我想用 ScalatestRouteTest 测试路由，如下所示:
trait MyRoutes extends Directives {
self: Api with ExecutionContextProvider =>
val myRoutes: Route =
pathPrefix("api") {
path("") {
(get & entity(as[MyState])) {
request => {
complete(doSomething(request.operation))
}
}
}
}
}
}
class RoutesSpec extends WordSpecLike with Api with ScalatestRouteTest
with Matchers with MyRoutes with MockitoSugar {
"The Routes" should {
"return status code success" in {
Get() ~> myRoutes ~> check {
status shouldEqual StatusCodes.Success
}
}
}
}
运行测试时出现运行时错误:
Could not run test MyRoutesSpec: org.jboss.netty.channel.ChannelException: Failed to bind to: /127.0.0.1:2552
我不想绑定(bind)到本地主机。如何实现？
最佳答案
解决方案是禁用远程处理和集群(这是在单独的配置文件中启用的)并使用默认提供程序。
actor remoting 和 clustering 与正在运行的应用程序冲突(为路由测试启动)。它们采用相同的配置，因此都尝试使用相同的端口，但会发生冲突。
在 trait MyRoutes 中添加了以下代码以使其工作:
// Quick hack: use a lazy val so that actor system can "instantiate" it
// in the overridden method in ScalatestRouteTest while the constructor
// of this class has not yet been called.
lazy val routeTestConfig =
"""
| akka.actor.provider = "akka.actor.LocalActorRefProvider"
| persistence.journal.plugin = "akka.persistence.journal.inmem"
""".stripMargin
override def createActorSystem(): ActorSystem =
ActorSystem("RouteTest", ConfigFactory.parseString(routeTestConfig))
