why this custom msg? assertEqual() already prints out the expected and actual
values?

[conleyo, 2015/08/04 18:53:55]

Sorry, debugging output.  The standard string diff message is practically
worthless.  In my personal python projects I always override assertEqual with a
more descriptive method.

[conleyo, 2015/08/04 22:56:14]

Done.
