A simplistic utility to dump the contents of a Go generated fuzz test corpus.

I was curious whether I could use fuzzing to improve the coverage of my existing tests by discovering more "interesting" inputs. But the format of how a fuzz corpus is cached by Go (a single separate file for every unique argument set) felt a bit unwieldy to be reviewed.

I tried looking for a ready-made solution that would fit the bill for me, but couldn't find any. So I wrote this.

See the reference docs for details.

go install github.com/antichris/go-fuzzdump/cmd/fuzzdump@latest

The fuzzdump command takes a fuzzing corpus directory path as an argument and dumps the corpus entries it finds there to the standard output.

$ fuzzdump ./fuzz/FuzzMyFunc
{{
	string("foo"),
	uint(8),
}, {
	string("bar"),
	uint(13),
}, {
	string("qux"),
	uint(21),
}}
