    For java there are different plugins/properties that must be included in the pom.xml to execute the tests and record the coverage

    Surefire (Unit tests)

    This one is used to execute the unit tests, various config are available depending of the project need (https://maven.apache.org/surefire/maven-surefire-plugin/index.html)

                                </executions>
</plugin>

    Note that for the integration tests, it could more complex than the following Jacoco plugin usage, if it's a remote server or anything else the jacoco agent must be provided to the running JVM to do the coverage recording (https://www.eclemma.org/jacoco/trunk/doc/agent.html)
