Acceptance tests for your application may require that a test user be logged in. To do this in your application you can either sign in the user using capybara by visiting the sign in url and entering valid credentials, or you can stub the logged in user.
Signing in via Capybara is perhaps the most 'correct' way since we want our tests to be as close to real world conditions as possible, however if you have more than a few tests, these few extra actions for each logged in test can be quite time consuming. The alternative is to use warden's built in stubbing actions to make your application think that a user is signed in but without all of the overhead of actually signing them in.
To do this, you'll need to include warden test helpers and turn on test mode
include Warden::Test::Helpers Warden.test_mode!
Then you can make a call to the warden helper
login_as with a user resource and specifying the
:scope => :user to 'log in' a test user.
user = FactoryGirl.create(:user) login_as(user, :scope => :user)
If you are using devise's confirmable module, you will need to ensure that the newly created user also has the 'confirmed_at' field filled in:
user = FactoryGirl.create(:user) user.confirmed_at = Time.now user.save
To make sure this works correctly you will need to reset warden after each test you can do this by calling
If for some reason you need to log out a logged in test user, you can use Warden's
Now you should be good to go.
If you're wondering why we can't just use Devise's built in
sign_out methods, it's because these require direct access to the request object which is not available while using Capybara. To bundle the functionality of both methods together you can create a helper method.
If you have trouble using Warden's login_as method with the capybara-webkit driver, try setting run_callbacks to false in the login_as options struct
user = FactoryGirl.create(:user) login_as(user, :scope => :user, :run_callbacks => false)
make sure to set transactional fixtures to false in your Rspec spec_helper.rb file
RSpec.configure do |config| config.use_transactional_fixtures = false end

login_as may not work with Poltergeist when js is enabled on your test scenarios. To fix this, add this file to your app.

Good luck and happy testing. Blog post with more details
