How to use the sharp.prototype function in sharp

// Strict mode.
'use strict'

// Package modules.
const sharp = require('sharp')
const sinon = require('sinon')

// Configure.
const methods = Object.getOwnPropertyNames(sharp.prototype)

// Patch methods, add reset and restore handlers.
methods.forEach((name) => sinon.spy(sharp.prototype, name))
sharp.prototype.reset = () => {
  methods.forEach((name) => sharp.prototype[name].resetHistory())
}
sharp.prototype.restore = () => {
  methods.forEach((name) => sharp.prototype[name].restore())
}
