## 总结
|
|
|
|
该 VBA 自动化测试系统通过**代码编织技术**实现了：
|
|
|
|
1. **非侵入式测试**：在内存中修改代码，不保存到磁盘
|
|
2. **精确行号定位**：通过行号标签和 Source Map 实现源代码映射
|
|
3. **调用链追踪**：通过 CallStack 类追踪完整调用路径
|
|
4. **批量测试支持**：支持单过程和全项目两种测试模式
|
|
5. **详细错误报告**：包含错误位置、源代码、调用链等完整信息
|
|
|
|
系统的核心创新在于将编译器中的**代码编织技术**应用于 VBA 动态测试，通过在运行时注入检测代码来实现传统 IDE 无法提供的调试功能。
