For regressionTest:
lfs (Tested with 1.4.1)
For lunit-tests:
lunit >= 0.4
Lua versions tested recently:
Lua 5.1.4 + strict + pl.strict
Lua 5.2.0 + pl.strict
LuaJIT-2.0.0-beta10 + strict + pl.strict

Module/Function overview:
json.encode (callable module referencing json.encode.encode)
--encode ( value : ANY-valid )
Takes in a JSON-encodable value and returns the JSON-encoded text
Valid input types:
array-like table (spec below)
'null' - represented by json.util.null
Table keys (string,number,boolean) are encoded as strings, others are erroneus
Table values are any valid input-type
Array-like tables are converted into JSON arrays...
Position 1 maps to JSON Array position 0
--isEncodable ( value : ANY )
Returns a boolean stating whether is is encodeable or not
NOTE: Tables/arrays are not deeply inspected
json.decode (callable module referencing json.decode.decode)
--decode (data : string, strict : optional boolean)
Takes in a string of JSON data and converts it into a Lua object
If 'strict' is set, then the strict JSON rule-set is used
--printValue (tab : ANY, name : string)
recursively prints out all object values - if duplicates found, reference printed
Reference value to represent 'null' in a well-defined way to
allow for null values to be inserted into an array/table
