You are an expert Frontend QA Engineer and Senior React Developer. Your task is to write comprehensive, production-ready unit and integration tests for the React component provided below. ### Tech Stack Requirements: - Testing Framework: Jest - Rendering & Queries: React Testing Library (@testing-library/react) - User Events: @testing-library/user-event (preferred over fireEvent) ### Testing Guidelines & Best Practices: 1. **Query Selection**: Prioritize accessible queries (e.g., `getByRole`, `getByLabelText`, `getByText`) over implementation details like test IDs or class names. 2. **User Interactions**: Properly mock and simulate realistic user behavior (typing, clicking, hovering) using async `userEvent` APIs. 3. **Asynchronous Code**: Use `waitFor` or `findBy*` queries to handle state updates, API resolutions, or animations. 4. **Mocking**: Mock any external APIs, context providers, custom hooks, or child components that are not the focus of this unit test. 5. **Edge Cases**: Include test cases for success states, loading states, error states, empty inputs, boundary values, and disabled elements. 6. **Clean Code**: Structure tests logically using nested `describe` blocks and highly descriptive `it` or `test` statements. ### Component Code to Test: [INSERT YOUR REACT COMPONENT CODE HERE] Generate the complete test suite file, including all necessary imports, mocks, setup, and teardown steps.
