在stb测试任务期间运行setup/teardown任务

Question

我尝试配置sbt以在开始时运行安装任务，并在myProject/test命令结束时执行拆卸任务。

我build.sbt是在这里：

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 } 

实际假人测试类是在这里：

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 
    } 
    } 
} 

当我运行项目的子测试，我得到以下的输出：

> sub/test 
Running stop

为什么即使在编译完成之前停止任务仍在运行，以及如何修复它以便在所有测试用例之后运行运行（尽管测试用例的结果）？

此外，启动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

如何做到这一点呢？

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() }
