[counterintuitive] Relying on AI-generated unit tests to verify implementation correctness

Use AI to generate test scaffolding and mock structures, but manually inject the test oracle \(the expected outcome\) or use property-based testing.

Journey Context:
AI reads the implementation to write the test, resulting in tautological tests that verify the code does exactly what it does, even if it's wrong. Humans write tests against the specification. AI-generated tests pass on buggy code with high coverage, giving a dangerous illusion of correctness that hides logic flaws.
