How would you unit test a React title component?
This tests React Testing Library's user-centric approach and Jest basics. A strong answer renders the component, queries the h1 by role or text, and asserts it is in the document. A red flag is using Enzyme shallow rendering or testing internal state.
This question tests whether you understand React Testing Library's guiding principle: tests should resemble how users interact with software, not inspect implementation details. A strong answer covers four steps: import render and screen, render component with a known title, query heading by getByRole or getByText, and assert presence with toBeInTheDocument. Mentioning that querying by role improves accessibility is a plus. A red flag is Enzyme shallow rendering, testing component instances, or defaulting to data-testid when text is available.
