[BUG] The project currently lacks a testing framework

[udaykiran243]

Describe the bug

The project currently lacks a testing framework. Adding one is crucial for preventing regressions and ensuring component reliability as the project grows.

Steps to reproduce

Since this is a Vite project, setting up **Vitest** is recommended over Jest for better compatibility and speed.

Expected behavior

• Install vitest, jsdom, and @testing-library/react.
• Add a test script to package.json.
• Create a sample test for a simple component (e.g., LoadingSpinner.jsx or Footer.jsx) to verify the setup.
• Document how to run tests in README.md.

Affected component

Frontend (React/Vue)
