A software tester is randomly generating invalid inputs in an attempt to crash the program. Which of the following is a software testing technique used to determine if a software program properly hand

Mutation testing modifies existing source code or test cases to verify that the test suite detects the changes, rather than feeding invalid inputs to the program.

Randomizing is not a formal, recognized software testing methodology and does not describe a structured approach to invalid input generation.

Fuzzing (fuzz testing) specifically targets robustness by generating invalid, unexpected, or random data as inputs and observing whether the program crashes or behaves insecurely. It is widely used in security testing to uncover input validation flaws, buffer overflows, and other vulnerabilities that may not surface during normal testing.

Boundary value testing (bounding) uses inputs at the edges of valid ranges, not arbitrary invalid or malformed data, to test how a program handles limit conditions.
