Implement Comprehensive Unit Tests

Description

While there are some tests in the codebase, increasing test coverage would improve the overall reliability of the project. Comprehensive unit tests help catch bugs early, facilitate refactoring, and serve as documentation for the expected behavior of the code.

Objectives

1. Increase overall test coverage to at least 80%.
2. Ensure all critical paths and edge cases are tested.
3. Implement unit tests for all public methods and functions.
4. Add integration tests for key features.

Tasks

• Identify areas of the codebase with low or no test coverage.
• Write unit tests for untested functions and methods.
• Implement edge case tests for existing functionality.
• Set up a code coverage tool (e.g., Jest with Istanbul) to track progress.
• Update CI/CD pipeline to run tests and report coverage.

Best Practices

• Use descriptive test names that explain the expected behavior.
• Follow the Arrange-Act-Assert (AAA) pattern in test structure.
• Mock external dependencies to isolate the unit being tested.
• Aim for fast-running tests to encourage frequent execution.
