rspec-rails supports integration with Capybara out of the box by adding its Capybara::DSL (visit/page) and Capybara::RSpecMatchers to the examples in the applicable directories, which differ slightly between Capybara 1.x and Capybara >= 2.x.

Capybara::DSL

Adds the visit and page methods, which work together to simulate a GET request and provide access to the result (via page).

Capybara::RSpecMatchers

Exposes matchers used to specify expected HTML content (e.g. should_not have_selector will work correctly).

Upgrading to Capybara-2.0

Many users have been confused by the co-existence of the the Capybara::DSL (visit/page) alongside the rack-test DSL (get|post|put|delete|head/response.body) in examples in spec/requests and spec/controllers. As of rspec-rails-2.11.1 and capybara-2.0.0.beta2, these are separated as follows:

Capybara::RSpecMatchers is added to examples in:

If you're upgrading to Capybara-2.0 and you used visit/page in spec/requests you'll want to move those examples to spec/features and they should just work.

If you want to leave those examples in spec/requests, you can include Capybara::DSL in those examples yourself as follows, but this is absolutely not recommended as you will be overriding the intended behavior and accepting the risks associated with doing so:

# not recommended!
RSpec.configure do |c|
  c.include Capybara::DSL, :file_path => "spec/requests"
end
