Code coverage Arquilian and Jacoco

Here is the process of enabling code coverage analysis for integration tests by Arquilian and Jacoco. My assumeption is using Maven as the build tool. When using the Arquilian as integration testing framework for Java EE in container, the only choose for code coverage is jacoco. Arquilian has an extension for Jacoco. Our final setup for using Jacoco with arquilian on WAS and Glassfish are as folowing:

Jacoco can be used in 2 ways. When building the source by maven or when running the test in JUnit on IDE (Eclipse)

Maven configuration part

To configure the maven project and enable code coverage for all integration tests after building the codes by maven all you have to do is to add two dependencies and declare one plugin to one of the existing build profiles(or creating a new profile for Jacoco)

          <dependency>
                <groupId>org.jboss.arquillian.extension</groupId>
                <artifactId>arquillian-jacoco</artifactId>
                <version>1.0.0.Alpha6</version>
                <scope>test</scope>
             </dependency>
            <dependency>
                <groupId>org.jacoco</groupId>
                <artifactId>org.jacoco.core</artifactId>
                <version>0.6.4.201312101107</version>

<scope>test</scope>
            </dependency>

and the plugin part:

                 <plugin>
                        <groupId>org.jacoco</groupId>
                        <artifactId>jacoco-maven-plugin</artifactId>
                        <version>0.7.0.201403182114</version>
                        <executions>
                            <execution>
                                <goals>
                                    <goal>prepare-agent</goal>
                                </goals>
                            </execution>
                            <execution>
                                <id>report</id>
                                <phase>prepare-package</phase>
                                <goals>
                                    <goal>report</goal>
                                </goals>
                            </execution>
                        </executions>
                    </plugin>

When you want to run code coverage after build don't  forget to not skip test in maven:

<properties>

               <maven.test.skip>false</maven.test.skip>

          </properties>

Run in IDE

For using Jacoco in IDE you need EclEmma plugin for Eclipse. After installing the Plugin all the configs above  you can run code coverage by right click on the test method(class, package, project) and select Coverage As.
