AgentCheck – Pytest for AI Agents
AgentCheck is a new tool designed for behavioral regression testing of AI agents using a pytest-style framework. It allows developers to test agent behavior rather than exact text outputs, ensuring that agents function as intended. The tool is compatible with Python versions 3.10 and above and offers various optional framework extras for enhanced functionality.
- ▪AgentCheck is released under the MIT license and is currently in alpha development status.
- ▪The tool checks observable agent behavior, including tool usage and execution order.
- ▪Users can run tests, save baselines, and generate HTML reports of test results.
