langgraph-testing

What problem does it solve?

This Skill streamlines the testing of LangGraph agents and graphs, ensuring the reliability and correctness of complex state machine logic.

Core Features & Use Cases

• Multi-level Testing: Supports testing individual nodes, partial graph flows, and end-to-end execution.
• State Isolation: Employs the Graph Factory pattern and MemorySaver for isolated test environments.
• Use Case: When developing a multi-turn conversational agent with LangGraph, use this Skill to write comprehensive tests that verify each step of the conversation, from initial user input to final agent response, including tool usage and state transitions.

Quick Start

Use the langgraph-testing skill to write pytest tests for your LangGraph graph by creating a fresh graph instance and checkpointer for each test.
