`require': cannot load such file -- capybara/rspec (LoadError)

Question

I tried to test my project. It was working before and I don't know what i did to whenever i type bundle exec rspec spec/ it says cannot load such file -- capybara/rspec (LoadError). And Please I need an advice to which one is good for testing my MVC in ruby on rails as a newbie.

Gemfile:
------------

group :test do
  # Pretty printed test output
  gem 'turn', :require => false
  gem 'minitest'
  gem 'capybara', '1.1.2'
  gem 'rb-inotify', '0.8.8'
  gem 'libnotify', '0.5.9'
  gem 'guard-spork', '0.3.2'
  gem 'spork', '0.9.0'
  gem 'spork-testunit'
  gem 'guard-test'
  gem 'ruby-prof'
  gem 'factory_girl_rails', '1.4.0' 
  if RUBY_PLATFORM =~ /linux/
    gem 'capybara-webkit'
  end
  gem 'launchy'
end

group :development, :test do
  gem 'rspec-rails', '2.10.0'
  gem 'guard-rspec', '0.5.5'
end

spec_helper:

require 'rubygems'
#require 'factory_girl'
#uncomment the following line to use spork with the debugger
#require 'spork/ext/ruby-debug'


  ENV["RAILS_ENV"] ||= 'test'
  require File.expand_path("../../config/environment", __FILE__)
  require 'rspec/rails'
  require 'rspec/autorun'
  require 'capybara/rspec'
  require 'capybara/rails'

  # 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}

  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
  config.mock_with :rspec

  # 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 = false

  # 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

  #Capybara.default_driver = :selenium
  Capybara.javascript_driver = :webkit
end

Thanks in advance!!!

Answer 1

I hope you did install all required gems? Using bundle install BTW did you change Gemfile, in that case you would be required to install Gems using bundle install.

You could check list of gems available by gem list

Regarding second part of the question, which testing API to use. It is matter of choice. You could stick with rpsec and if you find it falls short of your expectation, then look out for change.
