I’m using JaCoCo, Arquillian and rest-assured to test my RESTFul API. The problem is that I’m getting a 0% code coverage within my JaCoCo report. I’m using a maven profile for test cases, getting a wildfly instance, deploying it on JVM, deploying my API and then running the tests.
I’ve made some researches and reach the point where I know that JaCoCo must be running on same JVM where the .war file is running (What is my case).
As JaCoCo is on the same JVM, I thought the coverage wouldn’t suffer any changes, but it brings me 0%.
Can anyone help me with this?
Follows my maven profile on pom.xml:

Answer
I’ve had to configure the JaCoCo agent when Arquillian started the container. Actually, my jacoco plugin becomes:
pom.xml
JavaScript
<plugin> <groupId>org.jacoco</groupId> <artifactId>jacoco-maven-plugin</artifactId> <version>${plugin.jacoco.version}</version> <executions> <execution> <id>jacoco-prepare</id> <phase>validate</phase> <goals> <goal>prepare-agent-integration</goal> </goals> <configuration> <propertyName>jacoco.agent</propertyName> </configuration> </execution> <execution> <id>jacoco-report</id> <phase>post-integration-test</phase> <goals> <goal>report-integration</goal> </goals> </execution> </executions></plugin>In the arquillian.xml arguments, add the ${jacoco.agent} variable at the end of “javaVmArguments” property. Like this:
JavaScript
<property name="javaVmArguments">-Djboss.socket.binding.port-offset=10000 -Xms512m -Xmx1024m -XX:MaxPermSize=512m ${arquillian.debug} ${jacoco.agent}</property>
