testing controller with spec and factory girl, can't sign_in - ruby-on-rails

Question

I'm newbie on rails and testing rails applications. I try to test an existing rails application with rspec. I've just finished model tests and i have to complete controller tests too.But i have a problem with sign_in method on rspec. I've tried all solution methods on the internet but still i can't sign in like a user with rspec.
here is the my controller code, it's too simple;
class AboutController < ApplicationController
def index
end
def how_it_works
end
def what_is
end
def creative_tips
end
def brand_tips
end
def we_are
end
def faq
end
end
and here is the my spec code;
require 'spec_helper'
describe AboutController do
before(:all) do
#customer=Factory.create(:customer)
sign_in #customer
end
context 'index page :' do
it 'should be loaded successfully' do
response.should be_success
end
end
end
Here is the my factory code;
Factory.define :unconfirmed_user, :class => User do |u|
u.sequence(:user_name) {|n| "user_#{n}"}
u.sequence(:email){|n| "user__#{n}#example.com"}
u.sequence(:confirmation_token){|n| "confirm_#{n}"}
u.sequence(:reset_password_token){|n| "password_#{n}"}
u.password '123456'
u.password_confirmation '123456'
u.user_type :nil
end
Factory.define :user, :parent => :unconfirmed_user do |u|
u.confirmed_at '1-1-2010'
u.confirmation_sent_at '1-1-2010'
end
Factory.define :customer, :parent => :user do |u|
u.user_type :customer
end
Finally here is the my spec_helper code
ENV["RAILS_ENV"] ||= 'test'
require File.dirname(__FILE__) + "/../config/environment" unless defined?(Rails)
require 'rspec/rails'
require "paperclip/matchers"
Dir["#{File.dirname(__FILE__)}/support/**/*.rb"].each {|f| require f}
RSpec.configure do |config|
config.include Paperclip::Shoulda::Matchers
end
RSpec.configure do |config|
config.include Devise::TestHelpers, :type => :controller
end
RSpec.configure do |config|
config.mock_with :rspec
config.fixture_path = "#{::Rails.root}/spec/fixtures"
config.use_transactional_fixtures = true
end
gem file;
gem 'rails', '3.0.3'
gem 'mysql2', '< 0.3'
.
.
.
gem "devise" , "1.1.5"
.
.
.
group :test do
gem 'shoulda'
gem "rspec-rails", "~> 2.11.0"
gem "factory_girl_rails"
end
and here is the error;
Failures:
1) AboutController index page : should be loaded successfully
Failure/Error: sign_in #customer
NoMethodError:
undefined method `env' for nil:NilClass
# ./spec/controllers/about_controller_spec.rb:7:in `block (2 levels) in <top (required)>'
solution must be too easy but I'm newbie on rails and i can't find it :(

Answer 1

You have to make the sign-in step inside the it block in order for rspec to be able to access the response, e.g.:
it 'should be loaded successfully' do
sign_in #customer
response.should be_success
end

Answer 2

You have no subject.
require 'spec_helper'
describe AboutController do
before(:all) do
#customer=Factory.create(:customer)
sign_in #customer
end
context 'index page :' do
subject { Page }
it 'should be loaded successfully' do
response.should be_success
end
end
end
You might need to visit customers_path.
