Is your feature request related to a problem? Please describe

The file is currently tested using Jest. As part of our migration to Vitest, we need to refactor this file's test cases to align with Vitest's syntax and features.

Acceptance Criteria

• Replace Jest-specific functions and mocks with Vitest equivalents.
• Rename the test file from having a .test.* suffix to a .spec.* suffix.
• Ensure all tests in the file pass after migration using npm run test:vitest.
• Maintain the test coverage for the file as 100% after migration.
• Upload a video or photo showing that this specific file's coverage is 100% in the PR description.

Additional Context

• Refer to the merged PR for the base Vitest configuration:
