chai-moment 

Matchers for dates and formatted date strings powered by moment.js

Using

Also see the tests and examples.

$3

include chai moment after chai and moment:

$3

have chai use chai-moment:

``javascript

var chai = require('chai');
chai.use(require('chai-moment'));

`

Assertions

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.

`javascript

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');

// using expect-style assertions
expect(milliseconds).to.be.sameMoment(obj);
expect(dateString).to.be.sameMoment(oneDayLater, 'month');

// using tdd assertions
assert.sameMoment(arr, momentObj);
assert.sameMoment(arr, oneDayLater, 'month');
assert.sameMoment(arr, oneDayLater, 'month', 'custom error message');
assert.sameMoment(arr, oneDayLater, 'custom error message'); // fails

`

`javascript

var dateString = '2016-04-21',
oneDayLater = '2016-04-22';

// using should-style assertions
dateString.should.be.beforeMoment(oneDayLater);
dateString.should.be.beforeMoment(oneDayLater, 'month'); // fails

// using expect-style assertions
expect(dateString).to.be.beforeMoment(oneDayLater);
expect(dateString).to.be.beforeMoment(oneDayLater, 'month'); // fails

// using tdd assertions
assert.beforeMoment(dateString, oneDayLater);
assert.beforeMoment(dateString, oneDayLater, 'month'); // fails
assert.beforeMoment(dateString, oneDayLater, 'month', 'custom error message'); // fails
assert.beforeMoment(dateString, oneDayLater, 'custom error message');

`

$3

`javascript

var dateString = '2016-04-21',
oneDayLater = '2016-04-22';

// using should-style assertions
oneDayLater.should.be.afterMoment(dateString);
oneDayLater.should.be.afterMoment(dateString, 'month'); // fails

// using expect-style assertions
expect(oneDayLater).to.be.afterMoment(dateString);
expect(oneDayLater).to.be.afterMoment(dateString, 'month'); // fails

// using tdd assertions
assert.afterMoment(oneDayLater, dateString);
assert.afterMoment(oneDayLater, dateString, 'month'); // fails
assert.afterMoment(oneDayLater, dateString, 'month', 'custom error message'); // fails
assert.afterMoment(oneDayLater, dateString, 'custom error message');

`

Configuration

$3

Sets the format used for reporting moments in failed assertions.

`javascript

var chaiMoment = require('chai-moment');

chaiMoment.setErrorFormat('L');

expect(moment('2016-04-21')).to.be.beforeMoment(moment('2016-04-22'));
// Error('expected 04/21/2017 to be before 04/22/2016')
