Migrate Testing Framework from Jest to Vitest

[GauravSaini01]

Description
We propose migrating from Jest to Vitest as our testing framework. Vitest offers faster test execution and enhanced TypeScript support, making it an ideal choice for our project. This migration will involve updating our test files to be compatible with Vitest and replacing Jest-specific methods with Vitest equivalents.

Why This Change is Necessary

• Improved Speed: Vitest is designed to be faster than Jest, providing quicker test runs.
• TypeScript Support: Vitest offers native TypeScript support, which can improve our development experience.

Do we really need to migrate the testing framework for Node.js scripts ?

It doesn't currently feel like a need of the hour to migrate from Jest to vitest. We are currently using Jest for pure Node scripts. No React Testing Library of JSDOM.
