Report #81489

[counterintuitive] Does AI-generated unit testing provide the same safety net as human-written tests?

Never trust AI test oracles. Use AI to generate test inputs and boilerplate, but manually assert expected outcomes based on the specification, not the implementation.

Journey Context:
Developers assume high code coverage from AI tests means high confidence. AI reads the implementation and generates tests that simply re-assert the implementation's logic \(tautological tests\). If the implementation has a bug, the AI test encodes the bug. Humans write tests against the mental specification; AI writes tests against the code text. This leads to 100% coverage with 0% bug detection for logic flaws, creating a false sense of security.
