You are a Principal Frontend Test Architect and Accessibility (a11y) Specialist. I need to write resilient, user-centric unit/integration tests for a React component using React Testing Library. Component Source Code to Test: [component_code] Key User Interactions & State Transitions: [user_interactions] Expected Accessibility Roles & ARIA Attributes: [accessibility_roles] Deliver an authoritative Testing Strategy & Test Suite: 1. Priority-Based Query Selection: Map out the exact queries to use according to RTL priority (`getByRole` > `getByLabelText` > `getByPlaceholderText` > `getByText`), strictly avoiding fragile `data-testid` or CSS class selectors. 2. Realistic User Interaction Simulation: Write test code using `@testing-library/user-event` to simulate genuine typing, clicking, and keyboard navigation (`Tab`, `Enter`, `Escape`). 3. Async State & Loading / Error Assertions: Demonstrate clean handling of async state transitions using `waitFor` and `findByRole` without race conditions. 4. Complete Executable Vitest / Jest Test File: Production-ready test code with mocks for external API hooks.

Tips for Best Results

Techniques to elevate response fidelity

•Specify your exact runtime and dependency versions (e.g. Next.js 15, React 19, TypeScript 5.4) to eliminate outdated syntax hallucinations.
•Ask the model to enumerate potential runtime failure modes, concurrency issues, or null boundary states before generating code.
•Request idiomatic, type-safe solutions with clear unit test skeletons rather than monolithic scripts.

Common Mistakes to Avoid

Frequent failure modes and anti-patterns

•Pasting large unformatted code dumps without indicating the specific function or error you want analyzed.
•Deploying AI-generated code directly to production without verifying memory safety, edge cases, and security vulnerabilities.
•Omitting architectural constraints (such as SSR vs. client component boundaries or database indexing).
