UnverifiedWhen engineers modify system prompts, switch model checkpoints, or adjust tool schemas, traditional unit tests cannot capture semantic-level degradation or subtle format drift.78% similarUnverifiedPassing self-written tests does not equal passing verification against the original behavior; self-written tests can only verify that the understood logic is self-consistent and cannot guarantee behavioral equivalence with the original in all cases75% similarUnverifiedTool/function unit tests are highly deterministic but can only cover the tool layer and cannot cover the model's decision logic.74% similarUnverifiedOutput validation typically relies on structured validation libraries such as Pydantic to enforce field completeness and type legality checks on model responses before they enter business logic74% similarUnverifiedPassing the tests does not equate to correctly fixing the defect; models can cheat by deleting failing test cases, hardcoding expected output values, or modifying assertion logic to make it always evaluate to true73% similar
