Module lint 

The Python mocking mechanism and style lints behind integration lint, plus the Python arm of unit lint. Each test file is parsed with rustpython_parser and walked with a Visitor; the rules themselves are documented under docs/reference/checks/.

Re-exports

pub use crate::violation::Violation;

Functions

find_suite_violations

Every lint violation in package_root’s suite tiers, sorted by (file, line). tests/integration/ and tests/e2e/ both run first-party code for real; a *_test.py under tests/ outside them is unknown-tier rather than silently unscanned.

find_unit_isolation_violations

Every unmocked-collaborator violation under root — a collaborator a *_test.py imports without mocking it — sorted by (file, line). First-party is the dist’s own package ([first_party_package]); a tree that declares none reports nothing.

find_violations

Every lint violation in the Python test files under root, sorted by (file, line). A Python test file is *_test.py or conftest.py, where fixtures live; a legacy test_*.py is ordinary source. A file that cannot be read or parsed is an error.
