在 stb 测试任务期间运行设置/拆卸任务

Question

我尝试将 sbt 配置为在开始时运行设置任务，并在 myProject/test 命令结束时运行拆卸任务。

我的 build.sbt 在这里：

name := "ch-2"

version := "1.0"

libraryDependencies += "org.specs2" % "specs2_2.10" % "1.14" % "test"

lazy val common = (
  Project("common", file("common")).
    settings()
  )

lazy val subPro = (
  Project("sub", file("subA")).settings(
  ).dependsOn(common)
    settings(libraryDependencies += "org.specs2" % "specs2_2.10" % "1.14" % "test" )
  )

val startS = taskKey[Unit]("Start")
val stopS = taskKey[Unit]("Stop")
startS := { println("Running start")}
stopS := { println("Running stop")}

testOptions in Test in subPro += Tests.Setup { () => startS.value }
testOptions in Test in subPro += Tests.Cleanup { () => stopS.value }

实际的虚拟测试类在这里：

import org.specs2.mutable.Specification
/**
  * Created by jk on 26.3.2017.
  */
object FooSpec extends Specification {
  "The TEST method" should {
    "blaa blaa 1" in {
      println("test 1 running...")
      true
    }
    "blaa blaa 2" in {
      println("test 2 running...")
      true
    }
  }
}

当我为项目 sub 运行测试时，我得到以下输出：

> sub/test

为什么在编译完成之前停止任务运行以及如何修复它以便在所有测试用例运行后运行（尽管测试用例的结果）？

启动任务也应该在成功编译之后但在第一个测试用例之前运行。如何解决这些问题？

Answer 1

换成这样怎么样？

def startS(): Unit = { println("Running start")}
def stopS(): Unit = { println("Running stop")}

testOptions in Test in subPro += Tests.Setup { () => startS() }
testOptions in Test in subPro += Tests.Cleanup { () => stopS() }
