CAST: Coordinated Agent Swarm Testing as a Substitute for Human Beta Testing in Web Application Development

Julie Golston · Scaffold Studios

This paper introduces CAST, a methodology that deploys 100 Claude AI agents organized into five specialized squads to perform structured static analysis of web application source code. Applied to a 12,500-line React/TypeScript application, CAST identified 687 unique findings across security, logic, robustness, performance, and data integrity categories at a total cost of $7.97 in 63 minutes — compared to $2,000–$20,000 for equivalent human beta testing.
