Question

我想做点什么：

class MySpec extends Specification with BeforeAfterExample {
  var testName
  var clientDir

  def before {
    testName = fragmentName.replaceAll(" ", "-")
    clientDir = new File(workspaceRoot, testName)
    clientDir.mkdirs()
  }

  def after {
    FileUtils.deleteDirectory(clientDir)
  }
}

Answer 1

这可能有用：

class MySpec extends Specification with BeforeAfterExample {
  var currentExample = 0
  var testName = ""
  var clientDir:File = null

  def before {
    testName = is.examples(currentExample).desc.toString.replaceAll(" ", "-")
    clientDir = new File(workspaceRoot, testName)
    clientDir.mkdirs()
  }

  def after {
    FileUtils.deleteDirectory(clientDir)
    currentExample += 1    
  }
}

我不认为你可以在之前和之后的方法中获得更多的上下文，而不会像这样做一些hacky。

Answer 2

您可以使用specs2 ExampleFactory

执行您想要的操作

import org.specs2._
import specification._

class TestSpec extends Specification { def is =
  "test" ! {
    ok
  }
  case class BeforeAfterExample(e: Example) extends BeforeAfter {
    def before = println("before "+e.desc)
    def after  = println("after "+e.desc)
  }
  override def exampleFactory = new ExampleFactory {
    def newExample(e: Example) = {
      val context = BeforeAfterExample(e)
      e.copy(body = () => context(e.body()))
    }
  }
}

API的这一部分最近才刚刚开放，所以它现在仅在1.15-SNAPSHOT中可用（你可以通过直接在{{1}开头的软件包中创建工厂来解决这个限制，使用更新的specs2版本}）。

Answer 3

有点hacky，但这对我有用：

/**
 * Returns the name of the currently executing example
 */
def getCurrentExampleName(spec: Specification): String = {

  val stack = new Exception().getStackTrace
  val specLinesUpStack = for (
    line <- stack
      if line.getClassName.startsWith(spec.getClass.getName))
        yield line.getLineNumber

  spec.is.examples
    .find(e => specLinesUpStack.contains(e.location.lineNumber))
    .get
    .desc.toString()
}

如何在方法之前和之后访问Specs2中的测试/示例/片段名称？
