How do I set up a session value in Capybara?

Question

I am developing an app for Shopify and I want to do integration testing.

I need to be able to store some values in the session variable, so that authentication works.

How could I do that?

I use Capybara and Capybara-webkit.

The accepted answer suggests rack_session_access. It works by inserting middleware controllers to edit and update the session state, then has capybara visit that page and submit a form with the session data. Very ingenious! But unnecessary if you are using Warden (directly or through Devise).

Warden has a hook on_next_request that gives access to the warden mechanism, which can be used to set session keys directly. I threw this together to bundle it up in rspec:

Create spec/support/inject_session.rb:

module InjectSession   include Warden::Test::Helpers    def inject_session(hash)     Warden.on_next_request do |proxy|       hash.each do |key, value|         proxy.raw_session[key] = value       end     end   end end 

In spec/spec_helper.rb include the module in feature specs:

RSpec.configure do |config|     config.include InjectSession, :type => :feature end 

Then sample use in a spec might be:

   inject_session :magic => 'pixie dust', :color => 'pink'     visit shopping_cart_path    page.should be_all_sparkly_and_pink # or whatever
