The Ultimate Unit Testing Cheat-sheet

Shutdown your VM and do:

VirtualBox > Settings > Network > Add (you will get vboxnet0)

On a terminal ifconfig will show you new interface vboxnet0

VM's Settings > System > check "Enable I/O APIC." VM's Settings > Network > Adapter 2 > host-only vboxnet0

	import renderer from 'react-test-renderer'
	import Viewport from '../Viewport'

	it('should render correctly', () => {
	const target = {
	innerHeight: 600,
	innerWidth: 800,
	addEventListener: jest.fn(),
	removeEventListener: jest.fn()
	}

	Add the `replication` section to the mongod.conf file:

	```
	$cat /usr/local/etc/mongod.conf
	systemLog:
	destination: file
	path: /usr/local/var/log/mongodb/mongo.log
	logAppend: true
	storage:
	engine: mmapv1

	import { mountWithIntl } from 'helpers/intl-enzyme-test-helper.js';

	const wrapper = mountWithIntl(
	<CustomComponent />
	);

	expect(wrapper.state('foo')).to.equal('bar'); // OK
	expect(wrapper.text()).to.equal('Hello World!'); // OK

	// Allows:
	// funkyParser()

	module.exports = function createFunkyParser(opt) {
	return new FunkyParser(opt)
	}

	function FunkyParser(opt) {
	// make params optional
	opt = opt \|\| {}

	var a = 123, b = 'hello';
	function test(x, y) {
	console.log(this);
	return a + x + b + y;
	}

	// Serialize a function with its captured environment
	var sf = serialize(test, { a: a, b: b });

	// Deserialize with captured environment
