Configuration

Copy Markdown View Source

ExFuzz reads its configuration from the :ex_fuzz key of your project in mix.exs:

def project do
  [
    app: :my_app,
    ex_fuzz: [
      corpus_dir: "test/fixtures/fuzz",
      cache_dir: "_build/ex_fuzz/corpus",
      crash_dump_dir: "_build/ex_fuzz"
    ]
  ]
end

Options

  • :corpus_dir - directory to store failing inputs as seed corpus. Defaults to "test/fixtures/fuzz".
  • :cache_dir - directory to cache fuzzing progress. Defaults to "_build/ex_fuzz/corpus".
  • :crash_dump_dir - directory to store crash dumps during fuzzing. Defaults to "_build/ex_fuzz".

Paths are relative to your project's root.
