+# ZCLAW 全系统端到端测试方案
+
+> **目标**: 设计覆盖 SaaS Admin + Tauri Desktop 的全面测试方案，验证所有功能形成闭环工作流
+> **产出物**: 测试设计文档（本文件），指导后续测试执行
+> **范围**: 功能测试 / 集成测试 / 端到端测试 / 数据一致性 / 权限验证
+
+---
+
+## Context
+
+ZCLAW 是一个三端系统：Rust 后端(10 crates) + SaaS 后端(Axum+PostgreSQL, 119 API) + Admin V2(16页面) + Tauri 桌面端(React)。当前测试基线：
+
+| 区域 | 现有测试 | 缺口 |
+|------|----------|------|
+| Rust crates | ~355 单元测试 | zclaw-saas/runtime/protocols 0 测试 |
+| TypeScript Desktop | ~255 Vitest | 覆盖核心 store，缺 Tauri IPC 层 |
+| Admin V2 | 0 测试 | Vitest 已配置但无测试文件 |
+| E2E | 5 Playwright 冒烟 | 仅 app shell 基础检查 |
+| 跨系统 | 0 | 无 Admin→SaaS→Desktop 端到端验证 |
+
+**核心问题**: 各子系统孤立测试，没有验证模块间的协同工作流。用户实际使用的是从 Admin 配置 → SaaS 存储 → Desktop 消费的完整链路。
+
+---
+
+## 一、测试基础设施搭建
+
+### 1.1 SaaS 集成测试框架
+
+**位置**: `crates/zclaw-saas/tests/`
+
+- 复用 [main.rs](crates/zclaw-saas/src/main.rs) 中 `build_router()` 构建测试 Router
+- 使用 `sqlx::test` + PostgreSQL 测试数据库（事务回滚隔离）
+- 种子数据 fixture: super_admin/admin/user 三种角色 + 基础 Provider/Model
+- 环境配置: `ZCLAW_SAAS_DEV=true` + 测试专用密钥
+
+**关键参考文件**:
+- 路由构建: [main.rs](crates/zclaw-saas/src/main.rs) `build_router()`
+- 应用状态: [state.rs](crates/zclaw-saas/src/state.rs) `AppState`
+- 错误类型: [error.rs](crates/zclaw-saas/src/error.rs) `SaasError`
+
+### 1.2 Admin V2 测试框架
+
+**位置**: `admin-v2/tests/`
+
+已有: `@testing-library/react` + `msw` + `vitest` 已配置。需搭建：
+- MSW handler 集合: 模拟 119 个 SaaS API 端点
+- 自定义 `render()` 函数（包裹 QueryClientProvider + Router）
+- 种子数据工厂函数
+
+**关键参考文件**:
+- API 层: [admin-v2/src/services/request.ts](admin-v2/src/services/request.ts)（Axios + 401 刷新）
+- 18 个 service 文件: [admin-v2/src/services/](admin-v2/src/services/)
+- 16 个页面: [admin-v2/src/pages/](admin-v2/src/pages/)
+
+### 1.3 跨系统 E2E 框架
+
+**位置**: `tests/cross-system/`
+
+- Playwright 双 target（Admin V2 + Desktop）
+- SaaS API 测试客户端（TypeScript HTTP 封装）
+- 数据库状态断言工具（直查 PostgreSQL）
+- 测试数据清理机制
+
+---
+
+## 二、功能测试（按模块）
+
+### 2.1 SaaS API — Auth 模块 (10 端点) — P0
+
+**源文件**: [crates/zclaw-saas/src/auth/handlers.rs](crates/zclaw-saas/src/auth/handlers.rs)

+| 模型解析 | Direct model→路由到 provider；Group model→failover 选择 |
+| 错误场景 | 模型不存在 404；provider 禁用 403；队列满 429 |
+| 任务管理 | user 只看自己的任务；非 admin 看他人任务 403；重试仅 failed 状态 |
+
+### 2.5 SaaS API — 其他模块
+
+| 模块 | 端点数 | 优先级 | 关键测试点 |
+|------|--------|--------|-----------|

+
+---
+
+## 三、集成测试（模块交互）
+
+### 3.1 Auth → 权限执行全覆盖 — P0
+
+**方法**: 参数化测试，角色 × 端点 × 预期状态码矩阵
+
+| 角色 | 验证策略 |
+|------|----------|
+| super_admin (admin:full) | 全部 119 端点 200/201 |
+| admin (细分权限) | 有权限 200，无权限 403 |
+| user (最小权限) | relay:use + knowledge:read + 自身信息，其余 403 |
+| 未认证 | 公开端点 200，受保护 401 |
+| API Token | zclaw_ 前缀 token 按 token 权限验证 |
+
+**核心**: [auth/mod.rs](crates/zclaw-saas/src/auth/mod.rs) 中 `auth_middleware()` 的 JWT/API Token 双路径 + `check_permission()` 的 admin:full 通配逻辑
+
+### 3.2 Admin 配置 → SaaS DB → Desktop 行为 — P0
+
+| Admin 操作 | SaaS DB 变化 | Desktop 验证 |
+|------------|-------------|-------------|
+| 新增 Provider+Model | providers/models 表新增行 | relay/models 列表包含新模型 |
+| 禁用 Provider | enabled=false | 列表不显示该 Provider 的模型 |
+| 修改用户配额 | billing_plans 更新 | relay 请求受新配额约束 |
+| 创建知识条目 | knowledge_items 新增 | Agent 能检索到新知识 |
+
+**注意**: SaaS 缓存 60s 刷新间隔，测试需等待或手动触发刷新。
+
+### 3.3 Chat 完整流程 — P0
+
+```
+Desktop (saas-relay.ts chatCompletion)
+  → POST /relay/chat/completions
+    → SaaS: 验证权限 + 配额
+    → SaaS: 解析模型(Direct/Group) → 路由到 Provider
+    → SaaS: 创建 relay_task (status=queued)
+    → SaaS: 转发到 LLM Provider (base_url)
+    → Provider: SSE 流响应
+    → SaaS: 透传 SSE + 记录 usage
+    → SaaS: relay_task status=completed
+  → Desktop: 流式显示响应
+```
+
+验证点: 每个环节的数据状态。关键文件: [relay/handlers.rs](crates/zclaw-saas/src/relay/handlers.rs), [saas-relay.ts](desktop/src/lib/saas-relay.ts)
+
+### 3.4 Memory Pipeline 闭环 — P1
+
+```
+对话 → MemoryExtractor 提取 → FTS5 全文索引 → Retriever 检索 → 注入 system prompt
+```
+
+验证: 对话后 30s(防抖) 检查 FTS5 索引内容；下次对话时 Agent 使用记忆回答。
+
+### 3.5 Pipeline 执行 — P1
+
+```
+模板加载 → YAML 解析 → DAG 依赖排序 → 节点执行 → 结果汇总
+```
+
+---
+
+## 四、端到端测试（完整业务流程）
+
+### E2E-1: 用户生命周期 — P0
+
+```
+Admin 创建用户 → 用户登录 → 查看 relay/models → 发送聊天 → 记录 usage
+→ Admin 查看 Usage 页面 → Dashboard 统计更新
+```
+
+验证: JWT 签发、relay_task 创建、billing_usage 递增、Dashboard 今日统计+1
+
+### E2E-2: Provider/Model 配置到使用 — P0
+
+```
+Admin 创建 Provider → 添加 API Key(加密存储) → 创建 Model → [等60s缓存刷新]
+→ Desktop 获取模型列表 → 使用新模型聊天 → SaaS 正确路由
+```
+
+验证: DB 中 key_value 为密文、relay_task 记录正确 provider_id
+
+### E2E-3: 知识库配置到检索 — P1
+
+```
+Admin 创建分类 → 创建知识条目(含 tags) → SaaS 生成 embedding
+→ Desktop Agent 对话中检索知识库 → 回答包含知识库内容
+```
+
+验证: knowledge_items.embedding 非空、回答内容与知识条目相关
+
+### E2E-4: 完整注册到回访 — P1
+
+```
+注册 → 登录 → auth/me → relay/models → 首次聊天 → 记忆提取(FTS5)
+→ 登出 → 登录 → 利用记忆回答
+```
+
+验证: role=user、relay_task+usage 递增、FTS5 索引、记忆引用
+
+### E2E-5: 权限变更生效 — P0
+
+```
+Admin 修改 user 角色 permissions → user 下次请求使用新权限
+→ 验证: 原来允许的端点变为 403 或原来禁止的变为 200
+```
+
+---
+
+## 五、数据一致性测试
+
+### 5.1 Admin 资源变更 → Desktop 感知 — P0
+
+| 资源 | 变更操作 | Desktop 感知 | 一致性窗口 |
+|------|----------|-------------|-----------|
+| Provider | 创建/禁用 | relay/models 列表更新 | ≤60s |
+| Model | 创建/修改 | 模型列表+详情 | ≤60s |
+| 角色权限 | 修改 permissions | 用户下次请求新权限 | 即时(JWT内嵌) |
+| 配额 | 修改 billing_plan | 下次请求新配额 | 即时 |
+
+### 5.2 计费与请求数一致性 — P0
+
+```sql
+-- 验证 relay 请求数
+SELECT COUNT(*) FROM relay_tasks WHERE account_id = $1 AND status = 'completed'
+-- 应等于
+SELECT relay_requests FROM billing_usage WHERE account_id = $1
+```
+
+| 测试点 | 验证 |
+|--------|------|
+| 成功请求计数 | billing_usage.relay_requests = 实际成功数 |
+| 失败请求不计费 | relay_task.status=failed 不增加 usage |
+| Token 用量准确 | input_tokens + output_tokens 与 LLM 返回一致 |
+| SSE 流式 token 后修正 | AggregateUsageWorker 对账后更新 |
+
+### 5.3 Dashboard 统计准确性 — P1
+
+| 统计项 | 数据源 SQL | 验证 |
+|--------|-----------|------|
+| total_accounts | `SELECT COUNT(*) FROM accounts` | 一致 |
+| active_providers | `... WHERE enabled=true` | 一致 |
+| tasks_today | `... WHERE created_at >= today` | 一致 |
+| tokens_today | `SUM(input_tokens + output_tokens)` | 一致 |
+
+### 5.4 知识搜索准确性 — P1
+
+| 输入 | 预期 |
+|------|------|
+| 精确关键词 "API Key" | 含该关键词的条目排前 |
+| 语义查询 "如何配置密钥" | "API Key 配置指南" 排前 |
+| 分类过滤 | 仅返回指定分类结果 |
+| 空结果查询 | 空列表(不报错) |
+
+---
+
+## 六、权限验证测试
+
+### 6.1 角色权限矩阵 — P0
+
+| 端点类别 | super_admin | admin | user | 未认证 |
+|----------|:-----------:|:-----:|:----:|:------:|
+| POST /auth/register | - | - | - | 200 |
+| POST /auth/login | - | - | - | 200 |
+| GET /auth/me | 200 | 200 | 200 | 401 |
+| PUT /auth/password | 200 | 200 | 200 | 401 |
+| GET /accounts | 200 | 200 | **403** | 401 |
+| POST /providers | 200 | 200* | **403** | 401 |
+| POST /models | 200 | 200* | **403** | 401 |
+| POST /relay/chat/completions | 200 | 200 | 200** | 401 |
+| POST /relay/tasks/:id/retry | 200 | 200* | **403** | 401 |
+| POST /knowledge/items | 200 | 200* | **403** | 401 |
+| GET /roles | 200 | 200 | **403** | 401 |
+
+*需要对应细分权限（provider:manage/model:manage 等）
+**需要 relay:use 权限
+
+### 6.2 Token 生命周期 — P0
+
+| 场景 | 预期 |
+|------|------|
+| Access token 2h 内 | 200 |
+| Access token 过期 | 401 |
+| Refresh token 7d 内 | 新 token 对 |
+| Refresh 一次性使用 | 第二次 401 |
+| 密码修改后旧 token | 401 (pwv 不匹配) |
+| 登出后 refresh | 401 |
+
+### 6.3 账号锁定 — P0
+
+| 步骤 | 预期 |
+|------|------|
+| 第 1-4 次错误密码 | 401, failed_login_count 递增 |
+| 第 5 次错误 | locked_until = now+15min |
+| 锁定期内正确密码 | 仍 401 |
+| 15min 后 | 登录成功, count 重置 |
+
+### 6.4 速率限制 — P1
+
+| 端点 | 限制 | 超限响应 |
+|------|------|---------|
+| POST /auth/login | 5次/分/IP | 429 |
+| POST /auth/register | 3次/小时/IP | 429 |
+| POST 端点 (通用) | RPM 配置值 | 429 |
+| GET 端点 | 无限制 | - |
+
+---
+
+## 七、实施路线图
+
+### Phase 1: P0 核心测试
+
+1. **SaaS 集成测试框架** — 搭建 test_app + 种子数据 + 事务回滚
+2. **Auth 模块全量** — 注册/登录/TOTP/锁定/Token 生命周期
+3. **权限矩阵参数化** — 119 端点 × 4 角色
+4. **Relay 模块核心** — 流式/非流式/模型解析/输入验证
+5. **Admin V2 关键页面** — Login/Accounts/Knowledge/ModelServices/Relay
+6. **E2E 用户生命周期** — 创建→登录→聊天→查看用量
+
+### Phase 2: P1 扩展测试
+
+1. Model Config / Billing / Prompt / Role 模块测试
+2. Desktop Store 补充测试
+3. 跨系统 E2E (Playwright)
+4. 计费一致性验证
+5. 知识搜索准确性
+
+### Phase 3: P2 补全测试
+
+1. Config/Telemetry/Scheduled Task 模块
+2. Admin V2 剩余页面
+3. Pipeline/Hooks 系统
+4. 性能/压力测试
+
+---
+
+## 八、风险与缓解
+
+| 风险 | 缓解 |
+|------|------|
+| SaaS 集成测试需 PostgreSQL | GitHub Actions postgres service / Docker |
+| SSE 流式测试断言难 | tokio stream 收集完整响应后断言 |
+| 缓存刷新 60s 延迟 | 测试中手动触发缓存刷新或直接调用 load_from_db |
+| TOTP 码时间敏感 | mock totp_rs 或使用已知 secret 固定码 |
+| Playwright flaky | wait_for 替代 sleep + 重试机制 |
+
+---
+
+## 九、验证方法
+
+测试完成后通过以下命令验证：
+
+```bash
+# SaaS 集成测试
+cargo test -p zclaw-saas -- --test-threads=1
+
+# Admin V2 单元测试
+cd admin-v2 && pnpm vitest run
+
+# Desktop 前端测试
+cd desktop && pnpm vitest run
+
+# E2E 测试
+pnpm test:e2e
+
+# 类型检查
+pnpm tsc --noEmit
+```
+
+**测试报告交付物**:
