anonymous controller

Use the controller method to define an anonymous controller derived from
ApplicationController. This is useful for specifying behavior like global
error handling.

To specify a different base class, you can pass the class explicitly to the
controller method:

controller(BaseController)

You can also configure RSpec to use the described class:

RSpec.configure do |c|
  c.infer_base_class_for_anonymous_controllers = true
end

describe BaseController do
  controller { ... }
Scenarios
specify error handling in ApplicationController
Given
a file named "spec/controllers/application_controller_spec.rb" with:
require "spec_helper"

class ApplicationController < ActionController::Base
  class AccessDenied < StandardError; end

  rescue_from AccessDenied, :with => :access_denied

private

  def access_denied
    redirect_to "/401.html"
  end
end

describe ApplicationController do
  controller do
    def index
      raise ApplicationController::AccessDenied
    end
  end

  describe "handling AccessDenied exceptions" do
    it "redirects to the /401.html page" do
      get :index
      response.should redirect_to("/401.html")
    end
  end
end
When
I run rspec spec
Then
the examples should all pass
specify error handling in subclass of ApplicationController
Given
a file named "spec/controllers/application_controller_subclass_spec.rb" with:
require "spec_helper"

class ApplicationController < ActionController::Base
  class AccessDenied < StandardError; end
end

class ApplicationControllerSubclass < ApplicationController

  rescue_from ApplicationController::AccessDenied, :with => :access_denied

private

  def access_denied
    redirect_to "/401.html"
  end
end

describe ApplicationControllerSubclass do
  controller(ApplicationControllerSubclass) do
    def index
      raise ApplicationController::AccessDenied
    end
  end

  describe "handling AccessDenied exceptions" do
    it "redirects to the /401.html page" do
      get :index
      response.should redirect_to("/401.html")
    end
  end
end
When
I run rspec spec
Then
the examples should all pass
infer base class from the described class
Given
a file named "spec/controllers/base_class_can_be_inferred_spec.rb" with:
require "spec_helper"

RSpec.configure do |c|
  c.infer_base_class_for_anonymous_controllers = true
end

class ApplicationController < ActionController::Base; end

class ApplicationControllerSubclass < ApplicationController; end

describe ApplicationControllerSubclass do
  controller do
    def index
      render :text => "Hello World"
    end
  end

  it "creates an anonymous controller derived from ApplicationControllerSubclass" do
    controller.should be_a_kind_of(ApplicationControllerSubclass)
  end
end
When
I run rspec spec
Then
the examples should all pass
invoke around filter in base class
Given
a file named "spec/controllers/application_controller_around_filter_spec.rb" with:
require "spec_helper"

class ApplicationController < ActionController::Base
  around_filter :an_around_filter

  def an_around_filter
    @callback_invoked = true
    yield
  end
end

describe ApplicationController do
  controller do
    def index
      render :nothing => true
    end
  end

  it "invokes the callback" do
    get :index

    assigns[:callback_invoked].should be_true
  end
end
When
I run rspec spec
Then
the examples should all pass
