Agent-driven synthetic monitoring with Amazon Nova Act replaces brittle UI scripts
AWS ML Blog · rss · 2026-09-28
AWS ML Blog walks through building agent-driven synthetic monitoring with Amazon Nova Act and Bedrock AgentCore, with a full sample repo:
- Problem: Traditional Selenium/Playwright tests rely on DOM selectors and break on small UI changes; maintenance often costs more than building new automations.
- Approach: Nova Act reasons from screenshots instead of selectors, replacing 10+ lines of locators with calls like act("Click the checkout button"); early enterprise cases show 90%+ accuracy on browser workflows.
- Architecture: EventBridge Scheduler (5 min to hourly) → AgentCore Runtime (serverless, session isolation) → AgentCore Browser (managed remote browser) → SNS failure alerts.
- Details: Use actget() boolean assertions to explicitly validate outcomes (cart contains items, no error banners); a six-step journey typically takes 2–4 minutes; applies to e-commerce checkout, banking flows, bookings, and SaaS signup paths.
