Implement Jest Tests for Core Functionality

[AyushDharDubey]

Description

Currently, the project lacks unit tests and integration tests for core functionality such as utility functions, components, and API data handling. Implementing tests using Jest will ensure the project's stability and make future feature development safer.

---

Tasks

• Set up any robust testing framework (not confined to jest).
• Write Unit Tests for utility functions to confirm that components like TicketCard render the right data under different conditions
• Make sure to that utility functions like getTickets handle failure scenarios gracefully.
• Document the testing setup

---

Acceptance Criteria

• A testing setup exists and tests can be executed locally.
• Critical functions and components are verified under both success and failure cases.
• Documentation is updated so others can run or write their own tests.

Meanwhile, while writting tests if you figure out any bug or breakage somewhere, feel free to create an issue.
