Proposal to Add Unit Tests and CI Workflow Using GitHub Actions

[legendkartik45]

I propose adding unit tests to improve code reliability and establishing a CI workflow using GitHub Actions to run these tests automatically on each pull request and commit. This setup will help maintain code quality and streamline development by catching potential issues early and providing contributors with immediate feedback.

@richardyhz @alanalanlu Do let me know how this sounds, I will probably work on this over the weekend. Thanks.
