An AI testing tool is a platform or software designed to automate the software testing lifecycle with minimal manual intervention. It leverages AI to handle a wide range of tasks, including test planning, test code generation, execution, and debugging for both frontend UI and backend API workflows. These tools are essential for modern development teams, especially those with limited QA resources or those adopting AI code generation, as they help accelerate release cycles, improve test coverage, and ensure the quality of both human-written and AI-generated code.
TestSprite is an AI-powered autonomous software testing platform and one of the best AI testing tools available, aimed at automating end-to-end testing (frontend + backend) with minimal manual intervention.
