scala - 如果测试失败，如何配置 ScalaTest 以中止套件？

Question

我将 ScalaTest 2.1.4 与 SBT 0.13.5 一起使用。我有一些长时间运行的测试套件，如果单个测试失败(多 JVM Akka 测试)，它们可能需要很长时间才能完成。如果其中任何一个失败，我希望整个套件中止，否则套件可能需要很长时间才能完成，尤其是在我们的 CI 服务器上。

如果套件中的任何测试失败，我如何配置 ScalaTest 以中止套件？

如果您只需要取消与失败测试相同的规范/套件/测试中的测试，您可以使用 scalatest 中的 CancelAfterFailure 混合。如果你想全局取消它们，这里是示例:

import org.scalatest._


object CancelGloballyAfterFailure {
  @volatile var cancelRemaining = false
}

trait CancelGloballyAfterFailure extends SuiteMixin { this: Suite =>
  import CancelGloballyAfterFailure._

  abstract override def withFixture(test: NoArgTest): Outcome = {
    if (cancelRemaining)
      Canceled("Canceled by CancelGloballyAfterFailure because a test failed previously")
    else
      super.withFixture(test) match {
        case failed: Failed =>
          cancelRemaining = true
          failed
        case outcome => outcome
      }
  }

  final def newInstance: Suite with OneInstancePerTest = throw new UnsupportedOperationException
}

class Suite1 extends FlatSpec with CancelGloballyAfterFailure {

  "Suite1" should "fail in first test" in {
    println("Suite1 First Test!")
    assert(false)
  }

  it should "skip second test" in {
    println("Suite1 Second Test!")
  }

}

class Suite2 extends FlatSpec with CancelGloballyAfterFailure {

  "Suite2" should "skip first test" in {
    println("Suite2 First Test!")
  }

  it should "skip second test" in {
    println("Suite2 Second Test!")
  }

}
