Hi,
I am a newbie to Rails 3 and Rspec. Kindly excuse my being a novice. I am trying to implement RSpec with Rails 3. I am using Rails 3.0.3 with Ruby 1.9.2 on Ubuntu 10.04 os. I am using rspec 2.5 gem and rspec-rails 2.5 gem. I am referring to the following tutorial:- http://www.railsfire.com/article/rspec-behaviour-driven-development-testing-framework This tutorial is implemented on Rails 2.x with an older version of rspec and rspec-rails. I tried to implement ***exactly the same tutorial*** with my configuration, but I have run into some issues. I am unable to figure out what I must have done wrong. I am sure about one thing that I am not using the `rails_scaffold` generator as used in this tutorial. Instead of using the `rails_scaffold` generator, I made use of the following command `rails g scaffold post title:string body:text` I don't seem to have it(rspec_scaffold) in my list of generators which as part of Rails 3 and the additional ones that will come with Rspec. The error I am getting is :- mohnish@mohnish-desktop:~/rails_testing/10Mar11/rspec_demo5$ rake spec (in /home/mohnish/rails_testing/10Mar11/rspec_demo5) rake aborted! You have a nil object when you didn't expect it! You might have expected an instance of ActiveRecord::Base.
