52/111 Chaos Engineering @ Netflix 這些是需要整合測試的故障模式示例，因為它們涉及服務之間的互動。在某 些情況下，可能只能在 Production 進行完全整合測試。在 Netflix ，根本不 可能完全重現整個架構並運行端到端測試。 當可以在 Testing 環境中重現整個系統時，我們仍然相信需要在 Production 運行實驗，因為在 Testing 環境中永遠不可能完全重現系統的所有方面。總 是存在差異，例如合併客戶端與真實客戶端相比的行為方式或 DNS 配置問 題。 Credit : Chaos Engineering IEEE Software (2016-05-05).pdf Testing in Production
