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.

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::DSL is added to examples in:

• spec/features

Capybara::RSpecMatchers

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

Capybara::RSpecMatchers is added to examples in:

• spec/features
• spec/controllers
• spec/views
• spec/helpers
• spec/mailers
