CanCan Ability Spec

ability_spec.rb

require 'spec_helper'

describe Ability do
  let(:admin_user) { mock AdminUser }

  it { Ability.should include(CanCan::Ability) }
  it { Ability.should respond_to(:new).with(1).argument }

  context "admin" do
    before :each do
      admin_user.stub!(:role).and_return("admin")
    end

    it "can manage all" do
      Ability.any_instance.should_receive(:can).with(:manage, :all)

      Ability.new admin_user
    end
  end

  context "editor" do
    before :each do
      admin_user.stub!(:role).and_return("editor")
    end

    it "can not manage all" do
      Ability.any_instance.should_not_receive(:can).with(:manage, :all)

      Ability.new admin_user
    end

    it "can create and edit models" do
     [Thing, Widget].each do |model|
       Ability.any_instance.should_receive(:can).with([:read, :update], model)
     end
     Ability.new admin_user
   end
  end
end

I get this output when I try to use should_receive:

undefined method `should_receive' for Ability:Class (NoMethodError)

@atomical It sounds like you don't have rspec loaded correctly

At the top:
require 'spec_helper'
require "cancan/matchers"

Would it be a matcher?

.should_receive is a method from rspec-expectations.

Honestly the code above is probably not the best way to do this. Take a look here: https://github.com/ryanb/cancan/wiki/Testing-Abilities

I'm writing a test to make sure a special form of current_user is passed in. Basically testing to make sure the right arguments are passed in in current_ability in the application controller.

Updated the gist with our latest code. I think .any_instance will solve the problem you were having. Hope this helps.

Thanks!
