Question

You asked an AI agent to 'add tests to get the `PricingEngine` module to 90% coverage.' It delivered: coverage jumped to 91%, all green. The PR looks like solid test work. Before you trust that this module is now well-tested, how do you judge whether these tests are meaningful or just coverage theater?

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.
