# This works with steak 0.3.x and rspec 1.x
# For steak --pre and rspec 2 see this fork: http://gist.github.com/448487 

# Put this code in acceptance_helper.rb or better in a new file spec/acceptance/support/javascript.rb

Spec::Runner.configure do |config|

  config.before(:each) do
    Capybara.current_driver = :selenium if options[:js]
  end

  config.after(:each) do
    Capybara.use_default_driver if options[:js]
  end

end

your_feature_with_js_spec.rb

#...

scenario "Scenario that needs Javascript", :js => true do
  #...
end

scenario "Scenario that doesn't need Javascript" do
  #...
end

¿How can I use this with Rspec 2?

Rspec.configure do |config|
  config.before(:each) do
    Capybara.current_driver = :selenium if options[:js]
  end
[...]

I don't have an options() method :-(

Never tried with RSpec 2, but you may find this post useful:

http://blog.davidchelimsky.net/2010/06/14/filtering-examples-in-rspec-2/

Yeah, I've seen that one, but it only talks about using example metadata to filter spec execution. I am looking at Rspec2 source code, I'll post anything I find about this issue here.

I have found the solution and forked your gist. Thanks for your input!

Please provide a link to the final solution to this issue. I also want to use "tags" with Steak and RSpec 2 :)

Papipo forked this gist and posted there his solution (see the forks section at the top right of this page):

Thanks :)

Looks like that isn't required anymore: http://jeffkreeftmeijer.com/2011/capybara-ate-swinger/
