[counterintuitive] AI can reliably write unit tests for the code it just generated, ensuring correctness

Write the test assertions yourself based on business requirements, and only delegate the test setup and boilerplate to the AI. Never let AI write assertions for its own logic without human specification of the expected outcome.

Journey Context:
Developers think AI writing tests is a safe delegation because tests are 'simple'. This is an illusion. AI writing tests for its own code results in tautological tests \(testing the implementation, not the specification\). If the AI wrote a bug, it will write a test that asserts the buggy behavior is correct. AI misses entire bug classes because it optimizes for code coverage metrics rather than risk coverage. Humans are superior here because they test against intent and edge cases, not just execution paths.
