A 'chaos monkey'-style mischief maker that operates on the client
Chaos Monkey is an idea originally outlined by the Netflix tech team.
The basic idea is to have something in your stack that causes random failures in your system, so you’ll be forced to make your app resilient against random failure.
chaos-monkey-browser is failure module that installs entirely on the client. This is particularly useful for apps that use multiple backends or when developers don't have an easy method for modifying a remote dependency.
Inspired by Chaos Monkeyware
The failure propability is configurable (0.0 - 1.0 with 1.0 equal to 100%). The default is 0.1.
The currently included failure modes (called mischiefs) are:
Currently, all of these mischiefs have equal propability. Mischiefs can be enabled independently by passing in only the desired mischiefs.
By default, all methods [GET,POST,PUT,DELETE] allow failure. Methods can be enabled independently by passing in only the desired methods.
chaos-monkey-browser is AMD-aware. It can be used with or without require.js.

chaos-monkey-browser works by overriding the jquery ajax call. Consequently, jquery is required. Asynchronous http calls that call the browser XMLHttpRequest API directly will not be intercepted.
