Improve Unit Test Coverage and Robustness (Especially for Logging) #11
Description
We need to enhance our unit test suite to make it more:
- Comprehensive – especially covering the logging mechanism,
- Modular – easier to maintain and extend,
- Robust – resistant to unintended bypasses.
This is motivated by PR #10, where certain changes were able to bypass existing tests undetected. To prevent regressions and increase confidence in our codebase, we should refactor and strengthen the test suite to be more "foolproof".
Tasks:
- Audit current unit tests for gaps (especially around logging).
- Refactor tests into logical, modular components.
- Add explicit test cases for logging behavior under various conditions.
- Ensure decorator or structural changes cannot silently evade test coverage.
