Description:

Contextually is a gem for running Rails controller tests under different user contexts in a convenient way. So you can test your authorization without much effort.

Synopsis:

Somewhere sensible (like your spec helper file), define your contexts like this:

    Contextually.define do
      roles :user, :visitor, :monkey

      group :user, :monkey, :as => :member
      group :visitor, :monkey, :as => :idiot

      before :user do
        controller.stub!(:current_user).and_return(:user)
      end
      before :visitor do
        controller.stub!(:current_user).and_return(nil)
      end
      before :monkey do
        controller.stub!(:current_user).and_return(:monkey)
      end

      deny_access_to :visitor do
        it("should deny access") { should redirect_to(new_session_url) }
      end
      deny_access do
        it("should deny access") { should redirect_to(root_url) }
      end
    end

Then use them in your controller specs like this:

    describe TestsController do
      as :user, :get => :index do
        it { should respond_with(:success) }
      end

      as :visitor, :get => :index do
        it("should deny access") { should redirect_to(new_session_url) }
      end

      as :visitor, :monkey, :user, :get => :show do
        it { should respond_with(:success) }
      end

      as :visitor, :monkey, :user, "GET /test" do
        describe :get => :show do
          it { should respond_with(:success) }
        end
      end

      as :visitor, :monkey, :user do
        describe :get => :show do
          it { should respond_with(:success) }
        end
      end

      only_as :user, :get => :index do
        it { should respond_with(:success) }
      end

      deny_access_to :monkey, :visitor, :get => :index

      deny_access_to :idiot, :get => :index

      only_as :member, :get => :foo do
        it { should respond_with(:success) }
      end
    end
