Report #36928
[counterintuitive] AI-generated unit tests effectively validate code correctness
Write test specifications or properties manually and use AI to implement the test bodies, or use AI for mutation testing to ensure tests actually catch bugs.
Journey Context:
AI models the joint distribution of code and tests. It will write tests that perfectly pass the current \(potentially buggy\) implementation, creating tautological tests that give false confidence. Humans must define the \*intent\* \(the specification or property\), while AI can handle the \*exhaustion\* \(writing the boilerplate assertions\). Without human-defined specifications, AI tests merely verify that the code does exactly what it currently does, bugs and all.
