Unit Test Generation for Codebase

Objective: Generate unit tests for the provided codebase to ensure code correctness and prevent regressions.

Instructions:

1. Analyze the attached code and identify its core functions and methods.
2. Generate unit tests that cover a wide range of input values and expected outputs for each function/method.
3. Follow best practices for unit testing, including:
   • Test one function/method per test case.
   • Use descriptive test names.
   • Assert expected outcomes clearly.
   • Keep tests independent and isolated.
4. Prioritize test coverage for critical functionalities and edge cases.

Expected Output: A comprehensive suite of unit tests that can be used to verify the correctness of the codebase and prevent regressions during future development.
