Testoob is the advanced Python test runner and testing framework that spices up any existing unittest test suite.
Version 1.15 (Oct. 2009) adds better Python 2.6, IronPython, and Jython support, as well as test coverage improvements, better color support, and some new options and bugfixes.
This version wouldn't have been possible without the help of Ronnie van 't Westeinde.
