Microsoft releases ASSERT for AI behavior testing

Microsoft released ASSERT, an open-source framework that converts natural-language descriptions of AI behavior into structured, scored tests. ASSERT transforms high-level goals and policies into detailed test cases, runs them against AI systems, and scores results with failure paths including intermediate actions and tool calls. The tool enables developers to evaluate application-specific AI behavior using plain language inputs. It supports regression testing and helps detect deviations from intended behavior during execution. ASSERT is designed for developers building AI systems that require precise, real-world behavior validation.
