Extreme Negative Numbers In Decimals

ItemDescription
Full Fuzzer NameExtremeNegativeNumbersInDecimalFieldsFuzzer
Log KeyENNIDF
DescriptionThis fuzzer will send outside the range values in decimal fields. The expectation is that APIs will reject the request as invalid as they might potentially break downstream systems. Furthermore, APIs should update their specs to define clear boundaries (minimum, maximum) for these fields.
Enabled by default?Yes
Target field typesOpenAPI type number
Expected result when fuzzed field is required4XX
Expected result when fuzzed field is optional4XX
Expected result when fuzzed value is not matching field pattern4XX
Fuzzing logicIteratively replaces number fields with extreme negative decimal values: -1.7976931348623157E308 for format float, -3.5953862697246314E+308 for format double and -999999999999999999999999999999999999999999.99999999999 * 1.7976931348623157E308 for no format
Conditions when this fuzzer will be skippedWhen field is not of type number
