Fabricate real objects with fake data

Fabrication

Construct real Objects with fake data

Fabrication allows you to build fabricators that produce real objects from your codebase using fake data. It provides several aids to ease the process of populating Objects.

var userFabricator = fabrication.fabricator(function() {
  return new User(
    this.sequence('User').next,
    this.generate.name(),
    this.generate.email()
  );
});
 
var fakeUser = userFabricator();
// fakeUser => { id: 1, name: 'Arthur Dent', email: 'guide@galaxy.net' }

The fabrication module and it's API has three parts:

  1. fabricate
  2. generate
  3. sequence

Fabrication facilitates in generating random data to populate Objects easilly. These generators are available through the generate module.

Fabrication uses grand to provide most of the generators.

var generate = require('fabrication').generate;
 
// fabrication generators 
generate.version(sections)       // A random, semver compatible version consisting of 1 or more sections (optional) 
generate.ObjectId()              // A time based ObjectId 
 
// grand generators 
generate.number(exclusiveMax)    // A random, positive number less than the exclusiveMax (optional) 
generate.integer(exclusiveMax)   // A random, positive integer less than the exclusiveMax (optional) 
generate.pick(array)             // A random item from the given array 
generate.letter()                // A random letter [A-Za-z] 
generate.wordChar()              // A random word character [A-Za-z0-9_] 
generate.word(length)            // A random word from the system dictionary of the given length (optional) 
generate.sentence(maxWords)      // A random sentence with the given number of words (optional) 
generate.gender()                // Either "male" or "female" 
generate.givenName(gender)       // A random given name for the given gender (optional) 
generate.familyName()            // A random family name 
generate.name(gender)            // A random full name of the given gender (optional) 
generate.emailAddress()          // A random email address 
generate.language(base)          // A random language and region for a given language (optional) 
generate.timezone(continent)     // A random timezone on a continent (optional) 
generate.uuid()                  // A random uuid (v4) using node-uuid and accepting the v4 parameters (optional) 

All generators are available as separate functions but the generator module is a function itself that can be used to call generators:

var generate = require('fabrication').generate;
 
var name = generate('name');
// instead of generate.name() 
 
var timezone = generate('timezone', 'Europe');
// instead of generate.timezone('Europe')
