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 assertAlmostEqual 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; it does a deep comparison; it can not handle cycles in the data structure.
