Question

我有这样的设置：

class PriceAwareSpec extends Specification  {

 sequential

 running(FakeApplication()) {

 val price = "CHF 50.00"
 val priceAsHtml: Html = Html(price)

 val context: Context = ContextAccessUtil.getContext
 val stateAccess = ServiceFactoryUtil.getService(context, classOf[StateAccess])

 "price aware template" should {

   "per default" in {

    stateAccess.store(StateKeys.HIDE_NETTO_KEY, java.lang.Boolean.FALSE)

     "show netto" in {
       val html = views.html.price.priceAware(priceAsHtml, true)(request)
       contentAsString(html) must contain(price)
     }

     "show brutto" in {
       val html = views.html.price.priceAware(priceAsHtml, false)(request)
       contentAsString(html) must contain(price)
     }
   }
 }
}

致电

ContextAccessUtil.getContext

可以使用

访问播放缓存

play.cache.Cache.get("foo")

哪个尝试从当前应用程序获取信息（= FakeApplication（）？）

这会导致NullPointerException：

[error]       NullPointerException: null (Cache.scala:-1)
[error] play.api.cache.Cache$.get(Cache.scala:57)
[error] play.api.cache.Cache.get(Cache.scala)
[error] play.cache.Cache.get(Cache.java:16)

这表明没有应用程序存在....？！

我的设置有问题吗？

如Play 2.0 wiki所述，必须为每个例子创建上下文：

"Computer model" should {

  "be retrieved by id" in new WithApplication {
    val Some(macintosh) = Computer.findById(21)

    macintosh.name must equalTo("Macintosh")
    macintosh.introduced must beSome.which(dateIs(_, "1984-01-24"))  
 }

 // or, if you want to be more specific about your configuration
 "be retrieved by id" in new 
    WithApplication(FakeApplication(additionalConfiguration = inMemoryDatabase())) {
    ...
 }

}

这确保每个示例都在FakeApplication的上下文中执行。另一方面，您在代码中所做的是围绕创建示例并使用FakeApplication，这对其执行没有影响。请注意，Play 2.0的下一个版本应该有an even easier version用于您要执行的操作：

class MySpec extends Specification with ApplicationExample {

  // only override if necessary
  implicit override val app = 
    FakeApplication(additionalConfiguration = Map("foo" -> "bar"))

  "something" should {
    ...
  }

}

使用Fakeapplication的规范测试失败，可以访问play.Cache - ＆gt;没有申请
