Another utility actor used in unit testing. Use this when you need to refer to the actor being tested by its path, but don't want to create all the actor parent actors.

ChildCreationActor.java

package com.turbo.akka;

import akka.actor.ActorRef;
import akka.actor.Props;
import akka.actor.UntypedActor;
import akka.event.Logging;
import akka.event.LoggingAdapter;

/**
 * Utility actor that does nothing but take a Props and create
 * whatever actor the Props points to
 */
public class ChildCreationActor extends UntypedActor {
    private final LoggingAdapter LOG = Logging.getLogger(getContext().system(), this);

    @Override
    public void onReceive(Object o) throws Exception {
        if (o instanceof ChildArgs) {
            ChildArgs childArgs = (ChildArgs)o;
            ActorRef child = getContext().actorOf(childArgs.props, childArgs.actorName);
            LOG.info("Created child actor: " + child.path().toString());
        }
        else {
            unhandled(o);
        }
    }

    /**
     * The only usable msg to ChildCreationActor. Defines the child actor to create
     */
    public static class ChildArgs {
        public final String actorName;
        public final Props props;

        public ChildArgs(Props props, String actorName) {
            this.actorName = actorName;
            this.props = props;
        }
    }
}

Thank you!
