Question

我有以下父子关系

public class ParentActor extends UntypedActor {

    @Override
    public void onReceive(Object msg) throws Exception {

        if (msg instanceof Command) {
            final String data = ((Command) msg).getData();
            final Event event = new Event(data, UUID.randomUUID().toString());
ActorRef childActor = getContext().actorOf(Props.create(ChildActor.class), "child-actor");

            childActor.tell(event, getSelf());
        } else if (msg.equals("echo")) {
            log.info("ECHO!");
        }
    }
}
public class ChildActor extends UntypedActor {

    @Override
    public void onReceive(Object msg) {
        log.info("Received Event: " + msg);
        //PoisonPill and kill self
    }


}

如何在向父母发送消息后，编写一个观察和验证儿童演员死亡的测试？

我有以下结果导致断言超时

@Before
     childProps = Props.create(ForwarderActor.class, childProbe.getRef());
     childRef = TestActorRef.create(system, childProps);



  @Test
public void myTest () {
    underTest.tell("send parent message);
    childProbe.expectMsgClass(Terminated.class);
}

和货运代理人

import akka.actor.ActorRef;
import akka.actor.UntypedActor;


public class ForwarderActor extends UntypedActor {
    final ActorRef target;
    public ForwarderActor(ActorRef target) {
        this.target = target;
    }
    public void onReceive(Object msg) {
        target.forward(msg, getContext());
    }
}

我想这里的问题是我的孩子演员不是通过道具传递的，而是在父演员本身中初始化，这是一个糟糕的设计吗？我该如何测试这个设置？
