to be the end of

Passes if the moment instance represents the end of a unit of time.

expect(moment('2015-01-01 23:59:59.999'), 'to be the end of day');

It supports end-of-time units that are supported by moment#endOf.

When the assertion fails you'll get this output:

expect(moment('2015-01-01 00:00:00'), 'to be the end of day');
expected moment('2015-01-01T00:00:00.000+01:00') to be the end of day
