unable to get IT code coverage using jacoco

[sripri...@gmail.com]

Hi Team,

We are not able to get IT code coverage using Jacoco.

IT coverage is shown as 0.0% in sonar dashboard.

As a first step we have generated jacoco-it.exec file and executed the below command to get the coverage on sonar dashboard.

mvn -Dsonar.jacoco.itReportPath="E:\BuildAgent\work\b8f0a63c1c75b440\services\branches\phase_1_iteration_3\target\jacoco-it.exec" sonar:sonar -Dsonar.dynamicAnalysis=reuseReports


Please note that it is a multi module project and we need IT coverage for a particular module.

Kindly help us in resolving this issue and let me know if any further information is needed.

Thanks,
Sri Priyanka

I am attaching the pom.xml that we have used to generate jacoco-it.exec and also the index.html file generated after executing the above command(sonar step).

Have you performed the checks described in the FAQ? What are your
observations?

http://www.eclemma.org/jacoco/trunk/doc/faq.html


Q: Why does a class show as not covered although it has been executed?

A: First make sure execution data has been collected. For this select
the Sessions link on the top right corner of the HTML report and check
whether the class in question is listed. If it is listed but not linked
the class at execution time is a different class file. Make sure you're
using the exact same class file at runtime as for report generation.
Note that some tools (e.g. EJB containers, mocking frameworks) might
modify your class files at runtime. Please see the chapter about class
ids for a detailed discussion.


Best regards,

Hi Marc,

Thanks for the explaination.

When i see the sessions link in the HTML report generated it lists down only the integration tests classes with the ids that got executed,but i didn't get the code coverage for the integration tests.

Coming to in detailed information of integration tests these will be make use of the JBoss container for execution and in built h2 database for data setup for execution of integration tests.

Thanks,
Sravan Kumar Indupuri

Hi Sravan,

you need to make sure that you configure the JaCoCo agent for the JVM
where your classes under test are actually executed, in your case the
JBoss container.

Hi Marc,

I have configured the JaCoCo agent for the JVM where your classes under test are actually executed.

PFA Plugins_Services and Plugins_Jacoco for the plugins I have configured in the pom.xml for the maven sure fire, maven fail safe and jacoco maven plugin.

 

I have configured the jacoco agent pointing during run time before execution of integration tests in the maven fail safe plugin in the following way:

 <configuration>
       <!-- Sets the VM argument line used when integration tests are run. -->
       <argLine>${failsafeArgLine}</argLine>
  </configuration>

But as the reports generated for Junit test cases as well as integration tests I am able to figure out a small difference:

1. For the HTML report generated for the Junit test cases I am able to see the java classes which were executed while execution of java test classes but not able to see the Test java classes.

2.For the HTML report generated for the Integration test cases I am not able to see the java classes which were executed while execution of java test classes but able to see the Test java classes.

Please let me know your suggestions.

Thanks,

Sravan Kumar

Hi Marc,

As suggested i have tested configuring the VM Parameter for MAVEN_OPTS as 

setx MAVEN_OPTS "-Xmx512m -XX:MaxPermSize=128m -verbose" and ran the build using mvn clean install -Parq-jboss-remote where arq-jboss-remote is the profile configured for running intergration test cases(Arquillian test cases).

I am able to see the see the classes loaded from jdk, apaven maven and test classes (Junits and integration tests) required for the build , but not able to see the tested classes for JUnit as well as Integration tests.

Thanks,

Sravan Kumar
