Jacoco extension does not work with gradle

[ivan.macalak]

Hallo,

I'd like to measure a code coverage during Arquillian integration tests. I use gradle to build my application and execute Arquillian tests.

I have jacoco and arquillian-jacoco:1.0.0.Alpha6 inclued on test runtime classpath. My arquillian.xml looks like following:

<?xml version="1.0"?>

<arquillian xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            xmlns="http://jboss.org/arquillian-1.0"

            xsi:schemaLocation="http://jboss.org/arquillian-1.0 http://jboss.org/schema/arquillian/arquillian-1.0.xsd">

  <defaultProtocol type="Servlet 3.0"/>

    <container qualifier="jbossas_managed" default="true">

      <configuration>

         <property name="jbossHome">../../runtime/jboss-eap-6.3.0.Alpha/</property>

         <property name="javaVmArguments">-Dproject.phase=integration -Xmx768m -XX:MaxPermSize=256m</property>

         <property name="managementPort">10999</property>

         <property name="serverConfig">standalone-full.xml</property>

         <property name="allowConnectingToRunningServer">true</property>

         <property name="outputToConsole">true</property>

      </configuration>

   </container>

   <extension qualifier="jacoco">

    <property name="includes">my-package.*</property>

  </extension>

</arquillian>

Should this setup work, or is the jacoco extension integrated with maven only?

How can I detect, if jacoco is active during test execution?

Thanks,

Ivan.

Hi there,

only declaring the extension and dependency isn't enough.

First you need to start jacoco agent, in maven its done  via plugin with goal prepare-agent

and later you need to generate reports based on jacoco inspection you started in previous step(jacoco.exec file), in maven its also done at plugin level.

with gradle you may take a look at: http://www.gradle.org/docs/current/userguide/jacoco_plugin.html

i hope it helps

Hi Rafael,

thanks for the quick answer.

My generated jacoco.exec file does not contain coverage info of my EJBs and other components deployed as part of Arquillian tests.

I'm using the ZipImporter to build ear archive to avoid redeploying for each test suite.

It seems that coverage of ear is not currently supported by Alpha6 version of jacoco extension. (https://issues.jboss.org/browse/ARQ-1387)

Is there any plan to add such support?

Ivan.

It wasn't supported in <= Alpha5. Alpha6 should support it.

Did it help Ivan Macalak? If so we can close this thread.

Hi, I'm still not able to get it to work. The jacoco.exec generated by gradle plugin does not contain coverage info for classes executed as part of arquillian test run.

It seems, only maven is supported. Or can you provide some working example with gradle?

This thread is already old, but just in case, we managed to make Jacoco work with Arquillian and Gradle with the following configuration:

On root project:

subprojects {
  apply plugin: 'java'
  apply plugin: 'jacoco'
  jacoco {
    toolVersion = '0.7.4.201502262128'
    reportsDir = file("$buildDir/jacoco")
  }
}

On the sub-project to be tested with Arquillian:

dependencies {
  testCompile 'YOUR_ARQUILLIAN_ADAPTER'
  testCompile 'org.jboss.arquillian.junit:arquillian-junit-container:1.1.5.Final'
  testCompile 'org.jboss.arquillian.extension:arquillian-jacoco:1.0.0.Alpha7'
}

// Important: add the Jacoco libs on the test classpath (required for the Jacoco Arquillian extension to work).
sourceSets {
    test.runtimeClasspath += configurations.jacocoAnt
}

And that's it.
