Test cleanup hook not executed in scala play application

问题

Below is my Build.scala file

There is no error in test, but the cleanup hook is not executed after test
what is the issue?

import play.Project._
import sbt._
import sbt.Keys._

object AppBuild extends Build {
  val appName = "test"
  val appVersion = "1.0"

  val dependencies = Seq(
    "org.scalatest" % "scalatest_2.10" % "2.0.RC1"
  )

  val main = play.Project(
    appName, appVersion,
    dependencies,
    settings = Defaults.defaultSettings
  )
  .settings(
    scalaVersion := "2.10.1",
    testOptions in Test += Tests.Cleanup (
      () => println("Cleanup")
    )
  )
}

回答1:

testOptions in Test += Tests.Cleanup

does not work with forked test runs as mentioned in another Stackoverflow answer.

But there are workarounds:

Set fork to false

This is simple but may slow down your tests because they won't be executed in parallel.

sbt.Keys.fork in Test := false

Use the test framework

For example http://doc.scalatest.org/1.9.2/index.html#org.scalatest.BeforeAndAfterAll with the protected method afterAll()

Override the test task

My favorite.

test in Test ~= { testTask =>
  val result = testTask
  println("Cleanup")
  result
}
