Stubs for input validation; test harness; example test cases.
Moar stubs.
Range validation for integers and numbers; integer input validation.
Test cases for non-integer numeric input.
More input validation; more test cases. We now handle length restrictions on integer/number/string and range restrictions on integer/number.
Allow "length" property on "number"-typed fields; add "integer" to the numeric-range type list for clarity.
