Which concept describes changing existing input values?

Explanation:
Mutating input values means taking existing inputs and altering them to create new test cases. This is exactly what mutation testing and fuzzing do: start with valid data and apply small changes to see if the system detects the differences, testing input validation, error handling, and security controls. It's distinct from generation-based fuzzing, which builds inputs from scratch, and from static analysis (which doesn’t run the program) or dynamic analysis (which tests a running application without necessarily mutating inputs). So mutating input values best describes the concept.
