我第一次测试CanCan的能力,但遇到了问题。即使我在can: invite_to块内返回false / true,我仍然无法通过规格测试。我是不是忘记使用CanCan匹配器? 还是存根? 或者在CanCan中定义能力?还有其他需要注意的地方吗?
ability.rb
ability.rb
class Ability
include CanCan::Ability
def initialize(user)
user ||= User.new
can :invite_to, Network do |network|
network.allows_invitations? && (user.admin? || user.can_send_invitations_for?(network))
end
end
end
ability_spec.rb
require 'cancan'
require 'cancan/matchers'
require_relative '../../app/models/ability.rb'
class Network; end;
describe Ability do
let(:ability) { Ability.new(@user) }
describe "#invite_to, Network" do
context "when network level invitations are enabled" do
let(:network) { stub(allows_invitations?: true) }
it "allows an admin" do
@user = stub(admin?: true)
ability.should be_able_to(:invite_to, network)
end
it "allows a member if the member's invitation privileges are enabled" do
@user = stub(admin?: false, can_send_invitations_for?: true)
ability.should be_able_to(:invite_to, network)
end
it "denies a member if the member's invitation privileges are disabled" do
@user = stub(admin?: false, can_send_invitations_for?: false)
ability.should_not be_able_to(:invite_to, network)
end
end
end
end
故障
1) Ability#invite_to, Network when network level invitations are enabled allows an admin
Failure/Error: ability.should be_able_to(:invite_to, network)
expected to be able to :invite_to #<RSpec::Mocks::Mock:0x3fe3ed90444c @name=nil>
# ./spec/models/ability_spec.rb:16:in `block (4 levels) in <top (required)>'
2) Ability#invite_to, Network when network level invitations are enabled allows a member if the member's invitation privileges are enabled
