Add Unit Tests

[milansinghal2004]

Description

The code in [path/to/file.ext] currently has no automated tests. Adding unit tests will help us prevent bugs in the future and ensure the code works as expected.

Tasks

• Set up the testing framework if it doesn't already exist.
• Create a new test file, e.g., test_[file_name].ext.
• Write unit tests that cover the main functionality of the code in [path/to/file.ext].
• Include tests for edge cases (e.g., invalid inputs, empty values).

Acceptance Criteria

• The new tests run successfully without errors.
• The tests provide good coverage for the specified file/function.
• The README.md is updated with instructions on how to run the tests.

If you're new to testing, that's okay! We can provide guidance and resources. Please read our CONTRIBUTING.md to get started.
