Allow developer control of parallel testing
Allow developer control of parallel testing
Move the definition of parallel testing from the Maven pom file into the Jenkinsfile so that ci.jenkins.io continues to run the tests with one process per available core, while developers are allowed to configure the amount of parallel testing based on the configuration and use of their computer.
Developers can adjust parallel execution by passing a command line argument to Maven like this:
mvn clean -DforkCount=1C verify
Developers can define a Maven profile that sets the forkCount in their ~/.m2/settings.xml like this:
<profile>
<id>faster</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<properties>
<forkCount>.45C</forkCount>
</properties>
</profile>
With that entry in the settings.xml file, then 0.45C will be used for:
mvn clean verify
Testing done
Tests pass with -DforkCount=1C
on my Linux computer with Java 11.
