## Summary

Epsilon, a data and marketing-services company in Publicis Groupe, built a managed UI testing service on Amazon Nova Act and Amazon Bedrock AgentCore Browser Tool for its product teams. The service runs plain-English test steps in ephemeral AWS-managed browser sessions, layered on top of the existing Playwright regression suite. The post says teams get the service through the platform's standard API without managing browser infrastructure themselves.
