Install

Mac OS X

Using Homebrew (yes, I am opinionated) you can install the following tools with the following packages:

	#!/bin/bash
	#
	# Remixed from https://gist.github.com/nicerobot/1443588
	#
	# Usage:
	# * export-chrome-cookie.sh
	# * export-chrome-cookie.sh <domain>
	# <domain> examples:
	# .google.com
	# %.google.com (SQLite wildcard)

	#Model

	@user.should have(1).error_on(:username) # Checks whether there is an error in username
	@user.errors[:username].should include("can't be blank") # check for the error message

	#Rendering
	response.should render_template(:index)

	#Redirecting
	response.should redirect_to(movies_path)

	sqlite3 -separator ' ' ${COOKIES:-Cookies} \
	'select host_key, "TRUE", path, "FALSE", expires_utc, name, value from cookies'
