Why can't I access Rails' URL helpers from my Rspec tests?

问题

Initially I wrote my tests with Cucumber and Capybara, and that worked fine.

Then I switched to using Rpsec and Capybara, and that worked fine too.

Then I deleted my gemlock file while trying to get the asset pipeline working and suddenly the URL helpers in my tests stopped working.

Sample error:

 Failure/Error: visit report_areas_path(@report)
 NoMethodError:
   undefined method `visit' for #<RSpec::Core::ExampleGroup::Nested_1::Nested_1:0x007f978c64e058>
 # ./spec/features/area_spec.rb:12:in `block (3 levels) in <top (required)>'

I'd like to get the URL helpers working again so my tests can guide me as I finish implementing the asset pipeline. How can I fix this?

All my tests are in /spec/features.

Relevant software follows...

/spec/spec_helper.rb:

require 'rubygems'
require 'spork'

Spork.prefork do
end

Spork.each_run do
  # This code will be run each time you run your specs.    
end    

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

require 'capybara/rspec'
require 'capybara/rails' 
require 'capybara/dsl' 
require 'capybara-screenshot/rspec'

Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}

RSpec.configure do |config|
  config.mock_with :rspec
  config.fail_fast = true
  config.fixture_path = "#{::Rails.root}/spec/fixtures"
  config.use_transactional_fixtures = true
  config.before(:each) { ActionMailer::Base.deliveries.clear }
  config.use_instantiated_fixtures = false 
  config.include(Capybara, :type => :integration) 
end
