New Microsoft tool lets devs spin up AI behavior tests using text descriptions

Microsoft released ASSERT, an open-source framework that turns plain-language goals, policies, and constraints into structured tests for AI systems.

The framework uses AI to generate scenarios, run them against a target system, and score the results, including intermediate actions and tool calls.

Microsoft says ASSERT is designed for development-time evaluation, post-deployment checks, and ongoing monitoring of AI behavior.

The tool aims to help developers verify product-specific rules for safety, compliance, and reliable long-term performance.
