Implement Unit Tests for Enhanced Code Quality and Reliability

[labala-sravani]

Description:
The project currently doesn't have unit tests, which makes it harder to ensure the code is working as expected and can lead to bugs going unnoticed. Adding unit tests will help catch issues early, improve code quality, and make it safer to make changes in the future.

Benefits of Unit Tests:

• Catch Bugs Early: Unit tests help identify bugs before they make it to production.
• Easier Refactoring: When you want to improve or change the code, unit tests will ensure existing functionality still works.
• Documentation: Unit tests serve as living documentation that show how different parts of the app should behave.
• Better CI/CD Integration: Unit tests can be automatically run during builds to make sure everything is still working after code changes.

Why It’s Important:
Adding unit tests will take some time, but it will make the codebase more reliable, easier to maintain, and safer to change in the long run.
