Tiny "automatic" fuzzer for chromium using puppeteer. [WIP]

Domato generates fuzz files.
Puppeteer running in headless mode for testing.
Make sure that you've downloaded Chromium with ASAN in asan-mac-release folder.

1. Generate fuzz files with domato.
2. Serve these files using serve.
3. Run puppeteer against every generated file.

  git clone https://github.com/Metnew/molybden.git && cd molybden
  npm i

Make sure you have python and it exists in $PATH!

# Generate 100 fuzz files in ./dist folder
npm run generate
# Which is equal to:
# python ./domato/generator.py  --output_dir ./dist --no_of_files 100

npm run generate accepts env vars:

• DOMATO_DIR - output_dir for domato
• DOMATO_NUM_FILES - number of files to generate

# Generate 1337 fuzz files in ./hello/world folder
DOMATO_DIR=./hello/world DOMATO_NUM_FILES=1337 npm run generate
# Which is equal to:
# python ./domato/generator.py  --output_dir ./hello/world --no_of_files 1337

IMPORTANT: domato can't generate folders for your files. You have to create empty folder for fuzz files (e.g. ./dist) by yourself. Else you'll get:

Writing a sample to ./dist/fuzz-0.html
Error writing to output
Writing a sample to ./dist/fuzz-1.html
Error writing to output

Run mkdir ./dist before npm run generate!

# Start puppeteer using files from DOMATO_DIR.
npm run start
# Which is equal to node `./src`

npm run start accepts env vars:

• DOMATO_DIR - folder with generated fuzz files
• PORT - free port for serve
