从WWW浏览器自动检测区域设置并使用Cucumber进行测试

  before_filter :set_locale

  private

    def set_locale
      xxx = request.env['HTTP_ACCEPT_LANGUAGE'].scan(/^[a-z]{2}/).first
      if xxx.match /^(en|fr)$/
        I18n.locale = xxx
      else
        I18n.locale = 'en'
      end
    end

我有一个场景:

  Scenario: Successful sign up
    Given I am an anonymous user
    And I am on the home page
    When ...

黄瓜 ,我得到一个错误:

Given I am an anonymous user                   # features/step_definitions/user_steps.rb:7
And I am on the home page                      # features/step_definitions/webrat_steps.rb:6
  private method `scan' called for nil:NilClass (NoMethodError)
  C:/workspace/jeengle/app/controllers/application_controller.rb:33:in `set_locale'
  c:/worktools/ruby/lib/ruby/1.8/benchmark.rb:308:in `realtime'
  (eval):2:in `/^I am on (.+)$/'
  features/manage_users.feature:8:in `And I am on the home page'

我已经试着在家里做了 步骤定义文件夹中的语句:

Before do
  request.env['HTTP_ACCEPT_LANGUAGE'] = "en"
end

但我还有一个错误:

  undefined method `env' for nil:NilClass (NoMethodError)

有人知道如何初始化/模拟吗 request.env['HTTP\u ACCEPT\u LANGUAGE'] 黄瓜?

更新

当我重写时,黄瓜测试通过了 设置语言环境 方法:

  xxx = request.env['HTTP_ACCEPT_LANGUAGE']    
  if xxx
    xxx = xxx.scan(/^[a-z]{2}/).first
    if xxx.match /^(en|ru)$/
      I18n.locale = xxx
  end
  else
    I18n.locale = 'en'
  end

这不是一个解决方案,但它是有效的。
