Shift-Left Testing
A testing methodology in software engineering that moves testing activities from the end of the development process to earlier stages, incorporating quality assurance at the requirements phase. Early defect detection is achieved through CI/CD pipelines, automated testing, and related practices.

Validation checkpoints should be placed at the cheapest stage; the cost order is text validation < image validation < video generation, with unit costs increasing the further along the process.
左移测试的理念源于软件缺陷修复成本随开发阶段呈指数增长的经验法则
本地验证回执在代码进入自动化流水线前提供第一道质量关卡，减少无效提交进入 CI 系统带来的资源浪费和反馈延迟，与「左移测试」理念一致
