+# mnote 测试参考
+
+这份文档面向 `/mnt/Data1T/mnote/scripts` 目录下的现有测试脚本，目标不是重新设计测试体系，而是把当前已经在用的 smoke、回归脚本、截图取证和人工复核方式整理成一套可执行参考。
+
+当前结论先说在前面：
+
+- `scripts/` 里的主力仍然是 `Playwright smoke + Node 断言`。
+- 对 `mnote` 来说，最有价值的不是把所有测试都换成“浏览器插件式控制”，而是把已有 smoke 的结果变得更可看、更易复核。
+- `/doko` 适合作为 smoke 之后的“真实页面直观复核层”，不是用来替代 smoke。
+
+## 1. 当前测试分层
+
+按目录里的现状，脚本大致分成四层。
+
+### 1.1 入口与网关层
+
+这一层主要验证路由、网关、owner、认证入口、基础响应是否正确，特点是快、稳定、适合作为最早执行的守门测试。
+
+代表脚本：
+
+- `task097-homepage-entry-smoke.js`
+- `task114-rust-web-gateway-entry-smoke.js`
+- `task117-next-retirement-guard.js`
+- `task159-auth-entry-smoke.js`
+
+适用场景：
+
+- 刚切流 Rust Web
+- 改了入口路由、鉴权、兼容代理
+- 需要先判断“服务有没有活着、入口是不是对的”
+
+### 1.2 页面交互 smoke 层
+
+这一层是当前最核心的 UI 验证方式：启动页面、登录测试账号、进入真实文档页或工作区，然后通过 Playwright 操作页面并做断言。
+
+代表脚本：
+
+- `task110-page-title-single-truth-smoke.js`
+- `task112-tree-rust-family-regression-smoke.js`
+- `task120-rust-web-tree-integration-smoke.js`
+- `task122-rust-web-create-page-ui-smoke.js`
+- `task163-local-folder-unified-tree-browser-smoke.js`
+- `task164-page-options-visible-effect-smoke.js`
+- `task165-rust-web-dual-pane-smoke.js`
+
+这一层已经覆盖了当前主线里最重要的部分：
+
+- tree / sidebar / create page
+- document shell / island hydration
+- 页面设置、双栏、AI、local folder
+- Rust Web 主路径
+
+### 1.3 Wolai 对标与视觉取证层
+
+这一层不是单纯判断“是否通过”，而是要保留截图、矩阵、对比结论，方便和 Wolai 体验做真实核对。
+
+代表脚本：
+
+- `task119-rust-web-wolai-visual-regression-smoke.js`
+- `task129-wolai-aline-baseline-smoke.js`
+- `task130` 到 `task137` 一系列 `wolai-aline-*`
+- `task160-wolai-page-settings-shell-smoke.js`
+- `task161-wolai-page-ai-shell-smoke.js`
+
+这一层最重要的原则不是“文案命中”，而是：
+
+- 必须有截图
+- 必须能说明视口
+- 必须能说明对比对象
+- 最终仍需要人工看图
+
+### 1.4 共享 helper 与登录/临时文档支撑层
+
+这部分决定了 smoke 是否能稳定复用。
+
+关键文件：
+
+- `tree-shell-smoke-helpers.js`
+- `task114-rust-web-gateway-entry-smoke.js`
+
+目前 helper 已经沉淀了几个稳定约定：
+
+- 默认前端入口：`MNOTE_UI_BASE_URL`，缺省 `http://127.0.0.1:3000`
+- 默认测试账号：
+  - 邮箱：`mnote.e2e@example.com`
+  - 密码：`MnoteE2E123!`
+  - 快捷按钮：`测试账号快速登录`
+- 通过 API 或 UI 兜底完成认证
+- 为 smoke 自动创建、重命名、清理临时页面
+
+后续新脚本优先复用这些 helper，不要在每个任务里再复制一套登录和清理逻辑。
+
+## 2. 当前推荐测试顺序
+
+对本项目，推荐不要一上来就跑最重的 UI 对标脚本，而是按下面顺序推进。
+
+### 2.1 第一步：入口守门
+
+先跑入口和网关类 smoke，确认不是服务没起或路由错了。
+
+建议优先：
+
+```bash
+node scripts/task114-rust-web-gateway-entry-smoke.js
+node scripts/task159-auth-entry-smoke.js
+node scripts/task097-homepage-entry-smoke.js
+```
+
+适用时机：
+
+- 本地服务刚启动
+- 刚切换分支
+- 改了认证、入口、gateway、compat
+
+### 2.2 第二步：主路径交互 smoke
+
+入口没问题后，再跑和当前改动最相关的页面交互脚本。
+
+例如：
+
+- tree / sidebar 改动：`task112`、`task120`、`task122`
+- document shell / island：`task110`、`task121`
+- 页面设置：`task160`、`task164-page-options-visible-effect-smoke.js`
+- 双栏：`task165`
+- AI：`task155`、`task156`、`task161`、`task162`
+
+原则：
+
+- 只跑和当前改动相关的脚本
+- 不要无差别全量跑
+- 先窄后宽
+
+### 2.3 第三步：截图证据复核
+
+如果脚本本身已经输出：
+
+- `screenshot`
+- `screenshotDir`
+- `measure`
+- `matrixPath`
+- `resultPath`
+
+那这些产物不应只当“附带文件”，而应作为测试结果的一部分。
+
+推荐做法：
+
+- 成功时也保留关键截图
+- 失败时至少保留失败前最后一张截图
+- 重要 UI 任务保留整组截图目录
+
+### 2.4 第四步：`/doko` 真实页面复核
+
+当 smoke 已经告诉你“逻辑大体通过”，但你仍想确认页面是否真的像人看到的一样时，再补 `/doko`。
+
+`/doko` 更适合回答这类问题：
+
+- 首屏布局是不是顺眼
+- Sidebar 层级、图标、文案是否真可读
+- 页面设置弹层是否真的展开到位
+- 登录后工作区是否像预期渲染
+
+`/doko` 不擅长替代：
+
+- 稳定断言
+- 自动点击链路
+- 大量重复回归
+
+所以推荐组合是：
+
+`smoke 先筛出通过/失败 -> 看截图 -> 必要时再用 /doko 复核真实页面`
+
+## 3. 为什么当前不建议把主线转成“浏览器插件测试”
+
+当前讨论过 `codex cli + 浏览器插件` 的方向，但对 `mnote` 现阶段的主要收益并不明显。
+
+原因有三点：
+
+1. 你当前真正缺的是“页面直观证据”，不是“替换掉 Playwright”
+2. `scripts/` 里的 smoke 已经能覆盖多数关键交互，只是证据层不够统一
+3. 浏览器插件路线更适合复用真实 Chrome 当前标签页和真实登录环境，不是当前项目测试的首要瓶颈
+
+因此，现阶段更推荐：
+
+- 保留 Playwright smoke 作为自动化骨架
+- 补足截图、trace、结果摘要
+- 用 `/doko` 做人工视角复核
+
+## 4. 新增或修改 smoke 的写法建议
+
+这里不是要求统一重构旧脚本，而是约束新增脚本尽量沿着同一条路走。
+
+### 4.1 优先复用 helper
+
+优先从下面两个文件拿能力：
+
+- `tree-shell-smoke-helpers.js`
+- `task114-rust-web-gateway-entry-smoke.js`
+
+尤其是：
+
+- 登录
+- 创建临时文档
+- 清理临时文档
+- `fetchWithTimeout`
+- `findFreePort`
+- `waitForGateway`
+
+### 4.2 让脚本输出结构化结果
+
+推荐脚本结束时输出 JSON，至少包含：
+
+```json
+{
+  "ok": true,
+  "baseUrl": "http://127.0.0.1:3000",
+  "task": "taskxxx-name",
+  "screenshot": "/abs/path/to/file.png",
+  "screenshotDir": "/abs/path/to/dir"
+}
+```
+
+如果没有截图，也应该至少输出：
+
+- `ok`
+- `baseUrl`
+- `task`
+- 关键对象 id（如 `documentId`、`workspaceId`）
+
+### 4.3 对 UI 任务默认保留截图
+
+满足下面任一条件时，建议默认保留截图：
+
+- 首屏入口变化
+- Sidebar / tree 结构变化
+- modal / popover / dropdown 变化
+- editor block 行为变化
+- Wolai 对标
+
+推荐命名方式延续现有风格：
+
+- `01-before-*`
+- `02-after-*`
+- `03-after-reload-*`
+
+这样后续人工复核时不需要重新猜步骤。
+
+### 4.4 失败信息要面向定位
+
+断言报错要直接描述“哪个状态不对”，不要只写泛化失败。
+
+推荐：
+
+- `开启宽版后 htmlWide 应为 true，实际 false`
+- `测试账号登录后仍停留在 /auth`
+- `本地首屏未捕获工作区特征`
+
+不推荐：
+
+- `smoke failed`
+- `assert error`
+
+## 5. 针对当前 mnote 的推荐组合
+
+如果后续只是做日常开发验证，推荐这样选：
+
+### 5.1 快速检查
+
+适合日常改完立刻看：
+
+```bash
+node scripts/task114-rust-web-gateway-entry-smoke.js
+node scripts/task159-auth-entry-smoke.js
+```
+
+### 5.2 主路径回归
+
+按当前改动挑 1 到 3 个最相关脚本，例如：
+
+```bash
+node scripts/task120-rust-web-tree-integration-smoke.js
+node scripts/task122-rust-web-create-page-ui-smoke.js
+node scripts/task164-page-options-visible-effect-smoke.js
+```
+
+### 5.3 视觉复核
+
+如果任务明显涉及视觉或交互形态：
+
+- 先看 smoke 产出的截图
+- 再用 `/doko` 打开真实页面复核
+
+### 5.4 Wolai 对标任务
+
+对标任务不要只看断言结果，至少补：
+
+- 本地 smoke
+- Wolai 基线截图
+- 本地截图
+- 必要时 comparison matrix
+
+## 6. 对后续演进的建议
+
+这部分不是要求本轮立刻实现，而是后续维护时优先考虑。
+
+### 6.1 在现有 smoke 上统一证据产物
+
+优先级最高的增强不是“换工具”，而是统一输出：
+
+- `tmp/.../screenshots`
+- `tmp/.../trace.zip`
+- `tmp/.../result.json`
+
+这样 smoke 从“脚本 pass/fail”升级成“脚本 + 可看证据”。
+
+### 6.2 把 `/doko` 固化成复核步骤
+
+适合写进任务流程的话术是：
+
+- 先跑 smoke
+- 再看截图
+- 仍有疑问时用 `/doko` 看真实渲染
+
+不要让 `/doko` 承担自动化断言职责。
+
+### 6.3 新脚本优先沿当前命名方式继续
+
+目前 `taskNNN-...-smoke.js` 已经形成了可追踪的任务链，后续建议继续沿用，避免引入第二套命名体系。
+
+---
+
+如果后续要继续推进，最值得做的不是重写测试体系，而是：
+
+1. 给最常用的 smoke 补统一截图/trace 产物
+2. 再补一份“如何读取 smoke 结果”的轻量脚本或汇总器
+
+这样能直接解决当前最真实的痛点：`A + C`，也就是“结果更直观、测试更像真的看过页面”。
