## 测试环境
- 基础镜像：python:3.11-slim
- Python 版本：3.11
- 测试对象：cncsmonster/dotfiles

## 测试步骤
1. ✅ Dry-run 测试（验证配置解析）
2. ✅ 实际部署（验证 symlink 创建）
3. ✅ 结果验证（检查 symlinks 正确性）
4. ✅ Undeploy 测试（验证清理功能）

## 验证项目
- [cncsmonster/dotfiles](https://github.com/cncsmonster/dotfiles)

## 测试配置
- 主配置：xdotter.toml (3 个 dependencies)
- 子配置：shells/, langs/, nvims/
