单元测试 akka actor 方法

Question

我有一个形式的演员：

class TestActor(repo: Repo) extends Actor {
implicit val executionContext: ExecutionContext = context.dispatcher
def receive: Receive = {
...
}
def testMethod(stringSeq: Seq[String]): String =
...
}
}

我只想测试方法测试方法。

我正在尝试将测试用例编写为：

class TestActorSpec
extends TestKit(ActorSystem("TestActorSpec"))
with WordSpecLike
with Matchers
with JsonSupport
with MockitoSugar
with BeforeAndAfterAll
with ImplicitSender {
override def afterAll: Unit = TestKit.shutdownActorSystem(system)
implicit val futureDuration: FiniteDuration = 60.seconds
implicit val timeout: Timeout               = 10.seconds
val mockedRepo               = mock[Repo]
val testActorRef: ActorRef = system.actorOf(
TestActor.props(mockedRepo)
)
"TestActorSpec" should {
"be able to get data " in {
}
}
}

如何从 testActorRef 访问方法测试方法？

我也试过：

TestActorRef[TestActor].underlyingActor.testMethod(Seq("data"))

它对我不起作用。

Actor应该通过你发送给他们的消息来测试他们。但是，如果方法不访问任何特定于参与者的值，例如context，您仍然可以单独测试方法。

您可以将testMethod移动到伴随对象并从那里进行测试。

class TestActor(repo: Repo) extends Actor {
implicit val executionContext: ExecutionContext = context.dispatcher
def receive: Receive = {
//    call  TestActor.testMethod
}
}
object TestActor {
def testMethod(stringSeq: Seq[String]): String = ???
}
