 - Refactor unit tests into sets of related assertions.
 - Refactor all unit tests to use the new recommend exception testing pattern as the current `setExpectedException()` method is deprecated.
-- Maybe refactor names to be isXxx - maybe - but probably too much BC issues. Aliases are an option for BC (separate function library).
-  Not really sure of the mileage on this. May simply not be worth it for the sake of consistent naming.
 - Separate assertions into sets that deal with related themes:
   - Variable type (isInt, isString isBoolean, isArray, etc.)
   - Variable content (min, max, between, etc.)
