Adds several handy expectations for testing ActiveRecord model validations.

== Dependencies

Depends on validation_reflection plugin:

  script/plugin install git://github.com/redinger/validation_reflection.git

== Installation

Install the gem directly:

  gem sources -a http://gems.github.com (you only have to do this once)
  sudo gem install pelargir-rspec_validation_expectations
  
Or install the gem in your Rails project:
  
  gem sources -a http://gems.github.com
  script/plugin install pelargir-rspec_validation_expectations

Or clone the project:

  git clone git://github.com/pelargir/rspec_validation_expectations.git

== Usage

Ensure that validations and assocations are properly defined in your models:

  describe User do
    it_should_validate_presence_of     :first_name, :last_name, :email
    it_should_validate_numericality_of :zip
    it_should_validate_uniqueness_of   :email
    it_should_validate_inclusion_of    :gender, :in => %w(Male Female)
    
    # tests that User.count increases by 1
    it_should_be_createable :with => {:first_name => 'Ed', :last_name => 'The Duck', :email => 'a@b.com'}
    
    it_should_belong_to :employer
    it_should_have_many :friends, :romans, :countrymen
    it_should_have_one  :account
    it_should_have_and_belong_to_many :comments
  end
  
Which gives you:

ruby script/spec --format s spec/models/user_spec.rb:

User
- should validate presence of first name
- should validate presence of last name
- should validate presence of email
- should validate numericality of zip
- should validate uniqueness of email
- should validate inclusion of gender as one of Male or Female
- should be creatable
- should belong to employer
- should have many friends
- should have many romans
- should have many countrymen
- should have one account
- should have and belong to many comments
