to be between

<moment> [not] to be [inclusively] between <moment|string|number|date|array|object> <moment|string|number|date|array|object>

Passes if the moment instance is between two other given instances:

expect(moment(), 'to be between', moment().startOf('day'), moment().endOf('day'))

To include the end-points as valid values, use

expect(moment(0), 'to be inclusively between', moment(0), moment(10))

Failing assertions gives the following:

expect(moment('2015-01-01'), 'to be between', moment('2015-02-01'), moment('2015-03-01'));

expected moment('2015-01-01T00:00:00.000+01:00')

to be between moment('2015-02-01T00:00:00.000+01:00') and moment('2015-03-01T00:00:00.000+01:00')
