Setting session variables in an RSpec Rails request spec

You are writing a spec with type: :request, i.e. an integration spec instead of a controller spec. Integration specs are wrappers around Rails' ActionDispatch::IntegrationTest class. I usually write controller tests using this instead of type: :controller, mainly because it exercises more of the request and response handling stack. So instead of writing something like get :index to start the request, you would write get books_path or similar.

One of the issues with using type: :request is that you lose the ability to

# Ajax testing with ruby and capybara
#
# Add this to spec/support
#
# When a link or button starts an ajax request, instead  of use Capybara
# click_link, click_button and click_link_or_button methods use click_ajax_link,
# click_ajax_button and click_ajax_link_or_button methods. You can still use
# capybara methods and right after it, call wait_for_ajax method.
#
# This methods will wait until Capybara.default_max_wait_time for the ajax request
