Testing GenUI & Semantic Edge Caching — AI Part 6
Answer-First Summary: Testing non-deterministic Generative UI components and optimizing their global delivery requires combining Visual Regression E2E Testing (via Playwright mock harnesses) with Semantic Edge Caching (via Cloudflare Workers or Vercel Edge Functions). By mocking LLM tool responses during CI/CD test runs and implementing vector similarity caching at the CDN edge, teams achieve 100% deterministic test coverage while reducing AI component latency from 2,500ms down to less than 45ms for cached intent patterns. ...
