Changes :

Fixes:

  • fixed NullPointerException in PCI operator
  • fixed NullPointerException in PNC operator

Modifications:

  • mujava.app.Console has been deprecated, mujava.app.Main is used instead
  • mujava++ no longer support the old console arguments, now uses only a .properties file
  • mujava.app.Main arguments are:
    • -p[roperties] : to give a specific .properties file to mujava++
    • -o[perators] : prints all mutation operators information
    • -h[elp] : prints mujava++ help
  • added all new supported configurations into default.properties
  • cleanned up some code

Additions:

  • added support for several configurations to be defined in .properties files
  • improved memory usage when running mutation score

IMPORTANT

For the best performance please use -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled as VM arguments and run muJava++ using java 8. A Java 8 VM improves memory usage since permGen is now a part of the heap, getting more allowed memory and can be garbage collected.

New configuration parameters

  • mutation.advanced.prvo.enableSameLenght= [BOOLEAN] : Enable/disable mutations that changes one element of an expression without affecting it's length
