Question

在我们的项目中，我们将Scala Specs2与Selenium一起使用。我试图实施故障屏幕截图机制＆＃34; in a classic way (link)＆＃34;对于我的测试，使用JUnit注释，但是，该规则根本没有调用测试失败。

测试结构如下：

class Tests extends SpecificationWithJUnit{

      trait Context extends LotsOfStuff {
        @Rule
        val screenshotOnFailRule = new ScreenshotOnFailRule(driver)
      }

      "test to verify stuff that will fail" should {
        "this test FAILS" in new Context {
         ...
      }
}

ScreenshotOnFailRule如下所示：

class ScreenshotOnFailRule (webDriver: WebDriver) extends TestWatcher {

  override def failed(er:Throwable, des:Description) {
    val scrFile = webDriver.asInstanceOf[TakesScreenshot].getScreenshotAs(OutputType.FILE)
    FileUtils.copyFile(scrFile, new File(s"/tmp/automation_screenshot${Platform.currentTime}.png"))
  }
}

据我所知，它现在可能无法正常工作，因为测试没有使用@Test注释进行注释。是否可以使用JUnit @Rule注释来注释Specs2测试？

根据this question，似乎不支持JUnit规则。但您可以尝试使用AroundExample特征：

import org.specs2.execute.{AsResult, Result}
import org.specs2.mutable._
import org.specs2.specification.AroundExample

class ExampleSpec extends Specification with AroundExample {

  // execute tests in sequential order
  sequential

  "The 'Hello world' string" should {
    "contain 11 characters" in  {
      "Hello world" must have size (10)
    }

   // more tests..
  }

  override protected def around[T](t: => T)(implicit ev: AsResult[T]): Result = {
    try {
      AsResult.effectively(t)
    } catch {
      case e: Throwable => {
        // take screenshot here
        throw e
      }
    }
  }
}

如何在Scala Specs2测试中使用JUnit的@Rule注释？
