用 Claude Code 打造 Agent 数字孪生，零代码完成测试
用 Claude Code 给 Agent 造个数字孪生，所有工具都 mock 掉，测试完全不碰生产环境。比手动写测试用例省事，还能让模型自己找问题、给修复方案。做 Agent 开发的朋友可以照着试一遍。
开发者 Santiago 展示了一种不写代码测试 Agent 的方法：用 Claude Code 为 Agent 创建数字孪生（digital twin），在模拟环境中验证行为。
该方法的核心是把 Agent 触及的每一个工具都做成 mock，把每一个要执行的函数都放进模拟里跑，从而避免测试流量打进生产环境。据其描述，这套流程能发现连开发者自己都没预料到的 Agent 问题，并给出对应的修复建议。
I built an agent and tested it without writing a single line of code.
Here is how to create a digital twin of your agent, mock every tool it touches, and simulate every function it runs without affecting production.
I'm using Claude Code here.
Probably the closest thing to magic you'll see this month.
This will test and discover problems with your agent that you didn't even know were possible.
It will then tell you how to fix everything it finds.
