PI test failing when no tests are found in the project

[Kishore Babu]

Hi,

I am using pi test in parent pom, I am having the below issue when there are no tests in some of the modules.

 02:48:03 [INFO] Shared Lib .................................... FAILURE [0.491s]

 02:48:04 [ERROR] Failed to execute goal org.pitest:pitest-maven:1.0.0:mutationCoverage (default-cli) on project mf-was-client-sl: Execution default-cli of goal org.pitest:pitest-maven:1.0.0:mutationCoverage failed: No test library found on classpath. PIT requires either JUnit 4 (but can run JUnit 3 tests) or TestNG

02:48:04 [ERROR] See http://pitest.org for more details.

as per the post :  https://groups.google.com/forum/#!msg/pitusers/iBvdAYRbYAc/XZgZo1qSh98J

this issue is supposed be resolved in the version(1.0.0) I am using , any help is appreciated.

Kishore

Hi,

AFAIK the post you linked is different - that's about projects of type pom, like your parent pom. Your modules are probably of different type.

Is configuring PIT in pluginmanagement section in the parent pom and then declaring it in the modules you want to run it with in the build section an option?

HI Jarkko,

below is how I have configured it in the parent POM 

---------------------------partial pom file copied from my project------------------

            <plugin>

<groupId>org.pitest</groupId>

<artifactId>pitest-maven</artifactId>

<version>1.0.0</version>

<configuration>

<failWhenNoMutations>false</failWhenNoMutations>

 <inScopeClasses>

<param>com.ns.*</param>

 </inScopeClasses>

 <targetClasses>

<param>com.ns.*</param>

 </targetClasses>

 <outputFormats>

<outputFormat>XML</outputFormat> 

 </outputFormats>

</configuration>

                      </plugin>

  </plugins>

      </pluginManagement>

</build>

---------------------------------

and I have not mentioned any PIT related info in child modules, 

one of my modules have no unit tests.

regards,

Kishore.

and to add more information , one of my modules doesn't even have java source code.

it's just some packaging module and type is : <packaging>jbi-shared-library</packaging>

Hi,

It would probably be good if maven plugin would have a "skip" option available in the configuration. Maybe you should open a feature request about it.

What I have used is that in the parent pom I bind pit execution to a phase:

<plugin>

<groupId>org.pitest</groupId>

<artifactId>pitest-maven</artifactId>

<version>0.33</version>

<configuration>

<targetClasses>

<param>my.project.*</param>

</targetClasses>

<targetTests>

<param>my.project.*</param>

</targetTests>

<mutators>

<mutator>ALL</mutator>

</mutators>

<outputFormats>

<outputFormat>HTML</outputFormat>

<outputFormat>XML</outputFormat>

</outputFormats>

<timestampedReports>false</timestampedReports>

</configuration>

<executions>

<execution>

<id>pit-execute-mutation-coverage</id>

<phase>verify</phase>

<goals>

<goal>mutationCoverage</goal>

</goals>

</execution>

</executions>

</plugin>

which is bound to verify phase of the project and will be run with "mvn verify", and then I unbind the phase in modules I don't want it to be run

  <build>

  <plugins>

<plugin>

<groupId>org.pitest</groupId>

<artifactId>pitest-maven</artifactId>

<executions>

<execution>

<id>pit-execute-mutation-coverage</id>

<phase/>

</execution>

</executions>

</plugin>

</plugins>

  </build>

Ah, feature request about it already exists:

https://github.com/hcoles/pitest/issues/106

There's also another hack workaround mentioned.
