When I updated a few projects to Rails 2.0 last year, selenium-on-rails stopped working … some issue with routing and the lame way selenium-on-rails adds its routes. I didn’t spend the time to figure out exactly what the routing problem was, but did manage to hack a quick fix into routes.rb. This feels like the Wrong Way for an ultimate fix but it at least solves the immediate problem. Shove these rules into your routes.rb and the /selenium path should start resolving again…
