A green AI test suite can be a group project between the code and its mocks

A green AI test suite can be a collaborative project between the code and its mocks. While AI can generate most of the test suite, at least one test should originate externally, such as a captured API payload or an old migration fixture. This external input prevents the code from grading its own homework with an answer key it also created, ensuring a more robust and independent evaluation of the feature written by the agent.
