Testing Warden/Devise with Steak

warden.rb

# Create a file `spec/acceptance/support/warden.rb' with the following 
# contents:

Spec::Runner.configure do |config|
  config.include Warden::Test::Helpers, :type => :acceptance
  config.after(:each, :type => :acceptance) { Warden.test_reset! }
end

# Or, if you're using RSpec 2 / Rails 3, the contents should be the following 
# instead:

RSpec.configure do |config|
  config.include Warden::Test::Helpers, :type => :acceptance
  config.after(:each, :type => :acceptance) { Warden.test_reset! }
end

your_spec.rb

# Then in your features you'll only need to call the `login_as` or `logout` 
# methods. More info here: http://wiki.github.com/hassox/warden/testing

feature "Home page" do

 background do
   @user = User.create(...) # Or use fixtures, factories or whatever, even a 
                            # stub user
   login_as @user
   visit home_page
 end
 
 # ...
end

Alternatively, it might be a better practice to just visit the login page and fill and send the form.

This Warden helpers might be handy if you're using some kind of external authentication like OpenID, OAuth, etc.
