This tool modularizes test files after code reuse, creating parameterized and well-organized test functions. It's ideal for improving test organization and structure, creating parameterized test functions that can handle multiple test cases, and enhancing overall test maintainability and readability.

You provide the path to a test file that should be modularized. This tool is typically run after code reuse has been completed to further optimize the test structure. The tool analyzes the test file to identify modularization opportunities, extracts common patterns that can be parameterized, creates reusable functions with clear parameters, and refactors the test file into a more maintainable structure.

The LLM understands testing best practices and applies them to restructure your tests. It creates fixtures, helper functions, and parameterized tests where appropriate, while maintaining test clarity and ensuring all test cases remain properly covered.
