Request: Please add a testing helper for the project #14

Hello,

Thank you for your hard work on this project!

I would like to suggest adding a testing helper to the repository. A testing helper could make it easier for contributors and users to write and maintain tests, and help ensure consistency across the codebase.

I also noticed that there have been no commits to this repository from July 20, 2025 to January 18, 2026, based on the commit history I checked. May I kindly ask if the project is still actively maintained?

If you have any specific requirements or preferences for how the testing helper should be implemented, please let me know. I would be happy to assist or discuss further if needed.

Thank you for considering this suggestion!
