我正在尝试测试我的应用程序的 CanCan :create 规则。这是我的代码:
能力.rb
class Ability
include CanCan::Ability
def initialize(user)
user ||= User.new # guest user (not logged in)
# Admin user
if user.is_admin?
can :manage, :all
end
# Anyone
can :read, :all
# Regular logged in user
if user.persisted?
can :create, Comment
can :create, Node
end
end
end
user_controller_spec.rb
require 'spec_helper'
require "cancan/matchers"
describe User do
let(:user) { FactoryGirl.build(:user) }
it "has a valid factory" do
expect(user).to be_valid
end
# ...
describe "abilities" do
subject(:ability) { Ability.new(user) }
let(:user) { nil }
# ...
context "when is a regular user" do
let(:user){ FactoryGirl.build(:user) }
it "is able to create a new node" do
should be_able_to(:create, Node.new)
end
it "is not able to edit existing node" do
@node = FactoryGirl.build(:node)
should_not be_able_to(:update, @node)
end
end
end
end
基本上,当我实用地测试我的应用程序时,上面的代码可以正常工作,但是当我尝试运行测试时,它给了我:
Failures:
1) User abilities when is a regular user is able to create a new node
Failure/Error: should be_able_to(:create, Node.new)
expected to be able to :create #<Node id: nil, title: nil, body: nil, user_id: nil, thumbnail: nil, created_at: nil, updated_at: nil, url: nil, site_id: nil, score: 0, shares_facebook: 0, shares_twitter: 0, status: nil>
我如何测试这个:创建方法?提前感谢您的帮助。
