Epsilon builds intent-driven UI testing service on Amazon Nova Act

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, according to an AWS Machine Learning Blog post published October 29, 2026.

The service runs plain-English test steps in ephemeral AWS-managed browser sessions, layered on top of Epsilon's existing Playwright regression suite.

According to the post, teams access the service through the platform's standard API and do not manage browser infrastructure themselves. Epsilon's platform team says it can deliver resilient, intent-driven testing as a service, and onboarded teams consume it the same way they consume other platform agents. The source is a first-party AWS post, and no independent results or performance figures are reported.
