In RSpec 3 the example variable will no longer be defined. It will instead be passed into blocks as an argument. This requires a minor change to Capybara's RSpec.configure before hooks.
I've made a commit with what I think is the change that needs to happen, I'm not sure what branch it should go against though.
See rspec/rspec-core#666 and rspec/rspec-rails#782
I accidentally merged and then reverted #1123, which unfortunately broke the build. Let's leave this open for now at least until we find a better solution.
Thanks. I opened this up so we could start trying to get this resolved. Hopefully sometime this week we'll have a more complete PR put together.
I've got a good PR ready now that I'll be submitting shortly. It should allow rspec-rails to use capybara while having no adverse effects to capybara.
This is now merged. Thanks!
