Question

如何从specs2中的Around块中的单独类的函数运行匹配器？

示例（使用Play框架）：

class Spec extends Specification {
  "the application" should {
    "do something" in new WithBrowser { // <-- 1. because of this around block
      val runner = new Runner
      runner.check(browser)
    }
  }
}

class Runner extends MustMatchers {
  def check(browser: TestBrowser) = {
    browser.pageSource must contain("some text that isn't there") // <-- 2. this won't fail
  }
}

我在Around scaladoc中读到它没有与不会抛出FailureExceptions的匹配器一起工作。这是否意味着我必须亲自检查所有匹配器？我怎样才能让我的匹配器失败？

通过扩展MustMatchers，您遗憾地设法避免引入具有以下文档的所有重要MustThrownExpectations特征：

/**
* This trait provides implicit definitions to transform any value into a 
* MustExpectable, throwing exceptions when a match fails
*/

如果您从mutable.Specification一直遵循所有Specs2特征，那么有一个特征MustThrownMatchers，它会以“正确的方式”为您的用例失败;即：

class ThrowingRunner extends MustThrownMatchers {
  def check(browser: TestBrowser) = {
    browser.pageSource must contain("some text that isn't there")
  }
}
