If the properties have been set in the POM, if they have been set using a property value (e.g. <forkCount>${some.property}</forkCount>) then you can override the property from the command line (i.e. "mvn -Dsome.property=2 test"). If the properties have been set with hard-coded values (e.g. <forkCount>1</forkCount>) then you have no other choice than to edit the POMs. And then you can tell Maven to parallelize the build with -T. Actually, everything seems to be described in the Surefire documentation [2] [1] https://maven.apache.org/surefire/maven-surefire-plugin/test-mojo.html#forkCount [2] https://maven.apache.org/surefire/maven-surefire-plugin/examples/fork-options-and-parallel-execution.html
