A test for a module performing trivial transformation on data from an external service:

it('returns the first element in the response', function () {
  var serviceResponse = [{a: 1}]
  serviceStub.returns(serviceResponse)
  
  expect(subject()).to.equal(serviceResponse[0])
})

Creating an array where under some conditions we include extra pairs of values.

var mysqlArgs = ['-h', mysqlConfig.host, '-d', mysqlConfig.database];

if (mysqlConfig.user) {
  mysqlArgs.push('-U', mysqlConfig.user);
}

	var app = require('express')()
	, server = require('http').createServer(app)

	app.use(function (req, res, next) {
	console.log('Handling', req.path, process.pid)

	var d = require('domain').create()
	d.add(req)
	d.add(res)

	var when = require('when')

	// An array of promises that must resolve before we can submit
	var preSubmitActions = []

	function loadSomeScript() {
	// An example use case. We want to delay the submit until
	// some script has loaded. We start loading the script in postRender
	// so it may or may not be finished by the time someone clicks submit

	var cookie = require('cookie')

	module.exports.forRequest = function (req) {
	return {
	get: function (name) { return req.cookies[name] },
	set: function (name, value, options) {
	req.res.cookie(name, value, options)
	}
	}
	}
