When Obie F. was in town, he ended his talk by showing a final, extra-special productivity-boosting developer tool: Selenium on Rails. As it happens, it is our own Jonas “Danger Bay” Bengtsson who created that Rails plugin, on top of the ingenious Selenium testing software.
Jonas’ own screencast is a little dated, but it shows off perfectly what Selenium on Rails does. Take a look at it. Again, if you already did: now it comes with Obie’s seal of approval, should you need such a thing.
