StoryText (formerly PyUseCase) is an unconventional GUI testing tool written in Python. It currently has mature support for PyGTK, beta status support for Java Swing, SWT/Eclipse RCP, and Tkinter, and very basic support for wxPython. Instead of recording GUI mechanics directly, it asks the user for descriptive names and hence builds up a "domain language" along with a "UI map file" that translates it into the current GUI layout. Instead of an "assertion" mechanism, it auto-generates a log of the GUI appearance and changes to it, so as to use that as a baseline for text-based testing, using e.g. TextTest. Instead of requiring the tester to add "wait" statements by hand, it includes support for instrumenting code so that "waits" can be recorded.
Metawidget is a "smart user interface widget" that populates itself, at runtime, with UI components to match the properties of your business objects. Metawidget does this without introducing new technologies. It inspects your existing back-end architecture (such as JavaBeans, existing annotations, existing XML configuration files) and creates widgets native to your existing front-end framework (such as Swing, Java Server Faces, Struts, Android). Metawidget does not replace or hide your existing UI framework and guarantees that your investment in its technology and knowledge is as valid as always.
Puggle is a desktop search engine that provides full text search over files, folders, music, photos, Web pages, and other data that are stored locally on your computer. Puggle is able to create many different indices, each with a different configuration. For example, you may have a different index for your music collection as well as your documents. Each of them can be used on demand, simply by loading it. Furthermore, Puggle supports indexing of portable devices, like USB flash drives or external hard disks. The index will be stored in the device, using relative paths, allowing you to search over the data very quickly on any computer.
