsonSupport._

class MyServiceActor extends Actor with MyService {
  def actorRefFactory = context
  def receive = runRoute(myRoute)
}

case class SomeReq(field: String) {
  require(!field.isEmpty, "field can not be empty")
}
object SomeReq {
  import spray.json.DefaultJsonProtocol._
  implicit val newUserReqFormat = jsonFormat1(SomeReq.apply)
}

trait MyService extends HttpService {
  implicit val myRejectionHandler = RejectionHandler {
    case MethodRejection(supported) :: _ => complete(MethodNotAllowed, supported.value)
    case MalformedRequestContentRejection(message, cause) :: _ => complete(BadRequest, "requirement failed: field can not be empty")
  }
  val myRoute =
    pathEndOrSingleSlash {
      post {
        entity(as[SomeReq]) { req =>
          {
            complete(Created, req)
          }
        }
      }
    }
}

这是使用
spray testkit
实施的测试。最后一个需要一个
BadRequest
，但测试失败，出现
IllegarArgumentException

package com.example

import org.specs2.mutable.Specification
import spray.testkit.Specs2RouteTest
import spray.http._
import StatusCodes._
import spray.httpx.SprayJsonSupport._

class MyServiceSpec extends Specification with Specs2RouteTest with MyService {
  def actorRefFactory = system

  "MyService" should {
    "leave GET requests to other paths unhandled" in {
      Get("/kermit") ~> myRoute ~> check {
        handled must beFalse
      }
    }
    "return a MethodNotAllowed error for PUT requests to the root path" in {
      Put() ~> sealRoute(myRoute) ~> check {
        status should be(MethodNotAllowed)
        responseAs[String] === "POST"
      }
    }
    "return Created for POST requests to the root path" in {
      Post("/", new SomeReq("text")) ~> myRoute ~> check {
        status should be(Created)
        responseAs[SomeReq] === new SomeReq("text")
      }
    }
    /* Failed test. Throws IllegalArgumentException */
    "return BadRequest for POST requests to the root path without field" in {
      Post("/", new SomeReq("")) ~> sealRoute(myRoute) ~> check {
        status should be(BadRequest)
        responseAs[String] === "requirement failed: field can not be empty"
      }
    }
  }
}

我错过了什么

提前谢谢
 您的
SomeReq
类正在
Post（“/”），new SomeReq（“”）请求生成器中被急切地实例化，并且
require
方法在
类
实例化后立即被调用

要解决此问题，请尝试使用以下方法：

import spray.json.DefaultJsonProtocol._
Post("/", JsObject("field" → JsString(""))) ~> sealRoute(myRoute) ~> check {
  status should be(BadRequest)
  responseAs[String] === "requirement failed: field can not be empty"
}

谢谢工作起来很有魅力。
