How to use the serialport/test.Binding function in serialport

/* eslint-disable node/no-missing-require */

// Load Serialport with mock bindings
// const SerialPort = require('../test'); // from inside the serialport repo
const SerialPort = require('serialport/test') // when installed as a package
const MockBinding = SerialPort.Binding

const portPath = 'COM_ANYTHING'

// The mock bindings can pretend to be an arduino with the `arduinoEcho` program loaded.
// This will echo any byte written to the port and will emit "READY" data after opening.
// You enable this by passing `echo: true`

// Another additional option is `record`, if `record: true` is present all
// writes will be recorded into a single buffer for the lifetime of the port
// it can be read from `port.binding.recording`.

// Create a port
MockBinding.createPort(portPath, { echo: false, record: false })

const port = new SerialPort(portPath)
port.on('open', () => {

'use strict';

var Insteon = require('../').Insteon;
var should = require('should');

var SerialPort = require('serialport/test');
var MockBinding = SerialPort.Binding;
MockBinding.createPort('/dev/home-controller-mock', { echo: false, record: true, readyData: '' });

var mockSerial = require('../lib/Test/mockSerial');
var Plan = require('../lib/Test/Plan');
