Mockment

Description

Mockment is a small library of functions supposed to facilitate testing code using the moment library.
Specifically mockment helps you to test code which uses moment() or moment.now().

Installation

Install mockment with

npm i -D mockment

Usage

mockment exposes the following functions.

The following function manipulate how moment determines the current time, each of them accepting a single parameter that can either be a time in milliseconds sice Unix epoch, an object of type Date or an object of type Moment

• setNowBeforeEach
  This function sets moment's current time globally to the passed time. By default, the current time is set to Date.now() before each test execution.

• setNowTo
  This function immediately sets the current time to the passed time. This function can be used to change the current time within the execution of a test.

• startNowFrom
  This function bases the current time of the passed value. Moment will resolve the current time as the passed value plus the time elapsed since the base was set.

The current time behavior can be reset to its original behavior using resetAll
