_⚠️ Potential issue_ | _🟠 Major_

**Add required type hints and Google-style docstrings to public test methods.**

All public test methods here should include parameter/return type hints and Google-style docstrings with Args, Returns, Cost, and Example sections.

As per coding guidelines: “All public methods in generator classes and test files must include type hints for parameters and return values”, “All public methods should include docstrings with Args, Returns, Cost information, and Example sections”, and “Write docstrings for every function using Google style format”.
