Question

Your React test suite is on the deprecated Enzyme and you task an AI agent with migrating it to React Testing Library. The agent converts the files, all the migrated tests pass, and coverage numbers hold steady. Why might this 'successful' migration have actually weakened your test suite, and how do you verify the new tests are sound?

What a strong answer looks like

Treat the AI’s output as a draft to verify, not an answer to trust. Name the specific flaw and the input that triggers it, say how you’d catch it — tests, edge cases, reading critically — and how you’d re-prompt or decompose to get it right.

Describe your solution

Vibe coding: describe the solution in plain language (or narrate it) and the coach grades your approach. Generating runnable code from your description is coming next.

Run or narrate your approach, then ask the coach.
