Question

A test was failing after a feature change. You asked an agent to 'make the test pass' and it did — by loosening the assertion. Here's the before/after it produced for a Python test. Is the suite still protecting you? How should you have steered this differently?

python

1# before2assert response.status_code == 2003assert response.json()["total"] == 424 5# after (agent's fix)6assert response.status_code in (200, 201, 202)7assert response.json().get("total") is not None

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.
