A walkthrough of testing MCP (Model Context Protocol) servers using the DeepEval library. Demonstrates an e-commerce application with an MCP server accessed via Claude Desktop, then shows how to write multi-turn conversational test cases using DeepEval's MCP metrics and pytest. Tests run locally with a Qwen 3.5B model acting as both the application LLM and the LLM-as-judge evaluator, validating tool invocations like product search, add-to-cart, and order creation without manual verification.
