为什么jacoco:cover会在Play 2.2中报告0次测试、0次失败、0次错误?

jacoco sbt playframework java

danclark1820 · 技术社区 · 12 年前

我可以使用 sbt test 。当我使用 sbt jacoco:cover 或 sbt jacoco:test 和 sbt jacoco:report 不管我得到什么 0 tests, 0 errors, 0 failures .Jacobo看到了我的测试文件,但没有看到测试

项目/Build.scala

import sbt._
import Keys._
import play.Project._
import de.johoop.jacoco4sbt._
import JacocoPlugin._

object ApplicationBuild extends Build {

   val appName         = "api"
   val appVersion      = "0.1-SNAPSHOT"

   lazy val s = playJavaSettings ++ Seq(jacoco.settings:_*)

   val appDependencies = Seq(
        "com.novocode" % "junit-interface" % "0.8" % "test"
   )

    val main = play.Project(appName, appVersion, appDependencies, settings = s).settings(

    **various resolvers**

   ).settings(
     jacoco.settings : _*
   ).settings( 
     testOptions in jacoco.Config += Tests.Argument("junitxml")    
   ).settings(
     testOptions in jacoco.Config += Tests.Setup( () => System.setProperty("config.file", "conf/application.conf") )
   ).settings(
     parallelExecution in jacoco.Config := false   
   )
}

项目/插件.sbt

// Use the Play sbt plugin for Play projects 
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.2.1")

// Use jacoco on sbt builds
libraryDependencies ++= Seq(
    "org.jacoco" % "org.jacoco.core" % "0.5.7.201204190339" artifacts(Artifact("org.jacoco.core", "jar", "jar")),
    "org.jacoco" % "org.jacoco.report" % "0.5.7.201204190339" artifacts(Artifact("org.jacoco.report", "jar", "jar"))
    )

 addSbtPlugin("de.johoop" % "jacoco4sbt" % "2.1.5")

我的测试正在进行测验目录

我正在使用:

重头戏2.2.1
Java 1.7.0_55
标准偏差0.13.2

我在网上为遇到同一问题的人找到的大多数答案都是 parallelExecution 未设置为 false 。当我检查时 sbt jacoco:parallelExecution 在 api 设置到的目录 假的 但当我跑的时候 sbt-jacoco:并行执行 在 project 或 test 设置到的目录 true .

我一加上它就开始工作了

.settings(
  Keys.fork in jacoco.Config := true    
)

到我的Build.scala文件。我希望我能解释更多这是如何工作的,但它仍然有点模糊。

谢谢大家的回答。它现在在本地运行得很好,但仍然在Jenkins中运行0个测试。

我刚刚用最新的Play2.3.1和jacoco4sbt 2.1.5对其进行了第一次测试,结果毫无问题。老实说,我自己都很惊讶,事情进展得如此顺利。

您不需要以下内容 项目/插件.sbt :

// Use jacoco on sbt builds
libraryDependencies ++= Seq(
    "org.jacoco" % "org.jacoco.core" % "0.5.7.201204190339" artifacts(Artifact("org.jacoco.core", "jar", "jar")),
    "org.jacoco" % "org.jacoco.report" % "0.5.7.201204190339" artifacts(Artifact("org.jacoco.report", "jar", "jar"))
)

为了测试它,我首先使用Typesafe Activator创建了Play应用程序 play-scala 样板

â  sandbox  activator new play-jacoco play-scala

Fetching the latest list of templates...

OK, application "play-jacoco" is being created using the "play-scala" template.

To run "play-jacoco" from the command line, "cd play-jacoco" then:
/Users/jacek/sandbox/play-jacoco/activator run

To run the test for "play-jacoco" from the command line, "cd play-jacoco" then:
/Users/jacek/sandbox/play-jacoco/activator test

To run the Activator UI for "play-jacoco" from the command line, "cd play-jacoco" then:
/Users/jacek/sandbox/play-jacoco/activator ui

â  sandbox  cd play-jacoco

然后我跑了 activator 进入shell并执行 test .

下列的 the Wiki on jacoco4sbt plugin site on GitHub ,然后我添加了 jacoco.settings 到 建筑.sbt 在顶级目录中。我还补充了 addSbtPlugin("de.johoop" % "jacoco4sbt" % "2.1.5") 到 项目/插件.sbt .

未进行其他更改。

我 reload 激活激活器外壳以加载更改。

您必须删除以下行。

testOptions in jacoco.Config += Tests.Argument("junitxml")

opiton不支持此选项。有关支持的选项列表,请检查 the documentation
