Jasmine date mocking with moment.js

Check out how moment mock dates themselves in their own test suite: https://github.com/moment/moment/blob/2e2a5b35439665d4b0200143d808a7c26d6cd30f/src/test/moment/now.js#L15

jasmine.clock().mockDate expects Date as input. Date and moment are not fully compatible. If you provide the to-be-mocked date in the spec itself you could simply use Date there instead.

If your code generates a moment you want to mock, or you'd rather use the moment API, take a look at moment.toDate(). This method returns the Date object backing a moment.

it('uses the mocked time with moment', function() {
    var today = moment('2015-10-19').toDate();
    jasmine.clock().mockDate(today);
    expect(moment().valueOf()).toEqual(today.valueOf());
});
