RVM, Rails 3.1rc, RSpec 2.6.0

These are steps i’ve found to work for me on Mac OSX.

rvm list
# will show you all Rubies installed in your current system, we have nothing because nothing has been installed
 
# if you haven't installed ruby 1.9.2
rvm install ruby-1.9.2-p180
# this will install Ruby 1.9.2 p180
 
rvm gemset create ruby-1.9.2-p180@rails31rc
 
rvm use ruby-1.9.2-p180@rails31rc
 
gem install rails -v ">=3.1.0rc"
 
rails new testproject -T
# -T means don't configure it with Test:Unit
 
cd testproject
 
# creates the .rvmrc file don't need echo 
rvm --rvmrc use ruby-1.9.2-p180@rails31rc
 
vi Gemfile

Gemfile

# in Gemfile
 
group :development, :test do
  gem 'database_cleaner'
  gem 'rails3-generators'
  gem 'rspec-rails'
  gem 'factory_girl_rails'
end

Install Bundle

bundle install

Configure generators

vi config/application.rb

This is inside

module Testproject
class Application < Rails::Application
# this stuff goes in here.
end
end

config/application.rb file

# in config/application.rb
 
config.generators do |g|
  # :views => false skips view spec generation
  g.test_framework :rspec, :views => false, :fixture => true
  g.fixture_replacement :factory_girl, :dir => 'spec/factories'
end

turn on autoloading of lib and sub directories

# in config/application.rb
 
config.autoload_paths += %W(#{config.root}/lib)
config.autoload_paths += Dir["#{config.root}/lib/**/"]

install for rspec

rails g rspec:install

run db:migrate

rake db:migrate

a test scaffold

rails g scaffold Email email:string

run db:migrate

rake db:migrate

run specs

rake spec
