Re: New assertEquals() for Beans

Having faced a similar problem in the past we created a Hamcrest matcher to
do deep object comparisons for us.  Internally it serializes to json to do
the actual comparison.

You can read why we wrote it and how to use it here:
http://tech.shazam.com/server/easing-matcher-creation-with-shazamcrest/
Or get it from github here: https://github.com/shazam/shazamcrest

One of the real benefits of using Json is that running tests in your IDE
can make use of the "click to see difference" feature to get an easy to
read view of what was different.

Maybe she awoke to see the roommate's boyfriend swinging from the
chandelier wearing a boar's head.

Something which you, I, and everyone else would call "Tuesday", of course.
