Software Testing Automation Framework
The Software Testing Automation Framework (STAF) is an open source project that enables users to create cross-platform, distributed software test environments. The project is licensed using the Common Public License (CPL). STAF includes a number of services that provide specific functionality. The most prominent of these is the test execution engine called STAX. Other services provide file system, inter-process communications, e-mail, and HTML support, among others.
STAF was originally developed for internal use by IBM in the 1990's. IBM supports users of STAF through extensive online documentation and user forums.
