Matchers for dates and formatted date strings powered by moment.js
Also see the tests and examples.
include chai moment after chai and moment:
<script src="moment.js"></script>
<script src="chai.js"></script>
<script src="chai-moment.js"></script>
have chai use chai-moment:
var chai = require('chai');
chai.use(require('chai-moment'));
Compare any moment-parseable date/string/whatever with another, with optional granularity. See Moment.js docs on parsing.
When using granularity, please use one of the following: year, month, week, day, hour, minute, second. When using tdd-style assertions, if you do not use one of the listed granularities, the argument will be interpreted as a custom error message.
var dateString = '2016-04-21',
date = new Date(2016, 3, 21),
milliseconds = 1461222000000, // assumes system has PDT timezone
obj = { y: 2016, M: 3, d: 21 },
arr = [2016, 3, 21],
momentObj = moment('2016-04-21'),
oneDayLater = '2016-04-22';
// using should-style assertions
dateString.should.be.sameMoment(date);
dateString.should.be.sameMoment(oneDayLater, 'month');
