Testing for WebDev Codebase

[manascb1344]

Introduce comprehensive testing to the WebD codebase using the React Testing Library.

• Add unit tests to the codebase to verify the functionality of individual components and ensure they behave as expected.
• Incorporate integration tests to validate the interactions between different components and modules within the application.
• Utilize the React Testing Library to run the tests, providing a user-centric approach to testing React components.
• Ensure that all components have adequate test coverage to prevent regressions and maintain high-quality standards throughout the development process.
