all callbacks use result object
custom commands, page object/section commands have same behavior/interface
client/api property consistency
better separation of user-defined apis and internal properties (page objects etc)
page/section objects have full api surface
Page objects, commands classes, having proper instanceof-checkable instances (no weird F() constructor)
Support command overrides rather than throwing an error
no legacy stuff
- afterEach hook can receive the browser object only in its async form
async behavior consistency/clarity

When attempting to build the awesome serialport NPM package in Docker using a node alpine image, in usually failes on building the node-gyp package.

There are various workarounds which can be found online, such as this one.

However, the key ingredient is building the serialport package from source, using this line:

npm install serialport --build-from-source=serialport

First, install homebrew.

To build and install cffi follow these steps:

	var chromedriver = require('chromedriver');
	var moduleFolder = '../../node_modules/chromedriver/lib/chromedriver/';
	var path = require('path');
	var binPath = path.resolve(path.join(moduleFolder, process.platform === 'win32' ? 'chromedriver.exe' : 'chromedriver'));

	module.exports = {
	defaultInstance : null,

	start : function() {
	this.defaultInstance = require('child_process').execFile(binPath, [

	module.exports = {
	groupGlobals : null,

	checkGroupGlobals : function(hookName) {
	if (hookName && this.groupGlobals) {
	return this.groupGlobals[hookName];
	}

	if (this.test_settings.group_name) {
	try {

	exports.assertion = function(selector) {
	this.selector = selector;
	this.message = 'Testing if element <' + selector + '> has no descendents.';
	this.expected = true;

	this.pass = function(value) {
	return value && (value.length === 0);
	};

	this.value = function(result) {
