fuzzlogfmt

Package fuzzlogfmt implements fuzzing functions compatible with github.com/dvyukov/go-gofuzz to test github.com/go-logfmt/logfmt.

Fuzzing functions

func Fuzz tests that any input accepted by logfmt.Decoder can be written by logfmt.Encoder and that a second round trip of the data produces identical output.

func FuzzVsKR tests that any input accepted by logfmt.Decoder is also accepted by github.com/kr/logfmt.Unmarshal.

Usage

Installing go-fuzz

The installation instructions for go-fuzz are a bit buried in that project's README. For convenience the command is:

go get -u github.com/dvyukov/go-fuzz/go-fuzz github.com/dvyukov/go-fuzz/go-fuzz-build

Building the fuzzing binary:

After cloning this repository and changing dir to its root dir run

go-fuzz-build

That should produce a file name fuzzlogfmt-fuzz.zip.

Fuzzing commands

To fuzz with func Fuzz run the following command.

go-fuzz -bin=fuzzlogfmt-fuzz.zip -func=Fuzz -workdir=_testdata

To fuzz with func FuzzVsKR run the following command.

go-fuzz -bin=fuzzlogfmt-fuzz.zip -func=FuzzVsKR -workdir=_testdata_vskr
