specs2 After 方法在示例之前运行 [英] specs2 After method runs before the example

问题描述

我有以下测试:

class Foo extends mutable.SpecificationWithJUnit {
sequential

"this example should run before the 'After' method" in new Context {
    bar must beSome
}

class Context extends mutable.BeforeAfter with mutable.Around {

  override def apply[T : AsResult](a: =>T): Result = {
  lazy val result = super[Around].apply(a)
  super[BeforeAfter].apply(result)
  }

  override def delayedInit(x: => Unit): Unit = around { try { before; x; Success() } finally { after }}

  @Resource var barReader : BarReader = _

  val bar = barReader.someBar

  override def before : Any = { //some stuff}

  def after: Any = {
    bar = None
  }

  override def around[T : AsResult](t: =>T) = {
     //spring context injection logic
     AsResult.effectively(t)
  }

  }
}
}

我希望这个测试能够通过，但实际上发生的情况是由于延迟的 init，之后在示例之前运行.如果我将 Context 更改为 trait，我将失去延迟的 init 功能.这是错误还是我做错了什么?

I expect this test to pass but in reality what happens is that because of the delayed init, the after runs before the example. If I change the Context to a trait I lose the delayed init functionality. Is this a bug or am I doing something wrong?

**当 Context 是 trait 时，此示例将抛出 NPE.我期望发生的是，由于延迟初始化，上下文的构造函数，这意味着 barReader.someBar 只会在 barReader 被注入后运行.

**Edited: This example will throw an NPE when the Context is a trait. What I expect to happen is that because of the delayed-init, the Context's constructor, which consequentially means the barReader.someBar will run only after the barReader has been injected.
