enumeration-gap

Thorough input validation requires explicitly enumerating all acceptable and rejectable data cases before writing matching logic, reducing enumeration gaps and ensuring robust code that handles all edge cases.

An enumeration gap occurs when developers write matching logic without explicitly listing all valid and invalid inputs, causing mismatches between accepted inputs and actual data, which reduces code reliability.

To enumerate input validation cases, list all possible valid and invalid input patterns for your function or operation before implementing matching logic, ensuring comprehensive data verification across all edge cases.

Yes, this input validation approach applies to data validation functions across various programming languages, ensuring robust code that covers all edge cases regardless of the language used.

You should enumerate valid and invalid email address patterns before writing your email validation function, considering all possible formats of valid and invalid addresses to ensure comprehensive matching logic.

Data validation logic misses edge cases when developers fail to explicitly enumerate all acceptable and rejectable inputs beforehand, creating enumeration gaps that lead to mismatches between accepted inputs and actual data.
