BFTS is a branch of rubicon with the intent of auditing all of rubicon against the latest version of 1.8.x, stripping all the cruft, and getting everything up to date again. rubicon is dead and the authors have shown no interest in getting things moving again. BFTS hoped to fix that.
Later… BFTS moved into the jruby (HUGE) test compendium and some of BFTS leaked into rubyspec.
The project is now dead as there are better alternatives out there.
