[01/26/2007] The Firefox extension is now available for download. It's nowhere near complete yet, but it does have the Acceptance-Fitnesse format to get you started.
[01/19/2007] We have a proof of concept working. I'm using it for a project here and it works fine. Now to productize it..
Welcome to Tk-Acceptance
The Tk-Acceptance framework assists teams in testing Ajax features using Fitnesse and Selenium together.
It is a set of glue code to help users get started with Fitnesse and Selenium RC and start creating an acceptance testing infrastructure of their own. For users, it provides a Selenium IDE syntax script to create selenium fixtures in fitnesse wiki table format.
We are still pretty early on this project, and we may need you! We'd love your input or help.
