Testing and cancan in controller specifications (rspec)

Now that I am working with CanCan and Devise, I need to add my tests.

Should I count on doubling the number of tests, maybe more? I need to check everything as a "guest", and then check as a user as well as an administrator.

With rspec, how would you formulate this?

describe "GET edit" do
    login_admin
    it "assigns the requested forum_topic as @forum_topic" do
      ForumTopic.stub(:find).with("37") { mock_forum_topic }
      get :edit, :id => "37"
      response.should redirect_to( new_user_session_path )
    end

    it "assigns the requested forum_topic as @forum_topic" do
      ForumTopic.stub(:find).with("37") { mock_forum_topic }
      get :edit, :id => "37"
      assigns(:forum_topic).should be(mock_forum_topic)
    end
end

auxiliary module

  def login_admin
    before(:each) do
      @request.env["devise.mapping"] = Devise.mappings[:admin]
      sign_in Factory.create(:admin)
    end
  end

  def login_user
    before(:each) do
      @request.env["devise.mapping"] = Devise.mappings[:user]
      @user = Factory.create(:user)
      sign_in @user
    end
  end

What is usually done when testing CanCan, he tests the capabilities file himself.

For example, if you test that in your application you will not be able to view a specific forum if you are not subscribed, you can check it like this:

@user = Factory.create(:user)
@forum = Factory.create(:forum)

describe "User ability" do
  it "Should be able to view forums" do
    @ability = Ability.new(@user)
    @ability.should be_able_to(:show, @forum)
  end
end

describe "nil ability" do
  it "Should be not be able to view forums if not signed in" do
    @ability = Ability.new(nil)
    @ability.should_not be_able_to(:show, @forum)
  end
end

This is just an example.
