Need Help : Trying to write unit test in Javascript

[GauravKatariya]

Hi,
The library looks very promising for mocking Xrm .
I am trying to write unit test using jest but "XrmMockGenerator.initialise()" is giving undefined.

Sample code.
var XrmMockGenerator = require('xrm-mock');

test('trying xrm-mock', () => {
var Xrm = XrmMockGenerator.initialise();

});
