Mo' Testing
===========

``FuzzyTestCase`` extends the ``unittest.TestCase`` to provide deep, yet
fuzzy, structural comparisons; intended for use in test cases dealing
with JSON.

Details
-------

The primary method is the ``assertEqual`` method with the following
parameters:

-  ``test_value`` - the value, or structure being tested
-  ``expected`` - the expected value or structure. In the case of a
   number, the accuracy is controlled by the following parameters. In
   the case of a structure, only the not-null parameters of ``expected``
   are tested for existence.
-  ``msg`` - Detailed error message if there is no match
-  ``digits`` - number of decimal places of accuracy required to
   consider two values equal
-  ``places`` - number of significant digits used to compare values for
   accuracy
-  ``delta`` - maximum difference between values for them to be equal

This method, ``assertEqual`` is recursive, so it does a deep comparison,
and can not handle loops.
