Inspired by the Apache Lucene project's infrastructure, this project
brings a refactored, stand-alone runner for JUnit 4.x tests, which
encapsulates built-in repeatable randomized tests, threading and timeout
control, parameter factories, thread execution groups and more. Everything
is JUnit compatible and will work in your favorite IDE.
On top of that, the project comes with ANT and Maven integration allowing execution of tests in concurrent isolated JVMs, load-balancing and multiple options for reporting, including attractive reports and results visualizations.
