Scala 在SBT中执行测试失败的任务依赖项

如果我的测试成功完成，将执行我build.sbt中的以下代码。它播放了一段美妙的小调，告诉我我的测试成功完成了，让我不再像肮脏的哈利一样盯着终端看

test <<= (test in Test) map { result =>
  import java.io.File
  import javax.sound.sampled._
  val clip = AudioSystem.getClip();
  val soundfile = new File("success.wav")
  val inputStream = AudioSystem.getAudioInputStream(soundfile);
  clip.open(inputStream);
  clip.start();
  result
}

测试参见。比如说,

... test in Test mapR {
  case Inc(inc: Incomplete) =>
     ... play failure sound ...
     throw inc
  case Value(v) =>
     ... play success sound ...
     v
}

看。比如说,

... test in Test mapR {
  case Inc(inc: Incomplete) =>
     ... play failure sound ...
     throw inc
  case Value(v) =>
     ... play success sound ...
     v
}
