如何测试依赖注入创建的actor?在我的应用程序中,我可以通过命名注入获得ActorRef:
public MyClass { @Inject @Named("ping") ActorRef mPingRef; } 如何在我的测试中获得此参考? 这是我的演员: public class PingActor extends UntypedActor { @Inject public PingActor(Configuration configuration) { ... // Use config } @Override public void onReceive(Object message) throws Exception { if (message instanceof Ping) { getSender().tell(new Pong(),getSelf()); } } public static class Ping {} public static class Pong {} } 我已经使用自己的模块配置了我的应用程序: public class MyModule extends AbstractModule implements AkkaGuiceSupport { private final Configuration mConfig; public MyModule(Environment environment,Configuration configuration){ this.mConfig = configuration; } @Override protected void configure() { bindActor(PingActor.class,"ping"); } } 该模块在application.conf中启用: play.modules.enabled += "com.my.package.MyModule"
这个解决方案适用于PlayScala,但它应该与PlayJava的机制相同:
所以我得到了我的GuiceModule: class CommonModule extends AbstractModule with AkkaGuiceSupport { override def configure(): Unit = { bindActor[SomeActor]("actor-name") } } 然后测试(我从我的测试中删除了一些东西,所以它可能无法直接编译): import akka.actor.{ActorRef,ActorSystem} import akka.testkit.{TestKit,TestProbe} import module.CommonModule import org.specs2.mutable.Specification import org.specs2.specification.Scope import play.api.inject._ import play.api.inject.guice.GuiceApplicationBuilder import play.api.test.Helpers._ class SwitchUpdateActorSpec extends Specification { "MyActor" should { val actorSystem = ActorSystem("test") class Actors extends TestKit(actorSystem) with Scope val app = new GuiceApplicationBuilder(modules = Seq(new CommonModule)) .overrides(bind[ActorSystem].toInstance(actorSystem)) .build() "respond with 'ok' upon receiving a message" in new Actors { running(app) { private val injector: Injector = app.injector private val actor: ActorRef = injector.instanceOf(BindingKey(classOf[ActorRef]).qualifiedWith("actor-name")) val probe = TestProbe() actor.tell("hi there!",probe.ref) probe.expectMsg("ok") } } } } 所以我做的是: >创建一个全新的ActorSystem 当您查看在MyModule.configure()方法中使用的bindActor的实现时,会发生很明显的情况: def bindActor[T <: Actor: ClassTag](name: String,props: Props => Props = identity): Unit = { accessBinder.bind(classOf[ActorRef]) .annotatedWith(Names.named(name)) .toProvider(Providers.guicify(Akka.providerOf[T](name,props))) .asEagerSingleton() } (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
