factory-boy v0.0.5

Factory Boy

Factory Boy is an library for Node.js which provides factories for objects creation. It's highly inspired by the fabolous factory_girl library for Ruby on Rails.

It comes with support for :

• lazy attributes
• defining factory initialization and creation methods

Installation

npm install factory-boy

Defining factories

Factory = require('factory-boy').Factory

Factory.define 'user', class: User, ->
  @first_name = 'John'
  @last_name = 'Smith'
  @pin = (callback) -> callback(null, Math.floor(Math.random()*10000))
  
  
Factory.build 'user', (err, user) ->
  console.log user


Factory.create 'user', (err, user) ->
  console.log user

Lazy attributes

Attributes defined by functions are evaluated upon object intialization/creation. Lazy functions context are set to factory instance so it's possible to use already defined attributes.

Factory.define 'user', class: User, ->
  @first_name = 'John'
  @salt = (callback) -> 
    time = new Date()
    callback(null, "@{first_name}#{time}")

Additionally lazy functions are evaluated in the defined order.

Factory.define 'user', class: User, ->
  @number1 = (callback) -> callback(null, 10)
  @number2 = (callback) -> callback(null, @number1 + 10)
