我正在编写一个测试用例来测试 akka 演员。但是,我必须在假应用程序之外创建一个单独的 Akka 系统。有没有办法从 FakeApplication 获取 akka 演员系统?
public class ChannelWorkerTest {
    private TestActorRef<ChannelWorker> actorRef;
    private ActorSystem actorSystem;
    @Before
    public void initActor() {
        actorSystem = ActorSystem.apply();
        actorRef = TestActorRef.apply(new Props(ChannelWorker.class), actorSystem);
    }
    @Test
    public void calculatePiFor1() {
        running(fakeApplication(TestConf.getConf()), new Runnable() {
            public void run() {
              TestProbe testProbe = TestProbe.apply(actorSystem);
              .....
              actorRef.tell(aMessage, testProbe.ref());
              }
        });
    }
    @After
    public void shutdownActorSystem() {
        actorSystem.shutdown();
    }
}
