Akka Java创建带有路径的testprobe引用?
我对akka的测试还是有点陌生。在我正在构建的系统中,我正在做一些Akka Java创建带有路径的testprobe引用?,java,testing,akka,Java,Testing,Akka,我对akka的测试还是有点陌生。在我正在构建的系统中,我正在做一些 private void tellPublisherAboutUpdates(Map<String,Update> updates){ if(updates.isEmpty()){ getContext().actorSelection(ActorSelectionPath.UPDATE_PUBLISHER.path()).tell(new InfoMessage<Ma
private void tellPublisherAboutUpdates(Map<String,Update> updates){
if(updates.isEmpty()){
getContext().actorSelection(ActorSelectionPath.UPDATE_PUBLISHER.path()).tell(new InfoMessage<Map<String,Update>>(updates), getSelf());
}
}
private void tellisheraboutupdates(地图更新){
if(updates.isEmpty()){
getContext().actorSelection(ActorSelectionPath.UPDATE_PUBLISHER.path()).tell(newinfomessage(updates),getSelf());
}
}
现在,我的第一个想法是,使用TestProbe创建一个带有相关路径的测试引用,但我不知道如何做到这一点?如果有一种替代方法更适合测试这种交互,我也很想了解它 我用来解决这个问题的模式包括创建一个转发参与者,如下所示:
**
* Simple actor that takes another actor and forwards all messages to it.
* Useful in unit testing for capturing and testing if a message was received.
* Simply pass in an Akka JavaTestKit probe into the constructor, and all messages
* that are sent to this actor are forwarded to the JavaTestKit probe
* Ref: https://gist.github.com/jconwell/8153535
*/
public class ForwardingActor extends UntypedActor {
final ActorRef target;
public ForwardingActor(ActorRef target) {
this.target = target;
}
@Override
public void onReceive(Object msg) {
target.forward(msg, getContext());
}
}
然后可以像这样使用它来注入探针引用:
JavaTestKit probe = new JavaTestKit(actorSystem);
actorSystem.actorOf(Props.create(ForwardingActor.class, probe.getRef()), "myActor");
当您希望您的角色是当前角色的子角色或顶级角色时,这可以正常工作,但如果您的角色路径引用嵌套在层次结构中的角色,则可能会有点棘手。我结合使用ForwardingActor和ChildCreationActor()来解决这个问题
我通过这个博客了解到了上述技术:是的,我以前用过几次这种模式。我希望有更地道的方法,谢谢,这是我目前知道的唯一方法……我也对这种方法的任何改进感兴趣
