Create fuzz testing harnesses with Copilot for input validation

“

Fuzz testing discovers vulnerabilities through millions of malformed inputs, testing what happens when users send garbage, attackers send exploits, and the universe sends edge cases your spec's never considered. Copilot generates the harness, your understanding of attack surface guides what to fuzz. Copilot generates complete fuzzing setups for industry standard frameworks, AFL++ for file format and protocol fuzzing, LibFuzzer for in-process C or C++ fuzzing. The generated code includes harness implementation, build configuration with sanitizers, initial seed corpus, and execution scripts. You provide the target functions and context. Copilot provides the framework integration. You need to prompt with specifics. For example, generate libFuzzerHarness for parseJSONRequest function with addressSanitizer, targeting inputs up to 10MB with 60 second timeout. Not all code benefits equally from fuzzing. API endpoints accepting user input are prime targets. File parsers handling untrusted…
