I always feel frustration at this question, I can't believe that sauce labs hasn't taken off. Use capybara as the driver layer, and a proper test framework that separates the different layers, and sauce labs to hit any browser matrix you want. Tie it into a CI system and never worry about this again - it's a solved problem, and it was solved by Sauce Labs. disclaimer: I used to work there, and put my blood, sweat, and tears into building it out just for situations like this.
