Question

I have been attempting to dive into RSpec 2 but its auto generated controller specs do not work for any version of RSpec 2 with any version of Ruby or any version of Rails. Maybe I’m missing something obvious?

def mock_category(stubs={})
  @mock_category ||= mock_model(Category, stubs).as_null_object
end

describe "GET show" do
  it "assigns the requested category as @category" do
    Category.stub(:find).with("37") { mock_category }
    get :show, :id => "37"
    assigns(:category).should be(mock_category)
  end
end

This is auto generated from rails g scaffold Category

RSpec returns this :

Failures:
   1) CategoriesController GET show assigns the requested category as @category
    Failure/Error: assigns(:category).should be(mock_category)
    expected Category_1002, got nil
    # ./spec/controllers/categories_controller_spec.rb:21
    # /Library/Ruby/Gems/1.8/gems/activesupport-3.0.0/lib/active_support/dependencies.rb:239:in `inject'

Why is this mock/stub returning nil ?

Update

This is from my controller’s show method :

def show
   @category = Category.find(params[:id])

  respond_to do |format|
    format.html # show.html.erb
    format.xml  { render :xml => @category }
  end
end

Thanks!

RSpec has some serious conflicts between Rails3 beta, and RSpec 2 beta.10 to Rails3 release, and RSpec 2 beta.20.

I tried copying and pasting the differences between the scaffolds, but I cleared up the sitation entirely by deleting all the specs, and regenerating them. Uninstalling haml, and installing only haml-rails for rails 3.

All the specs run now.
