What does fuzz testing primarily aim to accomplish?

Fuzz testing primarily aims to stress the software to find unnoticed flaws by inputting random or unexpected data into the application to see how it handles such inputs. The focus is on discovering vulnerabilities, crashes, and memory leaks that may not be evident during standard testing procedures. By bombarding the system with unexpected data, fuzz testing aims to provoke responses that reveal weaknesses in the application's code and logic, which could potentially be exploited by malicious users.

The approach is particularly effective for identifying security vulnerabilities that are often missed by conventional testing methods, as it simulates real-world attack scenarios where inputs may be unpredictable. This method of testing helps ensure the robustness and reliability of the software by exposing points of failure under extreme conditions.
