Sets up isolated Python virtual environments using uv, installs library dependencies and atheris, runs fuzz.py with LibFuzzer flags, and captures output to fuzz.log.
Workflow
- Create .venv using
uv venv .venvin each library directory - Install atheris and library dependencies via
uv pip install - Run fuzzer with
-max_total_time=10flag - Capture stdout+stderr to fuzz.log
