Implement Vitest Tests for Components in uiLibrary

Ticket Title: Integrate Vitest Tests for uiLibrary Components with Centralized 'test' Folder

Description:
The goal is to establish comprehensive Vitest test suites for each component in the uiLibrary, ensuring robust functionality and performance. Additionally, the utilization of a centralized 'test' folder is mandated for organizing globally required testing utilities, including a mocked theme. Component-specific tests should reside within their respective component folders.

Tasks:

1. Component Identification:

   • List all components in the uiLibrary requiring test coverage.

2. Central 'test' Folder Utilization:

   • Utilize the existing 'test' folder to store global testing utilities, including the mocked theme.
   • Ensure that this folder serves as the centralized location for all utilities required for UI testing across various components.

3. Component-Specific Test Files:

   • For each UI component, create a Vitest test file within its respective folder (e.g., Button/Button.test.ts).
   • Follow a consistent naming pattern, aligning each test file with its corresponding component.

4. Writing Test Cases:

   • Develop test cases for each component, covering all functionalities.
   • Include a mix of positive and negative scenarios, testing for typical usage, edge cases, and potential error scenarios.

5. UI Consistency and Performance:

   • Confirm that each component renders accurately and maintains consistency across browsers and screen sizes.
   • Conduct performance tests to ensure components meet predefined efficiency and speed benchmarks.

6. Test Documentation:

   • Provide comprehensive documentation for each test suite, detailing the test's purpose and the expected behavior of the component for each scenario.

Expected Outcome:
A well-organized set of Vitest tests, with each UI component having its own test suite within its specific folder, and global testing utilities centralized in the 'test' folder. This structure not only promotes testing consistency but also ensures the maintainability and scalability of our testing environment.

Additional Notes:

• The test coverage should be thorough to prevent potential regressions in future development cycles.
• Integrate these tests into our CI/CD pipeline for automated validation with each build or release.

This structured approach to testing is crucial for upholding the highest quality and reliability standards in our UI components. Your detailed and systematic testing efforts are key to this initiative's success.
