函数的模拟函数参数

Question

我正在使用Scala，Play Framework开发web应用程序。我需要用自定义操作来测试控制器。请看代码：

package controllers.helpers 

import play.api.mvc.{ActionBuilder, Request, Result} 

import scala.concurrent.Future 

class CustomAction extends ActionBuilder[Request] { 

    override def invokeBlock[A](request: Request[A], block: (Request[A]) => Future[Result]): Future[Result] = { 
    // do some stuff 
    block(request) 
    } 
} 


package controllers 

import javax.inject.Singleton 

import play.api.mvc.Controller 

@Singleton 
class SomeController @Inject() (customAction: CustomAction 
          ) extends Controller { 

    def foo() = customAction(parse.json) { implicit request => 
    // do some stuff and create result 
    } 
} 

下面你可以找到测试类的代码。我用Specs2和我上线了org.mockito.exceptions.misusing.InvalidUseOfMatchersException与customeActionMock.invokeBlock(any[Request[_]], any[(Request[_]) => Future[Result]]) returns mock[Future[Result]]

package controllers 
import controllers.helpers.CustomAction 
import org.specs2.mock.Mockito 
import play.api.mvc.{Request, Result} 
import play.api.test.{FakeHeaders, FakeRequest, PlaySpecification} 

import scala.concurrent.Future 

class SomeControllerSpec extends PlaySpecification with Mockito { 
    private val customeActionMock = mock[CustomAction] 
    customeActionMock.invokeBlock(any[Request[_]], any[(Request[_]) => Future[Result]]) returns mock[Future[Result]] //this doesn't work, exception is thrown there 


    "SomController" should { 
    "respond Ok on valid request" in { 
     val result = new UserController(customeActionMock).foo()(FakeRequest()) 
     status(result) shouldEqual OK 
    } 
    } 
} 

我明白，我嘲笑CustomAction正确的block参数。有人可以帮助我做到这一点吗？

Answer 1

不要嘲笑CustomAction：

class SomeControllerSpec extends PlaySpecification with Mockito { 
    private val customeActionMock = new CustomAction 


    "SomController" should { 
    "respond Ok on valid request" in { 
     val result = new UserController(customeActionMock).foo()(FakeRequest()) 
     status(result) shouldEqual OK 
    } 
    } 
}

我的项目使用播放2.5.x.我使用scalatest。这是我如何测试控制器。

import org.scalatestplus.play.OneAppPerSuite 
import org.scalatest._ 
import org.scalatest.time.{Millis, Seconds, Span} 
import org.scalatest.concurrent.ScalaFutures 
import scala.concurrent.Future 

class SomeControllerSpec extends FlatSpec with Matchers with ScalaFutures with OneAppPerSuite { 
private val customeActionMock = new CustomAction // create an instance of a class 
implicit val defaultPatience = PatienceConfig(timeout = Span(5,Seconds), interval = Span(500, Millis)) 

it should "respond Ok on valid request" in { 
    val resultF : Future[Result] = new UserController(customeActionMock).foo()(FakeRequest()) 
    whenReady(resultF) { resultR => 
     resultR.header.status shouldBe 200 
    } 
    } 
}
