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 cron, file system, inter-process communication, 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.
