Report #46978

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

Generate tests from specifications or docstrings, not the implementation body. Use AI to generate property-based tests or mutation testing setups rather than example-based implementation-mirroring tests.

Journey Context:
AI writes tests that are highly coupled to the implementation it just generated, leading to tautological tests that pass even if the logic is broken. Humans write tests based on the specification. AI tests the 'how', humans test the 'what'. Mirroring implementation in tests provides a false sense of security.
