This section is dedicated to AI-powered testing with Step. It covers the technologies, workflows, and capabilities that enable autonomous software testing across functional testing, load testing, and monitoring. Whether you are exploring AI-assisted test development through the Step MCP Server, leveraging Reusable Testing Skills, or adopting the Step Testing Agent, this documentation explains how Step integrates large language models (LLMs) into existing testing and CI/CD workflows. The goal is to help teams accelerate automation creation, reduce maintenance effort through self-healing capabilities, and deliver reliable, reproducible testing outcomes at scale.
