我想用rspec指定我的控制器before_filter.
我想为它使用ActionController :: Testing :: ClassMethods#before_filters.
我想为它使用ActionController :: Testing :: ClassMethods#before_filters.
我在导轨c中得到了这些结果：
2.0.0p353 :006 > ActionController::Base.singleton_class.send :include,ActionController::Testing::ClassMethods 2.0.0p353 :003 > EquipmentController.before_filters
=> [：process_action,：process_action]
但实际上这是我行动的过滤器：
class EquipmentController < ApplicationController before_filter :authenticate_user!
有任何想法吗？
解决方法
这就是我在项目中所做的：
# spec/support/matchers/have_filters.rb
RSpec::Matchers.define :have_filters do |kind,*names|
match do |controller|
filters = controller._process_action_callbacks.select{ |f| f.kind == kind }.map(&:filter)
names.all?{ |name| filters.include?(name) }
end
end
# spec/support/controller_macros.rb
module ControllerMacros
def has_before_filters *names
expect(controller).to have_filters(:before,*names)
end
end
# spec/spec_helper.rb
RSpec.configure do |config|
config.include ControllerMacros,type: :controller
end
然后你可以在控制器规格中使用它,例如：
# spec/controllers/application_controller_spec.rb
require 'spec_helper'
describe ApplicationController do
describe 'class' do
it { has_before_filters(:authenticate_user) }
end
end
