Report #88887
[counterintuitive] AI-generated unit tests provide high confidence in code correctness
Write property-based tests or specification-based tests manually; use AI only to generate boilerplate test cases or increase branch coverage for pure functions.
Journey Context:
LLMs generate tests by heavily attending to the implementation code, leading to tautological tests \(testing that the code does what it does, not what it should do\). This inflates line/branch coverage metrics without increasing fault detection. Humans intuitively trust high coverage, but AI-generated coverage is systematically decoupled from actual regression protection, creating a false sense of security.
