### Test Structure
- Name test files with `.test.ts` or `.test.tsx`.
- Place test files in nearby `__tests__` folders.
- Use descriptive `describe` and `it` blocks.

### Effective Mocking
- Mock external dependencies to isolate tests.
- Use `jest.mock()` for module-level mocks.
- Use `jest.spyOn()` for globals such as `window.open`.
- Reset or restore mocks between tests.

### React Component Testing
- Use React Testing Library.
- Query by accessibility roles, labels, and text.
- Use `userEvent` over low-level events.

### Library Testing
- Cover happy path, edge cases, and error cases.
- Prefer stable assertions over timestamps or locale-sensitive full strings.

### Project Notes
- This repository uses Jest, not Vitest, for the primary automated test flow.
- Run `npm run test -- --runInBand` for verification.
