Hello,
I'm currently working on a multi-module maven project where we had some
integration tests running as regular unit tests (using surefire). This resulted
in a code coverage of about 10%.
After migrating the integration test (renaming them to *IT.java and executing
them using failsafe) I noticed that the integration test coverage rose to 16%
and my unit test coverage lowered to 9%.
I did read somewhere that jacoco doesn't support cross-module coverage, but it
seems like it does support it when running the tests as integration tests.
Is this behavior the be expected or should I be looking into a configuration
issue ?
The maven plugins are configured as follows:
<sonar.jacoco.reportPath>${project.basedir}/target/jacoco-unit.exec</sonar.jacoco.reportPath>
<sonar.jacoco.itReportPath>${project.basedir}/../target/jacoco-it.exec</sonar.jacoco.itReportPath>
