Enable Go fuzzing with the -asan flag and run tests using -test.fuzz to automatically detect memory errors and logic bugs.
Enable fuzzing in Go by adding the -asan flag to your build command to instrument code for memory error detection. Run your fuzz test with the -test.fuzz flag pointing to your Fuzz function name.
go test -asan -c -o myapp.test ./myapp
go test -fuzz=FuzzMyFunc -fuzztime=10s ./myapp
Fuzzing is a way to automatically find bugs by feeding your code random or mutated inputs to see if it crashes. It matters because it catches memory errors and logic flaws that manual testing often misses. Think of it as a tireless robot tester that tries to break your software by throwing everything at it.
