[Java 2.1.x] Sonar coverage

[Peter Önneby]

Hi,

Has anyone managed to get Sonar to analyse the coverage data (jacoco.exec)? 

I get a NullpointerException when using Sonar runner and sonar.jacoco.reportPath=target/scala-2.10/jacoco/jacoco.exec;

Exception in thread "main" org.sonar.runner.RunnerException: java.lang.NullPointerException

        at org.sonar.runner.Runner.delegateExecution(Runner.java:288)

        at org.sonar.runner.Runner.execute(Runner.java:151)

        at org.sonar.runner.Main.execute(Main.java:84)

        at org.sonar.runner.Main.main(Main.java:56)

Caused by: java.lang.NullPointerException

        at org.sonar.plugins.jacoco.ExecutionDataVisitor.visitClassExecution(ExecutionDataVisitor.java:48)

        at org.jacoco.core.data.ExecutionDataReader.read(ExecutionDataReader.java:85)

        at org.sonar.plugins.jacoco.AbstractAnalyzer.readExecutionData(AbstractAnalyzer.java:118)

...

Plugins.scala

addSbtPlugin("play" % "sbt-plugin" % "2.1.1")

addSbtPlugin("de.johoop" % "jacoco4sbt" % "1.2.4")

My Build.scala:

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


  val main = play.Project(appName, appVersion, appDependencies, settings = s).settings(
    // Add your own project settings here      
    parallelExecution     in jacoco.Config := false,
    jacoco.reportFormats  in jacoco.Config := Seq(XMLReport("utf-8"), HTMLReport("utf-8")),
    jacoco.excludes       in jacoco.Config := Seq("*anon*", "views*", "*Routes*", "controllers*routes*", "controllers*Reverse*", "controllers*javascript*", "controller*ref*")
  )

Does anyone have a working setup?

Thanks

Peter

Hi Peter,

Have you tested to make sure you have Jacoco working in a standalone fashion yet?  If not, you can use this project for sample code:

Hi Philip,

Thanks for the link, I forgot to say I do already get the HTML report OK.
It's as if there is something missing in the generated jacoco.exec.
Any other ideas before I start debugging the sonar sources?

Hey Peter,

Have you managed to get SonarQube to work with Play Jacoco?

I'm struggling with the same issue

Thank Łukasz

I'm also trying to get coverage into Sonar, apparently it is possible using SCCT [1] because it will output a cobertura file [2].

If someone knows how to do that using a recent version of Play, let me know how you did it. Someone made a tutorial here [3].

Hey Lukasz

I've not tried since I last posted but I keep an eye on the jacoco4sbt plugin in case there are any developments.

I noticed you are too :). I'm guessing from reading your post that the latest version of jacoco4sbt still doesn't generate the coverage for Play apps?

Thanks,

Peter

Hey, 

I almost managed to get everything work.

plugins.sbt:

resolvers += "Sonatype snapshots" at "http://oss.sonatype.org/content/repositories/snapshots/"

libraryDependencies ++= Seq(

  "org.jacoco" % "org.jacoco.core" % "0.5.9.201207300726" artifacts(Artifact("org.jacoco.core", "jar", "jar")),

  "org.jacoco" % "org.jacoco.report" % "0.5.9.201207300726" artifacts(Artifact("org.jacoco.report", "jar", "jar"))

)

// Add Jacoco plugin library

addSbtPlugin("de.johoop" % "jacoco4sbt" % "2.1.1")

qa.sbt in project root:

import sbt._

import Keys._

import play.Project._

import de.johoop.jacoco4sbt._

import de.johoop.jacoco4sbt.JacocoPlugin._

jacoco.settings

// Add the 'jacoco:cover' command to Play console. 

// Output file: target/jacoco/html/index.html

parallelExecution      in jacoco.Config := false

jacoco.outputDirectory in jacoco.Config := file("target/jacoco")

jacoco.reportFormats   in jacoco.Config := Seq(XMLReport("utf-8"), HTMLReport("utf-8"))

jacoco.excludes        in jacoco.Config := Seq("my.package.Global*", "*Global*", "*views*", "my.package*", "securesocial", "*Routes*", "*controllers*routes*", "*controllers*Reverse*", "*controllers*javascript*", "*controller*ref*")

Note that the "my.package.Global*" works only on my linux machine for me but not on win7, therefore I included "*Global*" as well.

Then my Sonar runner properties:

# required metadata

sonar.projectKey=myproject:key

sonar.projectName=myproject

sonar.projectVersion=1.0

 

# optional description

sonar.projectDescription=desc

#the sources of the application

sonar.sources=app

#the test sources

sonar.tests=test

#the compiled classes

sonar.binaries=target/scala-2.10/classes

 

# The value of the property must be the key of the language.

sonar.language=java

sonar.java.source=1.7

sonar.java.target=1.7

 

# Encoding of the source code

sonar.sourceEncoding=UTF-8

sonar.host.url=http://mydomain:9009

sonar.jdbc.url=jdbc:postgresql://mydomain/sonar

sonar.jdbc.username=sonar

sonar.jdbc.password=insertsomethingcreative

#tell sonar to reuse the reports

sonar.dynamicAnalysis=reuseReports

#where to find the junit report xmls

sonar.junit.reportsPath=target/test-reports

#code coverage plugin

sonar.java.coveragePlugin=jacoco

#jacoco exec path

sonar.jacoco.reportPath=target/jacoco/jacoco.exec

A remaining issue here is that play exports the junit reports in the format TestClassName.xml, whereas for some reason the report only gets picked up when prefixed with "TEST-".

The other issue is that while there's an elapsed time for the whole suite, there's always 0 (zero) inserted for the separate test cases.

So my question would be:

1, how to rename the report xml files?

2, is there a way to get the execution time for each test case?

thanks,

Balázs

Hi

I try to configure jacoco with your recommendation and I still have

Caused by: java.lang.NullPointerException
    at org.sonar.plugins.jacoco.ExecutionDataVisitor.visitClassExecution(ExecutionDataVisitor.java:48)

Can you take a look on my configuration :

        parallelExecution         in jacoco.Config := false,

        jacoco.outputDirectory    in jacoco.Config := file("target/jacoco"),
        jacoco.reportFormats      in jacoco.Config := Seq(XMLReport("utf-8"), HTMLReport("utf-8")),  
        jacoco.excludes           in jacoco.Config := Seq("views*", "*Routes*", "controllers*routes*", "controllers*Reverse*", "controllers*javascript*", "controller*ref*"),

    <!-- Jacoco configuration -->
    <property name="sonar.dynamicAnalysis" value="reuseReports" />
    <property name="sonar.junit.reportsPath" value="../target/test-reports" />
    <property name="sonar.java.coveragePlugin" value="jacoco" />    
    <property name="sonar.jacoco.reportPath" value="../target/jacoco/jacoco.exec" />
Did I miss something?

A Sonar plugin has been released for scoverage : https://github.com/scoverage/sonar-scoverage-plugin

You can use it if you want to include statement level coverage / block level coverage in your Sonar dashboard.
