AI agents require regression gating, not unit tests, for reliable output

Traditional unit testing methods, which rely on exact output matching, are insufficient for AI agents due to their non-deterministic nature. Instead of asserting precise string equality, developers should focus on 'regression gating.' This involves verifying essential facts that must be present in the output (must-include) and ensuring forbidden strings or patterns do not appear (must-exclude). This approach allows for deterministic testing of critical invariants, even when the agent's phrasing or ordering of information varies. AI

IMPACT This approach could improve the reliability and safety of AI agents by providing a more robust testing framework than traditional unit tests.
