Fuzz Tests

Fuzzing Genji with go-fuzz.

Quick Start

1. Install go-fuzz

   go install github.com/dvyukov/go-fuzz/go-fuzz-build github.com/dvyukov/go-fuzz/go-fuzz
   

2. Download the initial corpus

   git clone https://github.com/genjidb/go-fuzz-corpus testdata/fuzz
   

3. Build the test program with necessary instrumentation

   go-fuzz-build -func FuzzParseQuery
   

   This will produce fuzz-fuzz.zip archive.

4. Run the fuzzer.

   go-fuzz -workdir=testdata/fuzz/FuzzParseQuery
   

   The results will be written to testdata/fuzz/FuzzParseQuery. Note that go-fuzz runs forever until manually stopped.

   Example output:

   …
   2020/10/14 12:03:58 workers: 2, corpus: 166 (13s ago), crashers: 2, restarts: 1/9663, execs: 1526845 (16418/sec), cover: 924, uptime: 1m33s
   …
   

   Here, corpus is number of interesting inputs the fuzzer has discovered, and crashers is number of discovered bugs (check out testdata/fuzz/FuzzParseQuery/crashers dir).

See README file from go-fuzz for more information.
