object-key-mirror/test/index.test.js

Object key mirror is a zero-dependency Node.js module that lets you easily create objects with values equal to their key names.

var expect = require('chai').expect;
import objectKeyMirror from '../src/index';


describe('objectKeyMirror', function() {
  it('should return an object when an array supplied', function() {
      expect(objectKeyMirror(['LOGIN_SUCCESS']))
        .to.be.an('object');

        .to.deep.equal({ LOGIN_SUCCESS: 'LOGIN_SUCCESS',SIGNUP_SUCCESS: 'SIGNUP_SUCCESS', LOGIN_FAILURE: 'LOGIN_FAILURE' });

      expect(objectKeyMirror(['LOGIN_SUCCESS'])).to.deep
      .equal({ LOGIN_SUCCESS: 'LOGIN_SUCCESS' });
