rspec_validation_expectations

Adds several handy expectations for testing ActiveRecord model validations and associations.

Dependencies

Requires the validation_reflection plugin:

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

Installation

Install the gem directly:

sudo gem install pelargir-rspec_validation_expectations --source=http://gems.github.com

Or install the gem in your Rails project:

script/plugin install git://github.com/pelargir/rspec_validation_expectations.git

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

  # tests that the attribute is protected
  it_should_protect :email
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
- should protect email
