python-module-to-package-refactor

What problem does it solve?

Splitting a large Python module into a package often breaks unit tests because unittest.mock.patch targets still refer to the old flat module path. This skill provides clear rules to update patch targets so tests mock the correct lookup path at runtime, preserving test reliability during refactors.

Core Features & Use Cases

• Update patch targets to reflect the actual lookup path after refactoring the module into a package.
• Provide a bottom-up migration checklist for creating the package structure with init.py re-exports.
• Ensure test compatibility by validating patch paths across multiple modules and test suites.

Quick Start

Split the module into a package and update all patch targets to reflect where names are looked up at runtime.
