Question

You asked an AI agent to write a test for `transferFunds(from, to, amount)` in your payments service. It produced a test that mocks the database, calls `transferFunds`, and asserts the function returned `{ success: true }`. The test passes. Judge whether this is a meaningful test of a money-moving operation, and what you'd require instead.

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.
