Marathon is a GUI test tool that allows you to play and record scripts against a Java Swing UI. It's written in Java, and uses Python and Ruby as its scripting language (the emphasis being on an extremely simple, readable syntax that customers/testers/analysts feel comfortable with). Marathon includes a recorder, editor, player, and debugger to simplify working with test scripts.
Jaffa (Java Application Framework For All) is an enterprise-focused Java framework for rapid application development. It provides a complete Java Web application development stack, extending exsiting projects like Tomcat and Struts at the frontend with MVC-based web widgets, all the way through to a high-performance lightweight O/R persistence engine, with plenty of rich features in between including rules engines, declarative application, and data security. In addition to the runtime framework, there is a suite of component templates and other tools for rapid application development, including a TogetherSoft plug-in for UML intergration.
Cobra is a general purpose programming language with a clean, high-level syntax. It provides language level features for quality, including first class unit tests and Eiffel-style contracts. It supports both static and dynamic binding. Cobra is a compiled language with good run-time performance, but also provides some scripting conveniences such as a pound-bang line (#!) and one step compile-and-run. Cobra runs on Linux, Mac, Windows, and anywhere else that Novell Mono or MS .NET exist, including handhelds.
Pin is an ATOM-like instrumentation tool for Linux executables. It allows arbitrary code (written in C or C++) to be injected at arbitrary places in an executable. Unlike Atom, Pin does not perform the instrumentation statically by rewriting the executable, but rather dynamically by adding instrumentation while the executable is running. Currently supported platforms include IA-32, Intel Xscale, and Itanium processors.
cutee is a C++ unit testing environment that makes it really easy to create and run tests of a library or application. It will automatically generate Makefiles, runner classes (classes that execute test functions), and main test application code. It will also automatically update Makefiles and support classes whenever you add new test functions or modify old ones. It easily integrates with plain Makefile projects and with Autotools.
"jscpp" is an ANSI C preprocessor and language parser that can analyze and instrument C code. Currently, its most prominent application is to add tracing to existing C programs simply by recompiling and linking it with the "jscc" compiler frontend. The standard tracing shows when a function is entered or left along with the parameters passed or return values. It is also possible to trace each source line and watch read/write access to simple variables. Tracing is achieved by instrumenting the source code before calling the system compiler. The program is modular and can be easily extended to other kinds of source code modifications.
MockDoclet is a tool for generating mock objects for Java classes and interfaces to aid in unit testing classes that are tightly coupled to other components. It is an active code generation tool that scans interfaces for JavaDoc style @mock tags at build time to generate the appropriate mock objects. It is built on top of XDoclet and the MockObjects framework, and is designed to be used with JUnit and Ant.
