node-time-ago/mocha-test.js

Simple time ago function for node that actually works!

// Load chai expect
const expect 	= 	require('chai').expect;
const timeAgo 	= 	require('./index');

// test results to expect
var results = {
	now				: 	"just now",
	seconds			: 	"35 second ago",
	minute 			: 	"a minute ago",
	minutes			: 	"3 minutes ago",
	hour 			: 	"an hour ago",
	hours			: 	"3 hours ago",
	day 			: 	"a day ago",
	days 			: 	"3 days ago",
	month 			: 	"a month ago",
	months 			: 	"3 months ago",
	year 			: 	"a year ago",
	years 			: 	"3 years ago"
};
