Running integration tests with Cobertura Maven plugin

Question

I am having trouble getting the Cobertura plugin to run integration tests in Maven. The closest answer to this question I have found is http://jira.codehaus.org/browse/MCOBERTURA-86. However, the issue remains an open bug. I tried the configuration suggested by Stevo on 03/Apr/09, it didn't work.

My POM

<reporting>
    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>cobertura-maven-plugin</artifactId>
            <version>2.3-SNAPSHOT</version>
            <reportSets>
            <reportSet>
                <reports>
                    <report>cobertura-integration</report>
                </reports>
            </reportSet>
            </reportSets>               
        </plugin>   
    </plugins>
</reporting>

which is by the way exactly the same as the configuration fragment provided by Stevo.

From my opinion, the cobertura maven plugin has two big disadvantages. It has no report only goal, all unit tests will run beside surefire again. It creates the code coverage for unit tests only .

I am using the JaCoCo maven plugin now. JaCoCo reuses the surefire and/or failsafe reports to create a code coverage from unit and/or integration test. Furthermore JaCoCo has a good Jenkins integration. Here is an example where JaCoCo uses surefire unit tests and failsafe integration tests.

    <build>
    <plugins>
        <!-- Unit tests -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.16</version>
        </plugin>

        <!-- Integration tests -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-failsafe-plugin</artifactId>
            <version>2.16</version>
            <executions>
                <execution>
                    <phase>integration-test</phase>
                    <goals>
                        <goal>integration-test</goal>
                        <goal>verify</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

        <!--
            The JaCoCo plugin generates a report about the test coverage. In contrast to the cobertura plugin
            JaCoCo can be configured to generate code coverage for integration tests. Another advantage of JaCoCo
            is that it reports only, cobertura executes all unit tests again (beside the surefire plugin).
