scala – 如何在Play 2.0.1中使用TestServer运行多个功能规范？

代码段：

trait CommonSteps extends BaseSpecfication {
  val testServer: TestServer = TestServer(3333)
  val testServerBaseURL: String = "http://localhost:3333/"

  override def map(fs: => Fragments) =
    Step(testServer.start()) ^ super.map(fs) ^ Step(testServer.stop())

}

class FunctionalTest1 extends Specification with CommonSteps { def is =
  ...

  ... extends When[...] {
    val browser: TestBrowser = TestBrowser.of(HTMLUNIT)
    browser.goTo(testServerBaseURL + "/some_path")
    browser
  }

  ... extends Then[...] {
    browser.await.until("element that is loaded on ajax request").isPresent()
    ...
  }

}

我们得到错误：

虽然测试在隔离运行时有效,但是当它们中的两个或多个一起运行时会出现错误.

它似乎与this issue有关,虽然我的例子是Scala Play应用程序.任何人都可以确认此问题已在较新版本的Play中修复吗？或者,是否有一种解决方法可以避免在Play 2.0.1中出现此错误.
