清扫方法在rspec中缺少方法'expire_fragment'

我正在使用清扫工来清除片段缓存,一切都在开发中正常工作,但我的规格中收到错误

2) Admin - Categories #index displays all categories
     Failure/Error: create_basic_category_set
     NoMethodError:
       undefined method `expire_fragment' for #<NavigationSweeper:0x007fdc01a10970 @controller=nil>
     # ./app/sweepers/navigation_sweeper.rb:5:in `after_save'
     # ./spec/support/utilities.rb:21:in `create_basic_category_set'
     # ./spec/features/admin/categories_spec.rb:5:in `block (2 levels) in <top (required)>'

这是清扫车

class NavigationSweeper < ActionController::Caching::Sweeper
  observe Category, Product, Series

  def after_save(record)
    expire_fragment 'navigation'
  end
end

这就是我在控制器中使用它的地方

class Admin::CategoriesController < Admin::BaseController
  before_filter :set_up_nav_array
  cache_sweeper :navigation_sweeper, only: [ :destroy, :update, :create, :update_positions ]

  def index
    @roots = Category.roots
  end

这是规范(多个实例)失败的地方

pickers = FactoryGirl.create(:category, :name => "Pickers")

任何人都知道为什么它可能找不到那种方法?

答案 0 :(得分:0)

好的,这里最好的策略似乎是在spec_helper.rb

中存根这样的方法
RSpec.configure do |config|
  config.before(:each) do
    NavigationSweeper.any_instance.stub(:expire_fragment)
  end
end
