Better Jasmine Tests With `this`

On the Refinery29 Mobile Web Team, codenamed "Bicycle", all of our unit tests are written using Jasmine, an awesome BDD library written by Pivotal Labs. We recently switched how we set up data for tests from declaring and assigning to closures, to assigning properties to each test case's this object, and we've seen some awesome benefits from doing such.

The old way

Up until recently, a typical unit test for us looked something like this:

describe('views.Card', function() {

Provider	Singleton	Instantiable	Configurable
Constant	Yes	No	No
Value	Yes	No	No
Service	Yes	No	No
Factory	Yes	Yes	No
Decorator	Yes	No?	No
Provider	Yes	Yes	Yes

OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

	#https://gorails.com/setup/ubuntu/14.04
	sudo apt-get update
	sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties
	sudo apt-get install libgdbm-dev libncurses5-dev automake libtool bison libffi-dev

	curl -L https://get.rvm.io \| bash -s stable
	source ~/.rvm/scripts/rvm
	echo "source ~/.rvm/scripts/rvm" >> ~/.bashrc
	rvm install 2.1.2
	rvm use 2.1.2 --default

	// === Arrays

	var [a, b] = [1, 2];
	console.log(a, b);
	//=> 1 2


	// Use from functions, only select from pattern
	var foo = () => [1, 2, 3];

	function Foo(who) {
	this.me = who;
	}

	Foo.prototype.identify = function() {
	return "I am " + this.me;
	};

	function Bar(who) {
	Foo.call(this,"Bar:" + who);

	# put this in your .bash_profile
	if [ $ITERM_SESSION_ID ]; then
	export PROMPT_COMMAND='echo -ne "\033];${PWD##*/}\007"; ':"$PROMPT_COMMAND";
	fi

	# Piece-by-Piece Explanation:
	# the if condition makes sure we only screw with $PROMPT_COMMAND if we're in an iTerm environment
	# iTerm happens to give each session a unique $ITERM_SESSION_ID we can use, $ITERM_PROFILE is an option too
	# the $PROMPT_COMMAND environment variable is executed every time a command is run
