GNATS is a portable incident/bug report/help request-tracking system which runs on UNIX-like operating systems. It easily handles thousands of problem reports, has been in wide use since the early 90s, and can do most of its operations over e-mail. Several front end interfaces exist, including command line, emacs, and Tcl/Tk interfaces. There are also a number of Web (CGI) interfaces written in scripting languages like Perl and Python.
IDebug is an advanced debugging framework for Java. It provides the standard core debugging and specification constructs such as assertions, debug levels and categories, stack traces, and specialized exceptions. Debugging functionality can be fine-tuned to a per-thread and/or a per-class basis, debugging contexts can be stored and recovered from persistent store, and several aspects of the debugging run-time are configurable at the meta-level.
JUnitX is a module on top of JUnit 3.2 by Kent Beck and Erich Gamma. It is a well-designed Java testing framework to write tests in the style of Extreme Programming. It allows you access to private and protected classes, methods, and fields in order to write improved and well-organized test cases. JUnit and an old version of JUnitX are also part of Together since version 5.5.
XPTest for Together provides two patterns and a module to allow the fast development of test cases. The TestCase pattern creates a class which has to be customized to contain test methods for a given class containing business methods. Using the TestPackage pattern, a class collecting all TestCases recursively can be created. The execution module allows one to start a Swing or AWT GUI to test single classes or packages in any granularity. It depends on JUnit by Kent Beck and Erich Gamma, and is designed to significantly speed up the development of Extreme Programming-inspired tests within the Together UML modeling tool and wanna-be-IDE. Since version 5.5, XPTest is also part of the Together distribution.
Struct::Compare is a Perl module that compares two values of any type and structure and returns true if they are the same. It does a deep comparison of the structures, so a hash of a hash of a whatever will be compared correctly. This is especially useful for writing unit tests for your modules.
pyprof is a wrapper around python's profile module for easily profiling python scripts without having to specify the whole path to them if they are in $PATH. It has command line arg and rc file configurable behaviors. If pyprof_auto is used, any python code can be profiled merely by setting the $PYPROF environment variable.
