fractal-transformer/test/index.js

Transform data for presentation and transformation layer for complex data output, the like found in RESTful APIs, and works really well with JSON. Its like a view layer for your JSON/YAML/etc.

var should = require('chai').should();
var fractal = require('../index')({
    transformerDir: 'test/transformers',
