Feature: Generate cucumber
  In order to use cucumber in my ruby project
  As a developer
  I want to generate the cucumber boilerplate in my project
  
  Scenario: Run `bddgen cucumber` in an empty project
    Given a current working directory named "myproject"
    When I run "bddgen cucumber"
    Then the following files should be created:
      | features/support/env.rb                      |
      | features/support/helpers.rb                  |
      | features/step_definitions/myproject_steps.rb |
      | Gemfile                                      |
      | Rakefile                                     |
    And the file "features/support/env.rb" should match the template "features/support/env.rb"
    And the file "features/support/helpers.rb" should contain exactly:
      """
      module Myproject
        module CucumberHelpers
        end
      end
      
      World(Myproject::CucumberHelpers)
      
      """
    And the file "Gemfile" should contain exactly:
      """
      source 'http://rubygems.org'
      
      gem 'rake'
      gem 'cucumber'
      
      """
    And the file "Rakefile" should contain the bundler setup
    And the file "Rakefile" should contain the cucumber tasks
    
    Scenario: Run `bddgen cucumber` in a project with an existing Gemfile
      Given a current working directory named "myproject"
      And a file named "Gemfile" with:
        """
        source 'http://custom.com'
        gem 'special'
        """
      When I run "bddgen cucumber"
      Then the file "Gemfile" should contain exactly:
        """
        source 'http://custom.com'
        gem 'special'
        gem 'cucumber'
        
        """

    Scenario: Run `bddgen cucumber` in a project with an existing Rakefile
      Given a current working directory named "myproject"
      And a file named "Rakefile" with:
        """
        require 'custom'
        require 'special'
        """
      When I run "bddgen cucumber"
      Then the file "Rakefile" should contain "require 'custom'"
      And the file "Rakefile" should contain "require 'special'"
      And the file "Rakefile" should contain the cucumber tasks
