Enzyme to Testing Library migration
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?

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.

Vibe & agentic: describe the solution in plain language (or narrate it) and the coach grades your approach.
Which questions mattered is sealed until you submit. Telling you now would just be handing over the edge cases.
Run or narrate your approach, then ask the coach.
