Coverage always zero percent.

[jeffw...@gmail.com]

I have a multi-module project that I am trying to get code coverage from. In my root pom i have set up an it profile like so:

{code}
<profile>
<id>it</id>
<modules>
<module>model</module>
<module>common</module>
<module>business</module>
<module>eis</module>
<module>web</module>
</modules>

<build>
<pluginManagement>
<plugins>
<!-- ignore unit tests for now -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<skipTests>true</skipTests>
</configuration>
</plugin>
</plugins>
</pluginManagement>
</build>
</profile>
{code}

In my web module where I have all my integration tests currently, I have set things up like this:

{code}
<profile>
<id>it</id>
<build>
<testResources>
...
</testResources>
<plugins>
<!-- ignore unit tests for now -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>

</executions>

<plugin>

</properties>
<deployables>

</deployables>
</configuration>
</configuration>
</plugin>
</plugins>
</build>
</profile>
{code}

With the above settings, mvn completes successfully if I do a mvn clean verify -Pit, but when I look at my reports, I am getting zero percent coverage for the 188 integration tests that I have. If I uncomment the cargo.jvmargs, all my integration tests return 404 errors. What am I doing wrong?

Hi,

what do you see when you click on the "Sessions" link in the top right
corner of your HTML report? Are your classes under test listed?

Best regards,

Hey Marc,

Unfortunately they are not listed there. I assumed putting the argLine in the maven-failsafe-plugin would have used my IT tests for the code coverages. How do I make classes be used with the sessions???
Thank you for helping me!!!

Typical reasons for this are:

1) Wrong includes/excludes configuration (don't configure those at all
at the beginning)
2) JaCoCo agent attached to wrong JVM (e.g. in case of client/server IT
scenarios)

Thanks again for helping me, but I'm unsure on how to change my configuration to accomplish your suggestions.

So I put an includes with the package name like "com.company.*" in the jacoco-maven-plugin for the prepare-agent goal and now I'm seeing my test classes in the sessions tab, but I am still getting zero coverage in the coverage report. What else am I missing?

Many Thanks,
Jeff

[Marc Hoffmann]

Hi Jeff,

so your classes show up

a) on the sessions page and
b) in the coverage hierarchie with 0% coverage

Right? This means that the classes used at runtime are different classes
than the one at report generation time.

Hey MRC,

So how would I make the classes used at runtime be the same classes that are used at report generation time?

Thank you so much for your time!!!

Hey MRC,

I posted a sample app that shows exactly what I am seeing. Is there any chance you can eyeball and let me know what I am doing wrong??? https://github.com/jeffwysong/coverage-multi-module

Thanks for your time.
