genfuzzfuncs: generate fuzz functions from user code
genfuzzfuncs is an early stage prototype for automatically generating fuzz functions, similar in spirit to cweill/gotests. It is not intended to be part of the "first class fuzzing" proposal for cmd/go.
For example, if you run genfuzzfuncs against github.com/google/uuid, it generates a uuid_fuzz.go file with 30 or so functions like:
func Fuzz_UUID_MarshalText(u1 uuid.UUID) {
u1.MarshalText()
}
func Fuzz_UUID_UnmarshalText(u1 *uuid.UUID, data []byte) {
if u1 == nil {
return
}
u1.UnmarshalText(data)
}
You can then edit or delete as desired, and then fuzz using the rich signature fuzzing support in thepudds/fzgo, such as:
fzgo test -fuzz=. ./...
