rspec users - Oct 2007 - Examples of writing controller specs that use authentication

Hello,
I''m working on specs for a controller that handles authentication  
using the restful_authentication plugin. I''m trying to find a  
resource (tutorial or examples, if possible) about the best way to go  
about writing mocks and specs to make sure that things like my  
before_filters are working correctly. Does anyone know of any good  
resources for this?

Thanks,
Les

To make sure that the filter works when you''re not logged in, just
make the request:

describe CategoriesController, " POST /categories, not logged in" do
  it "should redirect to the login url" do
    post :create, :category => {"name" => "foo"}
    response.should redirect_to(login_url)
  end
end

and when you want to spec the meat of the request, stub the logged_in? method:

describe CategoriesController, " POST /categories" do
  before(:each) do
    controller.stub!(:logged_in?).and_return(true)
    @mock_category = mock_model(Category, :save => true)
    Category.stub!(:new).and_return(@mock_category)
  end

  def do_post
    post :create, :category => {"name" => "foo"}
  end

  it "should create a new category" do
    Category.should_receive(:new).with("name" =>
"foo").and_return(@mock_category)
    do_post
  end

  it "should save the category" do
    @mock_category.should_receive(:save).and_return(true)
    do_post
  end

  it "should redirect to the category''s url" do
    do_post
    response.should redirect_to(category_url(@mock_category))
  end
end

Or, if you need different users to behave in different ways, you  
might want to create a helper in spec_helper.rb, such as this:

   def login_as(user, options = {:id => "5", :needs_activation
=> false,
                                 :admin => false})
     user.stub!(:id).and_return(options[:id])
     user.stub!(:to_param).and_return(options[:id])
     user.stub!(:needs_activation?).and_return(options 
[:needs_activation])
     user.stub!(:admin?).and_return(options[:admin])
     controller.send :current_user=, user
   end

Then you can just say this in the specs:

login_as(@user_mock_object)

and the controller will behave accordingly (assuming you use  
restful_authentication/acts_as_authenticated).
