Using Devise in rspec feature tests - ruby-on-rails

Question

I've written the following rspec feature test spec:
require "rails_helper"
RSpec.describe "Team management", type: :feature do
user_sign_in
describe "User creates a new team" do
...
expect(page).to have_link("#{team_name}")
end
end
The user_sign_in method is defined in my rails_helper.rb:
ENV['RAILS_ENV'] ||= 'test'
require 'spec_helper'
require File.expand_path('../../config/environment', __FILE__)
require 'rspec/rails'
require 'capybara/rails'
...
module UserSignInHelpers
def user_sign_in
before(:each) do
#request.env['devise.mapping'] = Devise.mappings[:user]
#current_user = FactoryGirl.create(:user)
#current_user.confirm
sign_in :user, #current_user
end
end
end
RSpec.configure do |config|
...
# The different available types are documented in the features, such as in
# https://relishapp.com/rspec/rspec-rails/docs
config.infer_spec_type_from_file_location!
config.extend UserSignInHelpers, type: :controller
config.extend UserSignInHelpers, type: :feature
config.include Devise::TestHelpers, type: :controller
config.include Devise::TestHelpers, type: :feature
end
The user_sign_in method works from all of my controller specs but when I run my feature spec it fails with:
Team management
User creates a new team
example at ./spec/features/user_creates_a_new_team_spec.rb:19 (FAILED - 1)
Failures:
1) Team management User creates a new team
Failure/Error: Unable to find matching line from backtrace
NoMethodError:
undefined method `env' for nil:NilClass
# /Users/xxxx/.rvm/gems/ruby-2.2.1/gems/devise-3.5.1/lib/devise/test_helpers.rb:24:in `setup_controller_for_warden'
I don't understand why this works in controller tests and not feature tests. Is there something I can do make this work in feature tests?

Answer 1

There is a basic problem with what you are trying to do. (Devise work on top of Warden)Warden is a
Rack middleware, but RSpec controller specs don't even include Rack,
as these types of specs are not meant to run your full application
stack, but only your controller code.

Test with Capybara
I have a simple support helper, that allows me to login and logout users:
module Auth
def create_user!
#user = User.create(email: 'foo#bar.com', password: '11111111')
end
def sign_in_user!
setup_devise_mapping!
sign_in #user
end
def sign_out_user!
setup_devise_mapping!
sign_out #user
end
def setup_devise_mapping!
#request.env["devise.mapping"] = Devise.mappings[:user]
end
def login_with_warden!
login_as(#user, scope: :user)
end
def logout_with_warden!
logout(:user)
end
def login_and_logout_with_devise
sign_in_user!
yield
sign_out_user!
end
def login_and_logout_with_warden
Warden.test_mode!
login_with_warden!
yield
logout_with_warden!
Warden.test_reset!
end
end
in a feature:
RSpec.describe "Team management", type: :feature do
describe "User creates a new team" do
login_and_logout_with_warden do
# tests goes here
end
end
end
in a controller:
RSpec.describe "Team management", type: :controller do
describe "User creates a new team" do
login_and_logout_with_devise do
# tests goes here
end
end
end
