Scala播放框架-获取“；计时器关闭后无法排队“；运行涉及Akka的测试时出错

当尝试对运行Akka调度程序的代码（使用Mockito）进行单元测试时，我总是得到“计时器关闭后无法排队”

我的代码：

Global.scala

override def onStart(app: Application){
    Some(Akka.system.scheduler.schedule(23.hours, 24.hours) {
         println("I run all the time")
    })
}

def insertTestData() = {
    running(FakeApplication()) {
       //some code
    }
}

object Global extends Global

trait Global extends GlobalSettings { ... }

object FakeGlobal extends Global {
  override def onStart(app: Application): Unit = {}
  override def onStop(app: Application): Unit = {}
}

object Fake {
  // This has to be a method, cannot be a value
  def application() = FakeApplication(withGlobal = Some(FakeGlobal))
}

def insertTestData() = {
  running(Fake.application()) {
    //some code
  }
}

任务存储规范scala

override def onStart(app: Application){
    Some(Akka.system.scheduler.schedule(23.hours, 24.hours) {
         println("I run all the time")
    })
}

def insertTestData() = {
    running(FakeApplication()) {
       //some code
    }
}

object Global extends Global

trait Global extends GlobalSettings { ... }

object FakeGlobal extends Global {
  override def onStart(app: Application): Unit = {}
  override def onStop(app: Application): Unit = {}
}

object Fake {
  // This has to be a method, cannot be a value
  def application() = FakeApplication(withGlobal = Some(FakeGlobal))
}

def insertTestData() = {
  running(Fake.application()) {
    //some code
  }
}

当我跑步时：

activator test

我得到：

我使用play 2.4

任何帮助都将不胜感激

很抱歉，我没有找到解决方案，只是找到了一个解决办法。它包括在

onStart（）

和

onStop（）

方法为空的测试中使用假

Global

对象

首先，您需要将

Global

对象拆分为trait和空对象：

Global.scala

override def onStart(app: Application){
    Some(Akka.system.scheduler.schedule(23.hours, 24.hours) {
         println("I run all the time")
    })
}

def insertTestData() = {
    running(FakeApplication()) {
       //some code
    }
}

object Global extends Global

trait Global extends GlobalSettings { ... }

object FakeGlobal extends Global {
  override def onStart(app: Application): Unit = {}
  override def onStop(app: Application): Unit = {}
}

object Fake {
  // This has to be a method, cannot be a value
  def application() = FakeApplication(withGlobal = Some(FakeGlobal))
}

def insertTestData() = {
  running(Fake.application()) {
    //some code
  }
}

然后在测试代码中，您可以创建一个假的

全局
：

假。scala

override def onStart(app: Application){
    Some(Akka.system.scheduler.schedule(23.hours, 24.hours) {
         println("I run all the time")
    })
}

def insertTestData() = {
    running(FakeApplication()) {
       //some code
    }
}

object Global extends Global

trait Global extends GlobalSettings { ... }

object FakeGlobal extends Global {
  override def onStart(app: Application): Unit = {}
  override def onStop(app: Application): Unit = {}
}

object Fake {
  // This has to be a method, cannot be a value
  def application() = FakeApplication(withGlobal = Some(FakeGlobal))
}

def insertTestData() = {
  running(Fake.application()) {
    //some code
  }
}

最后在测试中使用它：

任务存储规范scala

override def onStart(app: Application){
    Some(Akka.system.scheduler.schedule(23.hours, 24.hours) {
         println("I run all the time")
    })
}

def insertTestData() = {
    running(FakeApplication()) {
       //some code
    }
}

object Global extends Global

trait Global extends GlobalSettings { ... }

object FakeGlobal extends Global {
  override def onStart(app: Application): Unit = {}
  override def onStop(app: Application): Unit = {}
}

object Fake {
  // This has to be a method, cannot be a value
  def application() = FakeApplication(withGlobal = Some(FakeGlobal))
}

def insertTestData() = {
  running(Fake.application()) {
    //some code
  }
}

它对我有用。希望有帮助
 在游戏2.3中也有同样的问题，我实际上使用了游戏2.4
