如何在Akka演员中测试公共方法？ [英] How to test a public method in an akka actor?

问题描述

我有一个闲话演员：

class MyActor extends Actor {
  def recieve { ... }

  def getCount(id: String): Int = {
    //do a lot of stuff
    proccess(id)
    //do more stuff and return
  }
}

我正在尝试为getCount方法创建单元测试：

I am trying to create a unit test for the getCount method:

it should "count" in {
    val system = ActorSystem("Test")
    val myActor = system.actorOf(Props(classOf[MyActor]), "MyActor")

    myActor.asInstanceOf[MyActor].getCount("1522021") should be >= (28000)
}

但它不起作用：

  java.lang.ClassCastException: akka.actor.RepointableActorRef cannot be cast to com.playax.MyActor

如何测试此方法？

推荐答案

执行以下操作：

import org.scalatest._
import akka.actor.ActorSystem
import akka.testkit.TestActorRef
import akka.testkit.TestKit

class YourTestClassTest extends TestKit(ActorSystem("Testsystem")) with FlatSpecLike with Matchers {

  it should "count plays" in {
    val actorRef = TestActorRef(new MyActor)
    val actor = actorRef.underlyingActor
    actor.getCount("1522021") should be >= (28000)
  }
}
