Error in testing ruby on rails using rspec in tutorial - ruby-on-rails

Question

I am newbie for ruby on rails i am just reading the http://ruby.railstutorial.org/chapters/static-pages#top as the tutorial saying, i have created the sample_app bundle or project. Now in section 3.2.1 i am testing the app.
first i run the following from the cmd
$ rails generate integration_test static_pages
This created the static_pages_spec.rb in the spec/requests directory.
Now add the following code in spec/requests/static_pages_spec.rb
require 'spec_helper'
describe "Static pages" do
describe "Home page" do
it "should have the content 'Sample App'" do
visit '/static_pages/home'
expect(page).to have_content('Sample App')
end
end
end
at this stage i add the following code in sample_app/spec/spec_helper.rb file
config.include Capybara::DSL
so my file look like
# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'
# Requires supporting ruby files with custom matchers and macros, etc,
# in spec/support/ and its subdirectories.
Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f }
# Checks for pending migrations before tests are run.
# If you are not using ActiveRecord, you can remove this line.
ActiveRecord::Migration.check_pending! if defined?(ActiveRecord::Migration)
RSpec.configure do |config|
# ## Mock Framework
#
# If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
#
# config.mock_with :mocha
# config.mock_with :flexmock
# config.mock_with :rr
# Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
config.fixture_path = "#{::Rails.root}/spec/fixtures"
# If you're not using ActiveRecord, or you'd prefer not to run each of your
# examples within a transaction, remove the following line or assign false
# instead of true.
config.use_transactional_fixtures = true
# If true, the base class of anonymous controllers will be inferred
# automatically. This will be the default behavior in future versions of
# rspec-rails.
config.infer_base_class_for_anonymous_controllers = false
# Run specs in random order to surface order dependencies. If you find an
# order dependency and want to debug it, you can fix the order by providing
# the seed, which is printed after each run.
# --seed 1234
config.order = "random"
config.include Capybara::DSL
end
i have app/views/static_pages/home.html.erb
<h1>Sample App</h1>
<p>
This is the home page for the
Ruby on Rails Tutorial
sample application.
</p>
and run the command
$ bundle exec rspec spec/requests/static_pages_spec.rb
it was giving the error

i have installed the capybara as per direction in git
step 1->gem install capybara
step 2->require 'capybara/rails' in sample_app/spec/spec_helper.rb
but still it was showing the load error of capybara rails
now i run the same command i.e $ bundle exec rspec spec/requests/static_pages_spec.rb
i got the following error

end
gem 'rubyzip'
if i remove the config.include Capybara::DSL then i get fail error
Please give me right direction ...thanks in advance

Answer 1

Since you're using Bundler (i.e. you have a Gemfile), you need to make sure Capybara is in there too, otherwise your rails app won't know the gem is installed. Update your Gemfile to include capybara in the development/test environments:
group :development, :test do
gem 'rspec-rails', ">= 2.0.0.beta"
gem 'capybara'
end
