如何模拟黄瓜/水豚的IP地址？

Question

我使用的是黄瓜和水豚，我想一个办法来模拟请求的IP地址，就像这样：

Given the request ip address is "10.1.2.3" 

Answer 1

我解决它通过将IP地址的环境变量：

When /^the request ip address is "([^\"]*)"$/ do |ip_address| 
    ENV['RAILS_TEST_IP_ADDRESS'] = ip_address 
    end 

application_controller.rb：

before_filter :mock_ip_address 

    def mock_ip_address 
    if Rails.env == 'cucumber' || Rails.env == 'test' 
     test_ip = ENV['RAILS_TEST_IP_ADDRESS'] 
     unless test_ip.nil? or test_ip.empty? 
     request.instance_eval <<-EOS 
      def remote_ip 
      "#{test_ip}" 
      end 
     EOS 
     end 
    end 
    end 

Answer 2

我Leventix的和Ramon的解决方案的组合：

规格/支持/ remote_ip_monkey_patch.rb

module ActionDispatch 
    class Request 

    def remote_ip_with_mocking 
     test_ip = ENV['RAILS_TEST_IP_ADDRESS'] 

     unless test_ip.nil? or test_ip.empty? 
     return test_ip 
     else 
     return remote_ip_without_mocking 
     end 
    end 

    alias_method_chain :remote_ip, :mocking 

    end 
end
