Code coverage using Jacoco - Multi module Maven

[Alessia Prete]

Hi,

I'm trying to get code coverage using Jacoco.

following this example:

https://github.com/SonarSource/sonar-examples/tree/master/projects/code-coverage/ut/ut-maven-multimodule-jacoco-runTests

Till now I haven't been able to make it works.

My project is multi-module Maven.

every module has src/main and src/test (with both UT and IT) 

Just to try I modified just  one module (api) pom the destination file, like described in the example:

 <plugin>

        <groupId>org.jacoco</groupId>
        <artifactId>jacoco-maven-plugin</artifactId>
        <configuration>
		  <!-- The destination file for the code coverage report has to be set to the same value
        	   in the parent pom and in each module pom. Then JaCoCo will add up information in
			   the same report, so that, it will give the cross-module code coverage. --> 
          <destFile>${project.basedir}/../target/jacoco-it.exec</destFile>
        </configuration>
        <executions>
          <execution>
            <id>post-test</id>
            <configuration>
              <skip>true</skip>
            </configuration>
          </execution>
        </executions>
      </plugin>


And modified parent's pom (plataform)  like this:
https://github.com/SonarSource/sonar-examples/blob/master/projects/code-coverage/ut/ut-maven-multimodule-jacoco-runTests/pom.xml



In the module I cannot see any jacoco-it.exec, and when I run sonar from parent I get:
 Project coverage is set to 0% as no JaCoCo execution data has been dumped: /home/solaria/workspace/platform/api/../target/jacoco-it.exec


What am I missing?


Thanks!

            <configuration>


              <skip>true</skip>


            </configuration>


          </execution>


        </executions>


      </plugin>






And modified parent's pom (plataform)  like this:

In the module I cannot see any jacoco-it.exec, and when I run sonar from parent I get:

I changed in the module's pom the jacoco goal, like this:

<executions>

          <execution>

            <goals>

              <goal>prepare-agent</goal>

            </goals>

          </execution>

        </executions>

Now it generates the jacoco.exec

When run sonar from parent dir, I can see:

[INFO] [14:08:56.663] Sensor JaCoCoSensor...

[INFO] [14:08:56.663] Analysing /home/solaria/workspace/platform/api/target/jacoco.exec

[INFO] [14:08:57.815] Sensor JaCoCoSensor done: 1152 ms

[INFO] [14:08:57.815] Sensor SurefireSensor..

But when I browse in sonar web, I get 0% integration  test coverage and 0 test unit.

suggestion?

thanks,

Ale

Hi Ale,

Could you highlight what you've changed because I cannot spot those changes?

If you run the sample project out of the box, does everything works fine?

Thank you

The difference with the sample project is that I don't have this:

parent

   ---> app 

         -->pom

    --> app-it

         -->pom

pom

but something like this:

platform

    -->api  

          -->src

          -->test(unit and integration)

    -->pom

pom

So basically I'm copying what is in app-it 's pom in api's pom.

Don't know if it's ok,..

Thanks

Hi,

From https://github.com/SonarSource/sonar-examples/blob/master/projects/code-coverage/ut/ut-maven-multimodule-jacoco-runTests/README.md : "This example demonstrates how to collect code coverage by integration tests, which located in a separate module." I suppose that this is not your case.

And modified parent's pom (plataform)  like this:






https://github.com/SonarSource/sonar-examples/blob/master/projects/code-coverage/ut/ut-maven-multimodule-jacoco-runTests/pom.xml















In the module I cannot see any jacoco-it.exec, and when I run sonar from parent I get:






 Project coverage is set to 0% as no JaCoCo execution data has been dumped: /home/solaria/workspace/platform/api/../target/jacoco-it.exec








What am I missing?


Thanks!

Hi Ale,

To help me understand your use case, when you say: "every module has src/main and src/test (with both UT and IT)", you mean:

• UT =  Unit Tests = tests that only test source code from the module itself
• IT = Integration Tests = tests that test source code from other modules

or

• UT and IT both test source code from the module itself

Thank you

Yes the sample project works perfectly.

Hi David,

yes basically in module's pom

instead of this :

<plugin>

        <groupId>org.jacoco</groupId>
        <artifactId>jacoco-maven-plugin</artifactId>



        <configuration>
		  <!-- The destination file for the code coverage report has to be set to the same value



        	   in the parent pom and in each module pom. Then JaCoCo will add up information in



			   the same report, so that, it will give the cross-module code coverage. --> 



          <destFile>${project.basedir}/../target/jacoco-it.exec</destFile>



        </configuration>
        <executions>
          <execution>



            <id>post-test</id>



            <configuration>



              <skip>true</skip>



            </configuration>



          </execution>
        </executions>
      </plugin>


I put:





<plugin>

            <groupId>org.jacoco</groupId>

            <artifactId>jacoco-maven-plugin</artifactId>
            <configuration>




          <!-- The destination file for the code coverage report has to be set to the same value

              <goal>prepare-agent</goal>



            </goals>
          </execution>



        </executions>

      </plugin>

and in parent's pom this:

  <sonar.jacoco.itReportPath>${project.basedir}/../target/jacoco-it.exec</sonar.jacoco.itReportPath>

whit:

<sonar.jacoco.reportPath>${project.basedir}/target/jacoco-it.exec</sonar.jacoco.reportPath>

I haven't try to run the sample project, I'll do it right now.

Thanks!

Hi Ale,

Could you highlight what you've changed because I cannot spot those changes?

If you run the sample project out of the box, does everything works fine?

Thank you

Anyway Evgeny is right..it's not my case.Sorry.

OK, so it cannot be achieved with your current project structure.

You need to externalize your ITs into specific modules, what seems to be a more logical structure from my point of view.

Then for :

• "Standard" modules, take app pom file as an example (basically you don't have anything to do)
• IT modules, take app-it pom file as an example
