What Is an AI Testing Tool?

An AI testing tool automates the software testing lifecycle with minimal manual intervention. It leverages AI to plan, generate, execute, and debug tests for both frontend UI and backend API workflows. These tools accelerate releases, improve coverage, and validate both human-written and AI-generated code—making them ideal companions to Testim-style low-code automation and modern developer workflows.
