No such factory: user

end

spec/spec_helper.rb

ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)

Answer 1

Do you have the following lines in your config\application.rb:

# Configure generators values.
config.generators do |g|
  g.test_framework  :rspec, :fixture => true
  g.fixture_replacement :factory_girl, :dir=>"spec/factories"
end

Answer 2

Add the 'factory_girl_rails" gem to your Gemfile under your :test, :development groups, as follows:

group :development, :test do
   gem 'webrat'
   gem "cucumber-rails"
   gem "rspec-rails"
   gem "rspec"
   gem "autotest"
   gem 'factory_girl'
   gem 'factory_girl_rails'
end

In Rails 3, you need to add that gem to make it work. Hope it helps.
