Running integration tests with Cobertura Maven plugin - maven-2

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.

Answer 1

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).
-->
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.6.4.201312101107</version>
<executions>
<execution>
<id>jacoco-prepare-agent</id>
<goals>
<goal>prepare-agent</goal>
</goals>
</execution>
<execution>
<id>jacoco-prepare-agent-integration</id>
<goals>
<goal>prepare-agent-integration</goal>
</goals>
</execution>
<execution>
<id>jacoco-report</id>
<goals>
<goal>report</goal>
</goals>
</execution>
<execution>
<id>jacoco-integration</id>
<goals>
<goal>report-integration</goal>
</goals>
</execution>
<execution>
<id>jacoco-check</id>
<goals>
<goal>check</goal>
</goals>
<configuration>
<rules />
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>

Answer 2

Try to configure a execution phase for that plugin like
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>cobertura-maven-plugin</artifactId>
<version>2.5.1</version>
<configuration>
<formats>
<format>xml</format>
</formats>
</configuration>
<executions>
<execution>
<id>cobertura-check</id>
<phase>verify</phase>
<goals>
<goal>cobertura</goal>
</goals>
</execution>
</executions>
</plugin>
That way it works like a charm for me.

Answer 3

After some research found a working config listed from http://jira.codehaus.org/browse/MCOBERTURA-86
Make sure to invoke this with
mvn clean deploy -PbuildWithIntegrationTestCoverage
<profile>
<!-- Build with IntegrationTestcoverage => instrument classes with cobertura before integrationtests starts. -->
<id>buildWithIntegrationTestCoverage</id>
<activation>
<property>
<name>buildWithIntegrationTestCoverage</name>
<value>true</value>
</property>
</activation>
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>cobertura-maven-plugin</artifactId>
<version>2.5.2</version>
<executions>
<execution>
<id>instrument-classes</id>
<phase>package</phase>
<goals>
<goal>instrument</goal>
</goals>
</execution>
</executions>
</plugin>
<!-- Add cobertura as dependency to the jetty-plugin (required for instrumented classes) -->
<plugin>
<groupId>org.mortbay.jetty</groupId>
<artifactId>maven-jetty-plugin</artifactId>
<dependencies>
<dependency>
<groupId>org.codehaus.mojo</groupId>
<artifactId>cobertura-maven-plugin</artifactId>
<version>2.5.2</version>
<type>jar</type>
</dependency>
</dependencies>
</plugin>
</plugins>
</build>
</profile>

Answer 4

For anyone stumbling on this question through Google - cobertura-maven-plugin started supporting integration tests in version 2.7, which was published in 2015.
Quoting their website:
Up to version 2.6 there were only one report available: cobertura,
which gave you a coverage report for your unit tests. Since there was
only one, you didn't have to configure it in any way.
Starting with version 2.7 a new report was added:
cobertura-integration-test, which gives you a coverage report for your
integration tests. [..]
Both reports are enabled by default. If you want the old behaviour
with only a coverage report for your unit tests, you need to configure
the plugin ...
If you, like I did, run cobertura report using mvn cobertura:cobertura, you'll need to do mvn cobertura:cobertura-integration-test to get integration tests as well. You can check the details from its manual page.

Answer 5

I found that using the maven-antrun-plugin for multi-module projects including integration and UI tests is the best solution. I used this post to get the Ant goals down and went from there. We now have code coverage reports per module and merged one containing coverage from all tests.

Answer 6

I got the integration tests working with Maven 3.0.3 and cobertura-maven-plugin 2.5.1 by configuring the maven-failsafe-plugin to run during the test phase:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
<version>2.12</version>
<executions>
<execution>
<phase>test</phase>
<goals>
<goal>integration-test</goal>
<goal>verify</goal>
</goals>
</execution>
</executions>
</plugin>
