I was surprised at DHH's love for capybara. I've always thought the capybara tests as the most cumbersome, unreliable and generally superfluous tests in our suites. They are at best slow and hard to maintain.
Together with our move from big backend rails apps to big client side apps I think we should also be moving our integration tests to the client side.
There's some great testing runners in javascript, you almost don't notice it's not rspec, and I think it could be much more intuitive then the in my opinion awkward Capybara.
No bad feelings towards the Capybara people by the way, it's great software that ostensibly has taken a lot of effort to develop. I just hope we can move to a different solution.
