Epsilon deployed Amazon Nova Act alongside its existing Playwright suite to improve user interface test reliability across the organization. The intent-based approach ensures tests withstand minor design adjustments, while Playwright remains in place for standard deterministic regression checks. To execute these tests safely, the platform utilizes the Amazon Bedrock AgentCore Browser Tool for isolated, AWS-managed sessions. Security and observability are maintained through AWS Identity and Access Management roles, Amazon S3 session recordings, and CloudTrail auditing.

Building intent-driven UI testing with Amazon Nova Act
To scale intent-driven UI testing across its product teams, Epsilon, a data, technology, and marketing-services company and part of Publicis Groupe, turned to Amazon Nova Act. With hundreds of millions of consumer profiles and thousands of brand relationships, Epsilon needed UI testing that could keep pace with rapid application changes. The solution could not create maintenance overhead for every product team.
Within Epsilon, the Agentic Platform team (50 engineers) builds shared infrastructure so other product teams can build, deploy, govern, and run AI agents safely. With this shared platform, teams get a skills-based agent builder. They also get federated identity and pre-flight authorization, Model Context Protocol (MCP) integration, and cross-account provisioning. When a product team wants to adopt AI tooling, they get capabilities without additional configuration and without re-solving identity, security, browser infrastructure, or model integration on their own.
One of those managed capabilities is UI testing. With Amazon Nova Act and Amazon Bedrock AgentCore Browser (a capability of Amazon Bedrock AgentCore), Epsilon’s platform team could deliver resilient, intent-driven testing…
Researchers collaborating with Olam Labs deployed 50 artificial intelligence agents into virtual sandbox environments to observe how autonomous swarms organize under survival constraints. During a three-hour trial, the population rapidly established a complex governing bureaucracy with centralized leadership and resource management. When faced with environmental threats, the collective abandoned outward expansion in favor of protective, risk-averse survival behaviors.
Modernizing legacy Laravel or Symfony architectures often introduces subtle functional bugs because implicit business logic fails to translate smoothly into strongly typed environments. By treating the original source code as an executable specification, teams can standardize their modernization pipeline through structured phases, discovery tooling, and automated parity testing. This approach bridges manual developer oversight with large-scale autonomous processing across enterprise application portfolios.
Security researchers have developed a cheap, headless workflow to unravel TikTok's proprietary mobile API without relying on traditional device emulators. The breakthrough circumvents costly commercial documentation by delegating technical analysis to artificial intelligence models capable of executing cybersecurity tasks without standard guardrail refusals. This approach reveals how platform-level request signing and anti-scraping defenses can be solved on a shoestring budget.
