Since IBS Integrator compiles to .class files, you should be able to write JUnit tests in Java against those classes, and run them however you’d normally run JUnit tests (kick off Ant or Maven, open Eclipse and run them from there, etc.). And I can’t think of any reason to use another technology (phpunit, rspec, etc.) for writing tests of Java code; JUnit seems like the clear winner here.
