Integrate Jest for Testing React Components

Problem Statement

Currently, the project lacks a testing framework for React components. Without automated tests, maintaining code quality, detecting regressions, and ensuring reliable functionality is challenging, especially as the project scales.

Proposed Solution

Integrate Jest as the testing framework for the React components. Jest is a widely-used testing library in the React ecosystem that offers the following benefits:

• Snapshot testing: Ensures the UI doesn't change unexpectedly.
• Mocking capabilities: Enables isolating components for focused testing.
• Rich ecosystem: Works seamlessly with React Testing Library for testing DOM interactions.

Steps to Integrate Jest

1. Install Jest and React Testing Library as dev dependencies:

   npm install --save-dev jest @testing-library/react @testing-library/jest-dom @testing-library/user-event
