爲什麼jacoco：在Play 2.2中測試覆蓋報告0次測試，0次失敗，0次錯誤？

Question

我可以使用sbt test運行我的測試。當我運行測試使用sbt jacoco:cover或sbt jacoco:test和sbt jacoco:report但是我得到0 tests, 0 errors, 0 failures。 Jacoco看到我的測試文件，但沒有測試

項目/ 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 
    ) 
} 

項目/ plugins.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") 

我的測試下測試目錄

我正在使用：

• 播放2.2.1
• 的Java 1.7.0_55
• SBT 0.13.2

大多數我在網上找到了運行到同一問題的人的答案是的parallelExecution問題不被設置爲false。當我在api目錄中檢查sbt jacoco:parallelExecution時，它將設置爲false。但是當我在project或test目錄中運行sbt jacoco:parallelExecution時，它被設置爲true。

Answer 1

它開始工作，一旦我加入

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

我Build.scala文件。我希望我能解釋更多關於這是如何工作的，但它仍然有點模糊。

謝謝大家的答案。它現在在本地運行良好，但仍在Jenkins中運行0個測試。

Answer 2

我剛剛用最新的Play 2.3.1和jacoco4sbt 2.1.5進行了第一次測試，它沒有任何問題。老實說，我很驚訝自己有多順利。

您不需要按照項目/ plugins.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")) 
) 

爲了測試它，我首先創建使用play-scala模板使用類型安全的激活播放應用程序。

➜ 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 

➜ sandbox cd play-jacoco 

我然後跑activator進入外殼並執行test。

繼the Wiki on jacoco4sbt plugin site on GitHub，我再在頂層目錄添加到jacoco.settingsbuild.sbt。我還添加了addSbtPlugin("de.johoop" % "jacoco4sbt" % "2.1.5")到project/plugins.sbt。

沒有其他改變。

I reload編輯激活器外殼以加載更改。

Answer 3

您必須刪除以下行。

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

這是不支持的opiton。對於支持的選項列表檢查the documentation
