I'm trying to use JaCoCo agent for collecting FT code coverage of a web-site by adding "-javaagent..." to Jetty and running external Selenium tests (or, for example, manual testing).
At the end of testing I have results only for web-module, that was actually run in Jetty, but not for "core" modules (in the same project) being used in web-module. So, is there any ability to collect calls for all modules of the project?
Indeed, I now tried to start all project webservices (it has 5) with the same JaCoCo report destination (i.e. /tmp/jacoco-res.exec), append=true and ran:
mvn sonar:sonar -Dsonar.jacoco.itReportPath=/tmp/jacoco-res.exec
So, sonar now used the same JaCoCo report file for every module in project and sonar shows tests coverage both for jetty-run and core modules.
Is this approach applicable and coverage results correct?
I had a simular question that I posed on the Sonar User forum a couple of days ago.
In short, your approach is correct and was also proposed by a Sonar consultant (as can be seen on the post).
Perform a Sonar analyze on each Maven project.
For each analysis, reuse the report and pass your JaCoCo report (using -Dsonar.jacoco.itReportPath)
Sonar will retrieve from this JaCoCo report
the coverage data related to the Maven project being analyzed. (one of your core projects)
Thus, for each Maven project, you'll get the coverage by your integration tests.
Finally, to get the coverage of your webservice by your integration
tests, you will have to use the Views plugin:
http://www.sonarsource.com/products/plugins/governance/portfolio-management/
Create a view that is an aggregation of all the Maven
projects composing the webservice.
Run a Sonar analysis of one of its
Maven projects in order for Sonar to compute the view.
On the view dashboard, you'll be able to get the code coverage
of the webservice by your integration tests.

I am new to Jenkins, I have installed "Code Coverage API Plugin" in Jenkins, now want to test it.
I am trying to do steps from this page https://plugins.jenkins.io/code-coverage-api/.
But I did not understand where to put XML files from points 1 and 2.
Can anybody help me, please?
The tags present in the images are the plugins that will be added in the pom.xml of the application. By running mvn clean package cobertura will generate a report based on the formats provided, xml or html.
If the code is checked out to the job and after running "mvn clean package" cobertura report will be generated under project workspace target/site/cobertura
The xml path is provided to code coverage api to provide the graphical representation.
Jacaco is preferred for java versions >=8 whereas cobertura doesn't cover for java8 based functionalities.
Is it possible to create a code coverage Cobertura report and get it published on Sonar Dashboard for Websphere Commmerce Server (WCS) projects ? I understand that the pre-requisite is that the team should have written the Junit test cases but still wondering whether code coverage report is possible to generate ?
Under the assumptions that
a Websphere Commerce Server project is written in Java
the project contains unit tests that are executed during the build
a code coverage report is generated during the run of unit tests and pointed to during the analysis
Then the answer is yes.
I have a Jenkins build which build all my java/angularJS project. It launch testNG tests for the java part and karma tests for the javascript part. So I can generate one testNG report (for java) and one junit report (for karma test) in my Jenkins build. This is working very well.
Until now, I used cobertura to report the coverage of my java tests. But now I would like to add also a coverage report for my karma tests (generated by Istanbul with cobertura type). The problem is that, in Jenkins, I'm allowed to generate only one coverage report in a build (I can't add more that one 'publish cobertura coverage report' post build action). So how can I have these two coverage reports in a single Jenkins build?
There's a nice plugin called HTML Publisher Plugin. You can generate HTML coverage reports and publish as much reports as you want under different titles in one Jenkins project.
For example I generate html reports using karma+istanbul and then publish them to Jenkins.
On JUnit xml report files. You should import JUnit once enumerating all files probably from different directories but you can differentiate them with proper package names inside files.
If I'm right, you can't use, as a post build action, the same plug-in twice( note that I'm not really sure). I faced this problem when I worked as Jenkins plug-in developer for a company and the solution was to use a plug-in that make the same thing.
For example: for JUnit reports there is an official JUnit plugin and also XUnit. For my problem it was simple.
So, maybe you can find a plug-in that do the same thing as Cobertura or you can change the output format of the java coverage or karma coverage. For example, for java you can use EclEmma or Jacoco...
I am trying to get code coverage with Sonar and Jenkins. I see Jenkins' Sonar plugin successfully executes JUnit test cases and completes build successfully. But Sonar does not show Code Coverage results (always shows 0.0% as the code coverage) on the project. But Sonar does show "Unit test success".
I am using Maven with Jenkins and Sonar.
I get the below message in Jenkins logs while executing the Sonar plugin:
Project coverage is set to 0% as no JaCoCo execution data has been dumped: .../sonar/target/jacoco.exec
Can any one help me how to get correct code coverage on any Sonar project.
Just because Sonar invoked Surefire correctly (and you received the "Unit test success" message) doesn't mean that JaCoCo instrumented your code.
Try executing JaCoCo directly. You might find out why JaCoCo is failing directly:
mvn jacoco:prepare-agent test jacoco:report
JaCoCo will place jacoco.exec as well as its XML/HTML reports within target/jacoco. Or it will fail, and hopefully you'll have a better idea as to why.
One very common problem is that the JaCoCo javaagent will not run if you've changed the Surefire argLine at all, because jacoco:prepare-agent just sets the argLine property which in this scenario, is conveniently ignored. You can set prepare-agent's propertyName property to something else (like jacocoArgLine) and include that in your argLine config:
<argLine>-Xmx1024m ${jacocoArgLine}</argLine>
I read https://docs.sonarqube.org/display/PLUG/Code+Coverage+by+Unit+Tests+for+Java+Project and used cobertura as my code coverage plugin then I see code coverage displays for small projects. When I check for a big project in sonar I just see code coverage as - that means its empty. In logs I could find that Cobertura report was not found at /.../coverage.xml path.
coverage.xml was not generated due to OutOfMemeryError:heapspace. Since my project is such a big project when I set heap memory to 2GB and cobertura plugin memory to 1.5GB sonar gets code coverage displayed.
According to this blog post, you probably forget to set the sonar.binaries property in your project properties
Don’t forget sonar.binaries, otherwise, you might get something like « Project coverage is set to 0% since there is no directories with classes. » in your logs.
[...]
sonar.surefire.reportsPath=target/surefire-reports
sonar.jacoco.reportPath=target/jacoco.exec
sonar.binaries=target/classes
[...]
Your Sonar plug-in cannot find the report file generated by Jacoco.
In your pom(parent or child) look for the <destFile> tag under jacoco/prepare-agent execution. Change the name and the location to target/jacoco.exec and you are good to go!
Instead of using the Jenkins sonar plugin for running sonar, try to do it with maven, by executing the sonar goal. Usually this is easier then setting up an additional build step and tweaking all the paths till sonar finds all the relevant files.
In your case I guess it can read the junit/testng report, but can't find the jacoco results (jacoco.exec). Is the path sonar outputs(../sonar/target/jacoco.exec) correct?
I am running Sonar task through Ant, triggered by Jenkins in RHEL environment. I am successfully using Cobertura for Junit code coverage and Surefire for reporting. Sonar imports the Surefire reports fine.
However, now I am running Selenium tests using Ant in Jenkins. I would like to report code coverage and test results to Sonar. Apparently I need the JaCoCo plugin which analyses code coverage and reports tests. I presume like for unit tests, Jenkins does the job and Sonar only imports the reports into its own repository.
I am puzzled on how to actually do this. The web page http://www.sonarsource.org/measure-coverage-by-integration-tests-with-sonar-updated/ references to the JaCoCo page http://www.eclemma.org/jacoco/trunk/doc/ant.html. I am not sure what the steps are to be done. Do I need the coverage target? Should I only start the agent? Where in Ant do I start the agent? Do I need to dump stuff?
I really appreciate all the help I can get, thanks :)
Sonar 3.3 has a new feature for combine code coverage metrics generated by both unit tests and integration tests. This is done by using two properties to detail the two different report files generated by the jacoco too:
#Tells Sonar where the unit tests code coverage report is
sonar.jacoco.reportPath=reports/jacoco/jacoco-ut.exec
#Tells Sonar where the integration tests code coverage report is
sonar.jacoco.itReportPath=reports/jacoco/jacoco-it.exec
The Sonar examples project has an integration test example for ANT:
https://github.com/SonarSource/sonar-examples/tree/master/projects/code-coverage/it/ant/it-jacoco-ant
Unfortunately it doesn't give an example of running the actual tests, instead it just shows how to configure an ANT build to load data.
Finally the Sonar documentation has more details with links to the example projects.
