# Usage:  startJsTester
#
# This starts karma, the javascript unit test framework.  This script
# is meant to be run on a development machine.  It will launch Chrome
# and execute all javascript unit tests, reporting the results to
# stdout.  By default, the script will never terminate, but instead watch
# for changes to any of the monitored javascript files and HTML resources
# (defined in a configuration file), rerunning all unit tests with each new
# change and reporting the results to stdout.
#
# The unit test framework also runs a light weight http server on
# port 9876 allowing you to access local files over http, enabling
# direct testing of some of the html files.  This is better than just
# using the browser to access the files via file:// because the browser's
# default security policies prevents javascript loaded via file:// to
# load other javascript files.
#
# To use this script, you must have installed node.js and karma.
# To install karma, do the following:
# 1. Download the node.js pkg file from http://nodejs.org and follow instructions.
# 2. sudo npm install -g karma karma-jasmine karma-chrome-launcher

# The karma configuration file, which details configures which js files
# are included, how to run http server and what files to export, etc,
# is in scripts/includeFiles/karma.conf.js
