Question

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

Which returns :

1) CategoriesController GET show assigns the requested category as @category
   Failure/Error: assigns(:category).should be(mock_category)
   expected Category_1002, got nil

I’m confused here, because this is a right out of the box controller that rspec set up. Why could this be failing?

My versions:

Rails 3.0.0.beta4
Ruby 1.8.7
RSpec 2.0.0.beta.10

Also tried this, same exact reproducible error with :

Rails 3.0.0
Ruby 1.8.7
RSpec 2.0.0.beta.20

The command I used to generate the specs were rails g scaffold Category

In my application.rb

config.generators do |g|
  g.template_engine :haml
  g.test_framework :rspec, :fixture => true, :views => false
end

UPDATE

This goes for any scaffolded controller by Rails 3, with RSpec2. Its guarenteed to fail. Anyone know how this is supposed to be written?

Answer 1

The conflict comes from conflicts that occurred between Rspec Beta 10 and Rspec Beta 20, and Rails 3 Beta4, to Rails 3 release.

To solve this, I uninstalled haml, and installed haml-rails.

Then I deleted all the specs that were previously generated, and regenerated them.
