Ruby 如何将水豚纳入黄瓜项目的模块

我定义了一个模块：

module Support
  include Capybara::DSL

  def self.do_something
    click_link 'Questions'
  end
end

它位于features/support/support.rb

My env.rb：

require 'capybara'
require 'cucumber'
require 'capybara/cucumber'

Capybara.app_host = "http://www.stackoverflow.com"
Capybara.run_server = false
Capybara.default_driver = :selenium

我在steps.rb中调用模块的函数：

Support::do_something

我也有例外：

undefined method `click_link' for Support:Module (NoMethodError)

---

如何使Capybara在支持模块中可用？

Capybara应该是

扩展的
-ed，而不是
包含的
-ed：

module Support
  extend Capybara::DSL

  def self.do_something
    click_link 'Questions'
  end
end


module SupportModule
    class Support
        include Capybara::DSL

        def do_something
            click_link 'Questions'
        end
    end
end

s = SupportModule::Support.new
s.do_something
