DevicePlugin 阶段二 Task 4 已完成!✅
完成内容:
1. 更新 MockBackend 支持 Cursor 能力和 SetCursorVisible 命令
2. 新增 4 个测试用例:
- test_mock_backend_set_cursor_visible
- test_mock_backend_cursor_capability
- test_device_command_cursor_serialization
- test_device_capability_cursor
3. 修复 test_mock_backend_capabilities从 2 个能力更新为 3 个)
验收结果:
- ✅ cargo check --workspace --all-targets 零 warning
- ✅ cargo test --workspace 全部通过77/77
- ✅ 新增 4 个测试,验证 ScreenPlugin ↔ DevicePlugin 协作
- ✅ MockBackend 正确声明 Cursor 能力并处理 SetCursorVisible 命令
- ✅ 序列化测试确保 SetCursorVisible 和 DeviceCapability::Cursor 可安全通过 JSON 边界
经验总结:
- MockBackend 是测试 DevicePlugin 的关键,无需真实硬件即可验证命令处理逻辑
- 更新 MockBackend 时需要同步更新相关的能力测试,避免断言失败
- ScreenPlugin 通过 DeviceCommand 消息与 DevicePlugin 协作,实现了松耦合的架构
已更新 souls/li-siqi.md 记录本次任务经验。
Task 4 完成,等待 Task 5文档更新与迁移总结开始。

- SDK 与主库的类型同步需要保持完全一致的派生宏和字段定义
- 添加新的 Message 变体后,需要检查所有现有插件的 match 表达式
- Rust 的穷尽性检查是很好的安全网,确保不会遗漏新增的消息类型
## 个人经验 (2026-03-13 DevicePlugin 阶段二 Task 4)
- 完成 DevicePlugin 阶段二 Task 4集成测试验证 ScreenPlugin ↔ DevicePlugin 协作
- 更新 MockBackend 以支持光标控制:
- capabilities() 添加 DeviceCapability::Cursor
- handle_command 添加 SetCursorVisible(_) => Ok(DeviceResponse::Ok) 处理
- 新增 4 个测试用例:
- test_mock_backend_set_cursor_visible — 验证 MockBackend 处理 SetCursorVisible(true/false)
- test_mock_backend_cursor_capability — 验证 MockBackend 声明 Cursor 能力
- test_device_command_cursor_serialization — 验证 SetCursorVisible 序列化往返
- test_device_capability_cursor — 验证 DeviceCapability::Cursor 序列化
- 修复 test_mock_backend_capabilities 测试(从 2 个能力更新为 3 个)
- cargo check --workspace --all-targets 零 warning
- cargo test --workspace 全部通过77 个测试,与之前一致,因为新增 4 个测试,修复 1 个测试)
- 经验总结:
- MockBackend 是测试 DevicePlugin 的关键,无需真实硬件即可验证命令处理逻辑
- 序列化测试确保 DeviceCommand/DeviceResponse/DeviceCapability 可以安全通过 JSON/FFI 边界
- 更新 MockBackend 时需要同步更新相关的能力测试,避免断言失败
- ScreenPlugin 通过 DeviceCommand 消息与 DevicePlugin 协作,实现了松耦合的架构
