Ruby on rails 为什么Rspec会忽略我在application\u controller.rb中设置的默认\u url\u选项

我已经覆盖了application.rb中的方法default\u url\u选项

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception
  before_action :set_locale

  def redirect_to_root
    redirect_to root_path
  end

  private

    def default_url_options(options={})
      { locale: I18n.locale }.merge options
    end

    def set_locale
      if params[:locale].blank?
        logger.debug "* Accept-Language: #{request.env['HTTP_ACCEPT_LANGUAGE']}"
        abbr = extract_locale_from_accept_language_header
        I18n.locale = if Language.find_by(abbr: abbr).nil?
                        logger.debug "* Unknown Language"
                        I18n.default_locale
                      else
                        abbr
                      end
        logger.debug "* Locale set to '#{I18n.locale}'"
      else
        I18n.locale = params[:locale]
      end
    end

    def extract_locale_from_accept_language_header
      request.env['HTTP_ACCEPT_LANGUAGE'].scan(/^[a-z]{2}/).first
    end
end

为什么rspec不通过我在ApplicationController中设置的defautl url选项（locale）？如何告诉rspec这样做？

我遇到了类似的问题，但测试了ActionMailer类。它不是ActionController，因此未调用

default\u url\u options

我必须在配置中配置默认语言环境：

# config/environments/test.rb
Rails.application.configure do
  # ...

  config.action_mailer.default_url_options = {:host => 'localhost:3001', :locale => :de}
end

您的配置中可能有类似的行覆盖了

url\u选项

# config/environments/test.rb
Rails.application.configure do
  # ...

  config.action_mailer.default_url_options = {:host => 'localhost:3001', :locale => :de}
end
