在机顶盒测试任务期间运行安装/拆卸任务

Question

我尝试将sbt配置为在开始运行一个安装任务，在myProject/test命令末尾配置一个下拉任务。

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
    }
  }
}

当我为项目子运行测试时，我得到以下输出：

> sub/test

为什么在编译完成之前就运行停止任务，以及如何修复它，以便在运行所有测试用例之后运行它(尽管有测试用例的结果)？

此外，开始任务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

不如就这样做吧？

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() }
