Fuzz Testing

Maintainer guide for property/fuzz coverage.

Profiles

• PR smoke: HYPOTHESIS_PROFILE=ci_smoke pytest -m "fuzz" -q
• Nightly deep: HYPOTHESIS_PROFILE=nightly_deep pytest -m "fuzz" -q

Deterministic Coverage Gate

$ PYTHON_BIN=.venv/bin/python bash scripts/run_coverage.sh

Notes:

• Coverage gate is 100% for src/honestroles.
• Keep chart/EDA tests deterministic even when optional plotting deps are missing.
• Do not rely on optional extras at runtime to make coverage pass.

Scope

Current fuzz suite targets:

• Runtime pipeline robustness on heterogeneous row shapes
• Plugin manifest loading and callable validation behavior
• CLI argument handling stability

Reproduction

$ pytest path/to/test.py::test_name -q -s
