Question

我有一组测试套件也会增长，我需要运行一个testcleanup任务，该任务应该在所有测试完成执行之后和测试进程退出之前运行一次。这类似于.NET AssebmlyCleanup，但我无法在Scala / Scalatest世界中找到相同的东西，而不必自定义代码，是吗？

我一直在考虑如何处理此问题，一种方法是在test中覆盖testOnly和build.sbt位。因此，假设我们在src/test/scala下面有两个套件：

class Suite1 extends FlatSpec{
  "Test1 in Suite1" should "succeed" in{
    succeed
  }
}

和

class Suite2 extends FlatSpec{
  "Test1 in Suite2" should "succeed" in{
    succeed
  }
}

现在让我们在/project/文件夹下添加一个CleanUp.scala对象，我们的清理工作将在其中：

object CleanUp{
  def cleanUp:Unit = println("Cleaning up after all suites are completed.")
}

这是一个最小的例子，实际上你可能有任何需要的复杂清理。现在在build.sbt我们添加以下内容：

(test in Test) := {
  val testsResult = (test in Test).value
  CleanUp.cleanUp
  testsResult
}

(testOnly in Test) := {
  (testOnly in Test).evaluated
  CleanUp.cleanUp
}

这会覆盖test和testOnly任务的默认行为，因此在执行所有套件（或用户套件指定的所有套件）之后将应用清理。

例如，这是我对新testOnly：

的sbt控制台检查

[IJ]sbt:AfterAllTests> testOnly Suite1
[info] Suite1:
[info] Test1 in Suite1
[info] - should succeed
[info] Run completed in 150 milliseconds.
[info] Total number of tests run: 1
[info] Suites: completed 1, aborted 0
[info] Tests: succeeded 1, failed 0, canceled 0, ignored 0, pending 0
[info] All tests passed.
Cleaning up after all suites are completed.
[success] Total time: 0 s, completed Dec 2, 2017 12:19:48 AM
[IJ]sbt:AfterAllTests>

这是检查新的test：

[IJ]sbt:AfterAllTests> test
[info] Suite2:
[info] Test1 in Suite2
[info] - should succeed
[info] Suite1:
[info] Test1 in Suite1
[info] - should succeed
[info] Run completed in 164 milliseconds.
[info] Total number of tests run: 2
[info] Suites: completed 2, aborted 0
[info] Tests: succeeded 2, failed 0, canceled 0, ignored 0, pending 0
[info] All tests passed.
Cleaning up after all suites are completed.
[success] Total time: 2 s, completed Dec 2, 2017 12:28:25 AM
[IJ]sbt:AfterAllTests>

如您所见，可以调用cleanup。希望这会有所帮助。

是否有scalaTest方法或属性可用于在所有套件中的所有测试之后运行一次
