Report #57109
[counterintuitive] AI-generated tests prove AI-generated code is correct
Write test oracles independently from implementation. Use TDD: specify expected behavior before generating code. Use property-based testing with human-defined invariants. Never let the same AI session generate both the implementation and its validation tests.
Journey Context:
When AI generates both code and tests, the tests encode the same misconceptions as the code. Tests pass, creating dangerous false confidence. This is the self-validation anti-pattern. SWE-bench evaluations show AI agents frequently produce solutions that pass existing tests but are semantically incorrect. When AI writes its own tests, the problem compounds: tests are tailored to the wrong implementation, so they pass trivially. The human equivalent is a student grading their own exam — the checks lack adversarial pressure. The fix is separation of concerns: one agent \(or human\) specifies what correct means, another implements it.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
