RealDevWorld – An AI-Powered Automated Testing Tool Launched by MetaGPT

What is RealDevWorld？

RealDevWorld is a next-generation automated testing tool developed by the MetaGPT team. Built on a multi-agent framework, it simulates the workflow of a real development team, automating the entire process from requirement analysis and test case generation to code debugging and final deployment. Users only need to describe their requirements in natural language, and RealDevWorld will automatically generate test cases, lowering the technical barrier. It features self-healing test scripts that can automatically repair scripts broken by UI updates, reducing maintenance costs. RealDevWorld supports testing across multiple platforms—including Web, mobile, API, and desktop applications—covering the full-stack workflow. It seamlessly integrates with mainstream CI/CD tools such as Jenkins and GitHub Actions, enabling efficient execution of automated testing within development pipelines. With its real-time feedback and optimization mechanism, it iteratively improves based on test results to ensure test cases remain highly aligned with actual requirements. In the RealDevBench benchmark test, RealDevWorld achieved outstanding performance, with 92% accuracy and higher evaluation consistency than cutting-edge models like Claude.
