Controller specs

Controller specs live in spec/controllers or any example group with
:type => :controller.

A controller spec is an RSpec wrapper for a Rails functional test
(ActionController::TestCase::Behavior).
It allows you to simulate a single http request in each example, and then
specify expected outcomes such as:

rendered templates
redirects
instance variables assigned in the controller to be shared with the view
cookies sent back with the response

To specify outcomes, you can use:

standard rspec matchers (expect(response.status).to eq(200))
standard test/unit assertions (assert_equal 200, response.status)
rails assertions (assert_response 200)
rails-specific matchers:
- expect(response).to render_template(wraps assert_template)
- expect(response).to redirect_to(wraps assert_redirected_to)
- expect(assigns(:widget)).to be_a_new(Widget)

Examples

describe TeamsController do
  describe "GET index" do
    it "assigns @teams" do
      team = Team.create
      get :index
      expect(assigns(:teams)).to eq([team])
    end

    it "renders the index template" do
      get :index
      expect(response).to render_template("index")
    end
  end
end

Views

by default, views are not rendered. See views are stubbed by default and render_views for details.
