这是Play 2.1.3的已知问题。同时，有一种解决方法。将以下内容添加到val main函数的Build.scala文件中：
val main = play.Project(appName, appVersion, appDependencies).settings( // Add your own project settings here testOptions in Test ~= { args => for { arg <- args val ta: Tests.Argument = arg.asInstanceOf[Tests.Argument] val newArg = if(ta.framework == Some(Testframeworks.JUnit)) ta.copy(args = List.empty[String]) else ta } yield newArg })
