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

Examples

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

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

Views

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