+
+## Testing Philosophy
+
+BitFun E2E tests focus on **user journeys** and **critical paths** to ensure the desktop application works correctly from the user's perspective. We use a layered testing approach to balance coverage and execution speed.
+
+### Key Principles
+
+1. **Test real user workflows**, not implementation details
+2. **Use data-testid attributes** for stable selectors
+3. **Follow Page Object Model** for maintainability
+4. **Keep tests independent** and idempotent
+5. **Fail fast** with clear error messages
+
+## Test Levels
+
+BitFun uses a 3-tier test classification system:
+
+### L0 - Smoke Tests (Critical Path)
+
+**Purpose**: Verify basic app functionality; must pass before any release.
+
+**Characteristics**:
+- Run time: 1-2 minutes
+- No AI interaction or workspace required
+- Can run in CI/CD
+- Tests verify UI elements exist and are accessible
+
+**When to run**: Every commit, before merge, pre-release
+
+**Test Files**:
+
+| Test File | Verification |
+|-----------|--------------|
+| `l0-smoke.spec.ts` | App startup, DOM structure, Header visibility, no critical JS errors |
+| `l0-open-workspace.spec.ts` | Workspace state detection (startup page vs workspace), startup page interaction |
+| `l0-open-settings.spec.ts` | Settings button visibility, settings panel open/close |
+| `l0-navigation.spec.ts` | Sidebar exists when workspace open, nav items visible and clickable |
+| `l0-tabs.spec.ts` | Tab bar exists when files open, tabs display correctly |
+| `l0-theme.spec.ts` | Theme attributes on root element, theme CSS variables, theme system functional |
+| `l0-i18n.spec.ts` | Language configuration, i18n system functional, translated content |
+| `l0-notification.spec.ts` | Notification service available, notification entry visible in header |
+| `l0-observe.spec.ts` | Manual observation test - keeps app window open for 60 seconds for inspection |
+
+### L1 - Functional Tests (Feature Validation)
+
+**Purpose**: Validate major features work end-to-end with real UI interactions.
+
+**Characteristics**:
+- Run time: 3-5 minutes
+- Workspace is automatically opened (tests run with actual workspace context)
+- No AI model required (tests UI behavior, not AI responses)
+- Tests verify actual user interactions and state changes
+
+**When to run**: Before feature merge, nightly builds, pre-release
+
+**Test Files**:
+
+| Test File | Verification |
+|-----------|--------------|
+| `l1-ui-navigation.spec.ts` | Header component, window controls (minimize/maximize/close), window state toggling |
+| `l1-workspace.spec.ts` | Workspace state detection, startup page vs workspace UI, window state management |
+| `l1-chat-input.spec.ts` | Chat input typing, multiline input (Shift+Enter), send button state, message clearing |
+| `l1-navigation.spec.ts` | Navigation panel structure, clicking nav items to switch views, active item highlighting |
+| `l1-file-tree.spec.ts` | File tree display, folder expand/collapse, file selection, open file in editor |
+| `l1-editor.spec.ts` | Monaco editor display, file content, tab bar, multi-tab switch/close, unsaved marker |
+| `l1-terminal.spec.ts` | Terminal container, xterm.js display, keyboard input, terminal output |
+| `l1-git-panel.spec.ts` | Git panel display, branch name, changed files list, commit input, diff viewing |
+| `l1-settings.spec.ts` | Settings button, panel open/close, settings tabs, configuration inputs |
+| `l1-session.spec.ts` | Session scene, session list in sidebar, new session button, session switching |
+| `l1-dialog.spec.ts` | Modal overlay, confirm dialogs, input dialogs, dialog close (ESC/backdrop) |
+| `l1-chat.spec.ts` | Message list display, message sending, stop button, code block rendering, streaming indicator |
+
+### L2 - Integration Tests (Full System)
+
+**Purpose**: Validate complete workflows with real AI integration.
+
+**Characteristics**:
+- Run time: 15-60 minutes
+- Requires AI provider configuration
+
+**When to run**: Pre-release, manual validation
+
+**Current Status**: L2 tests are not yet implemented
+
+**Planned Test Files**:
+
+| Test File | Verification | Status |
+|-----------|--------------|--------|
+| `l2-ai-conversation.spec.ts` | Complete AI conversation flow | Not implemented |
+| `l2-tool-execution.spec.ts` | Tool execution (Read, Write, Bash) | Not implemented |
+| `l2-multi-step.spec.ts` | Multi-step user journeys | Not implemented |
+
+## Getting Started
+
+### 1. Prerequisites
+
+Install required dependencies:
+
+```bash
+# Install tauri-driver
+cargo install tauri-driver --locked
+
+# Build the application (from project root)
+npm run desktop:build
+
+# Install E2E test dependencies
+cd tests/e2e
+npm install
+```
+
+### 2. Verify Installation
+
+Check that the app binary exists:
+
+**Windows**: `target/release/bitfun-desktop.exe`
+**Linux/macOS**: `target/release/bitfun-desktop`
+
+### 3. Run Tests
+
+```bash
+# From tests/e2e directory
+
+# Run L0 smoke tests (fastest)
+npm run test:l0
+
+# Run all L0 tests
+npm run test:l0:all
+
+# Run L1 functional tests
+npm run test:l1
+
+# Run specific test file
+npm test -- --spec ./specs/l0-smoke.spec.ts
+```
+
+### 4. Test Running Mode (Release vs Dev)
+
+The test framework supports two running modes:
+
+#### Release Mode (Default)
+- **Application Path**: `target/release/bitfun-desktop.exe`
+- **Characteristics**: Optimized build, fast startup, production-ready
+- **Use Case**: CI/CD, formal testing
+
+#### Dev Mode
+- **Application Path**: `target/debug/bitfun-desktop.exe`
+- **Characteristics**: Includes debug symbols, requires dev server (port 1422)
+- **Use Case**: Local development, rapid iteration
+
+**How to Identify Current Mode**:
+
+When running tests, check the first few lines of output:
+
+```bash
+# Release Mode Output
+application: <PROJECT_ROOT>\target\release\bitfun-desktop.exe
+
+# Dev Mode Output
+application: <PROJECT_ROOT>\target\debug\bitfun-desktop.exe
+Debug build detected, checking dev server...
+```
+
+**Core Principle**: The test framework prioritizes `target/release/bitfun-desktop.exe`. If it doesn't exist, it automatically uses `target/debug/bitfun-desktop.exe`.

+
+## Writing Tests
+
+### 1. Test File Naming
+
+Follow this convention:
+
+```
+{level}-{feature}.spec.ts
+
+Examples:
+- l0-smoke.spec.ts
+- l1-chat-input.spec.ts
+- l2-ai-conversation.spec.ts
+```
+
+### 2. Use Page Objects
+
+**Bad**:
+```typescript
+it('should send message', async () => {
+  const input = await $('[data-testid="chat-input-textarea"]');
+  await input.setValue('Hello');
+  const btn = await $('[data-testid="chat-input-send-btn"]');
+  await btn.click();
+});
+```
+
+**Good**:
+```typescript
+import { ChatPage } from '../page-objects/ChatPage';
+
+it('should send message', async () => {
+  const chatPage = new ChatPage();
+  await chatPage.sendMessage('Hello');
+});
+```
+
+### 3. Test Structure Template
+
+```typescript
+/**
+ * L1 Feature name spec: description of what this test validates.
+ */
+
+import { browser, expect } from '@wdio/globals';
+import { SomePage } from '../page-objects/SomePage';
+
+describe('Feature Name', () => {
+  const page = new SomePage();
+
+  before(async () => {
+    // Setup - runs once before all tests
+    await browser.pause(3000);
+    await page.waitForLoad();
+  });
+
+  describe('Sub-feature 1', () => {
+    it('should do something', async () => {
+      // Arrange
+      const initialState = await page.getState();
+      
+      // Act
+      await page.performAction();
+      
+      // Assert
+      const newState = await page.getState();
+      expect(newState).not.toEqual(initialState);
+    });
+  });
+
+  afterEach(async function () {
+    // Capture screenshot on failure (handled by config)
+  });
+
+  after(async () => {
+    // Cleanup
+  });
+});
+```
+
+### 4. data-testid Naming Convention
+
+Format: `{module}-{component}-{element}`
+
+**Examples**:
+```html
+<!-- Startup page -->
+<div data-testid="startup-container">
+  <button data-testid="startup-open-folder-btn">Open Folder</button>
+  <div data-testid="startup-recent-projects">...</div>
+</div>
+
+<!-- Chat -->
+<div data-testid="chat-input-container">
+  <textarea data-testid="chat-input-textarea"></textarea>
+  <button data-testid="chat-input-send-btn">Send</button>
+</div>
+
+<!-- Header -->
+<header data-testid="header-container">
+  <button data-testid="header-minimize-btn">_</button>
+  <button data-testid="header-maximize-btn">□</button>
+  <button data-testid="header-close-btn">×</button>
+</header>
+```
+
+### 5. Assertions
+
+Use clear, specific assertions:
+
+```typescript
+// Good: Specific expectations
+expect(await header.isVisible()).toBe(true);
+expect(messages.length).toBeGreaterThan(0);
+expect(await input.getValue()).toBe('Expected text');
+
+// Avoid: Vague assertions
+expect(true).toBe(true); // meaningless
+```
+
+### 6. Waits and Retries
+
+Use built-in wait utilities:
+
+```typescript
+import { waitForElementStable, waitForStreamingComplete } from '../helpers/wait-utils';
+
+// Wait for element to become stable
+await waitForElementStable('[data-testid="message-list"]', 500, 10000);
+
+// Wait for streaming to complete
+await waitForStreamingComplete('[data-testid="model-response"]', 2000, 30000);
+```
+
+## Best Practices
+
+### Do's
+
+1. **Keep tests focused** - One test, one assertion concept
+2. **Use meaningful test names** - Describe the expected behavior
+3. **Test user behavior** - Not implementation details
+4. **Handle async properly** - Always await async operations
+5. **Clean up after tests** - Reset state when needed
+6. **Log progress** - Use console.log for debugging
+7. **Use environment settings** - Centralize timeouts and retries
+
+### Don'ts
+
+1. **Don't use hard-coded waits** - Use `waitForElement` instead of `pause`
+2. **Don't share state between tests** - Each test should be independent
+3. **Don't test internal implementation** - Focus on user-visible behavior
+4. **Don't ignore flaky tests** - Fix or mark as skipped with reason
+5. **Don't use complex selectors** - Prefer data-testid
+6. **Don't test third-party code** - Only test BitFun functionality
+7. **Don't mix test levels** - Keep L0/L1/L2 separate
+
+### Conditional Tests
+
+```typescript
+it('should test feature when workspace is open', async function () {
+  const startupVisible = await startupPage.isVisible();
+  
+  if (startupVisible) {
+    console.log('[Test] Skipping: workspace not open');
+    this.skip();
+    return;
+  }
+  
+  // Test continues...
+});
+```
+
+## Troubleshooting
+
+### Common Issues
+
+#### 1. tauri-driver not found
+
+**Symptom**: `Error: spawn tauri-driver ENOENT`
+
+**Solution**:
+```bash
+# Install or update tauri-driver
+cargo install tauri-driver --locked
+
+# Verify installation
+tauri-driver --version
+
+# Ensure ~/.cargo/bin is in PATH
+echo $PATH  # macOS/Linux
+echo %PATH% # Windows
+```
+
+#### 2. App not built
+
+**Symptom**: `Application not found at target/release/bitfun-desktop.exe`
+
+**Solution**:
+```bash
+# Build the app (from project root)
+npm run desktop:build
+
+# Verify binary exists
+# Windows
+dir target\release\bitfun-desktop.exe
+# Linux/macOS
+ls -la target/release/bitfun-desktop
+```
+
+#### 3. Test timeouts
+
+**Symptom**: Tests fail with "timeout" errors
+
+**Causes**:
+- Slow app startup (debug builds are slower)
+- Element not visible yet
+- Network delays
+
+**Solutions**:
+```typescript
+// Increase timeout for specific operation
+await page.waitForElement(selector, 30000);
+
+// Add strategic waits
+await browser.pause(1000); // After clicking
+```
+
+#### 4. Element not found
+
+**Symptom**: `Element with selector '[data-testid="..."]' not found`
+
+**Debug steps**:
+```typescript
+// 1. Check if element exists
+const exists = await page.isElementExist('[data-testid="my-element"]');
+console.log('Element exists:', exists);
+
+// 2. Capture page source
+const html = await browser.getPageSource();
+console.log('Page HTML:', html.substring(0, 1000));
+
+// 3. Take screenshot
+await browser.saveScreenshot('./reports/screenshots/debug.png');
+
+// 4. Verify data-testid in frontend code
+// Check src/web-ui/src/... for the component
+```
+
+#### 5. Flaky tests
+
+**Symptoms**: Tests pass sometimes, fail other times
+
+**Common causes**:
+- Race conditions
+- Timing issues
+- State pollution between tests
+
+**Solutions**:
+```typescript
+// Use waitForElement instead of pause
+await page.waitForElement(selector);
+
+// Ensure test independence
+beforeEach(async () => {
+  await page.resetState();
+});
+```
+
+### Debug Mode
+
+Run tests with debugging enabled:
+
+```bash
+# Enable WebDriverIO debug logs
+npm test -- --spec ./specs/l0-smoke.spec.ts --log-level=debug
+```
+
+### Screenshot Analysis
+
+Screenshots are automatically saved to `tests/e2e/reports/screenshots/` on test failure.
+
+## Adding New Tests
+
+### Step-by-Step Guide
+
+1. **Identify the test level** (L0/L1/L2)
+2. **Create test file** in `specs/` directory
+3. **Add data-testid to UI elements** (if needed)
+4. **Create or update Page Objects** in `page-objects/`
+5. **Write test following template**
+6. **Run test locally** to verify
+7. **Add npm script** to `package.json` (optional)
+8. **Update config** to include new spec file
+
+### Example: Adding L1 File Tree Test
+
+1. Create `tests/e2e/specs/l1-file-tree.spec.ts`
+2. Add data-testid to file tree component:
+   ```tsx
+   <div data-testid="file-tree-container">
+     <div data-testid="file-tree-item" data-path={path}>
+   ```
+3. Create `page-objects/FileTreePage.ts`:
+   ```typescript
+   export class FileTreePage extends BasePage {
+     async getFiles() { ... }
+     async clickFile(name: string) { ... }
+   }
+   ```
+4. Write test:
+   ```typescript
+   describe('L1 File Tree', () => {
+     it('should display workspace files', async () => {
+       const files = await fileTree.getFiles();
+       expect(files.length).toBeGreaterThan(0);
+     });
+   });
+   ```
+5. Run: `npm test -- --spec ./specs/l1-file-tree.spec.ts`
+6. Update `config/wdio.conf_l1.ts` to include the new spec
+
+## CI/CD Integration
+
+### Recommended Test Strategy

+
+## 测试理念
+
+BitFun E2E 测试专注于**用户旅程**和**关键路径**，确保桌面应用从用户角度正常工作。我们使用分层测试方法来平衡覆盖率和执行速度。
+
+### 核心原则
+
+1. **测试真实的用户工作流**，而不是实现细节
+2. **使用 data-testid 属性**确保选择器稳定
+3. **遵循 Page Object 模式**提高可维护性
+4. **保持测试独立**和幂等性
+5. **快速失败**并提供清晰的错误信息
+
+## 测试级别
+
+BitFun 使用三级测试分类系统：
+
+### L0 - 冒烟测试（关键路径）
+
+**目的**：验证基本应用功能；必须在任何发布前通过。
+
+**特点**：
+- 运行时间：1-2 分钟
+- 不需要 AI 交互和工作区
+- 可在 CI/CD 中运行
+- 测试验证 UI 元素存在且可访问
+
+**何时运行**：每次提交、合并前、发布前
+
+**测试文件**：
+
+| 测试文件 | 验证内容 |
+|----------|----------|
+| `l0-smoke.spec.ts` | 应用启动、DOM结构、Header可见性、无严重JS错误 |
+| `l0-open-workspace.spec.ts` | 工作区状态检测（启动页 vs 工作区）、启动页交互 |
+| `l0-open-settings.spec.ts` | 设置按钮可见性、设置面板打开/关闭 |
+| `l0-navigation.spec.ts` | 工作区打开时侧边栏存在、导航项可见可点击 |
+| `l0-tabs.spec.ts` | 文件打开时标签栏存在、标签页正确显示 |
+| `l0-theme.spec.ts` | 根元素主题属性、主题CSS变量、主题系统功能 |
+| `l0-i18n.spec.ts` | 语言配置、国际化系统功能、翻译内容 |
+| `l0-notification.spec.ts` | 通知服务可用、通知入口在header中可见 |
+| `l0-observe.spec.ts` | 手动观察测试 - 保持窗口打开60秒用于检查 |
+
+### L1 - 功能测试（特性验证）
+
+**目的**：验证主要功能端到端工作，包含真实的UI交互。
+
+**特点**：
+- 运行时间：3-5 分钟
+- 工作区已自动打开（测试在实际工作区上下文中运行）
+- 不需要 AI 模型（测试 UI 行为，而非 AI 响应）
+- 测试验证实际用户交互和状态变化
+
+**何时运行**：特性合并前、每晚构建、发布前
+
+**测试文件**：
+
+| 测试文件 | 验证内容 |
+|----------|----------|
+| `l1-ui-navigation.spec.ts` | Header组件、窗口控制（最小化/最大化/关闭）、窗口状态切换 |
+| `l1-workspace.spec.ts` | 工作区状态检测、启动页 vs 工作区UI、窗口状态管理 |
+| `l1-chat-input.spec.ts` | 聊天输入、多行输入（Shift+Enter）、发送按钮状态、消息清空 |
+| `l1-navigation.spec.ts` | 导航面板结构、点击导航项切换视图、当前项高亮 |
+| `l1-file-tree.spec.ts` | 文件树显示、文件夹展开/折叠、文件选择、在编辑器中打开文件 |
+| `l1-editor.spec.ts` | Monaco编辑器显示、文件内容、标签栏、多标签切换/关闭、未保存标记 |
+| `l1-terminal.spec.ts` | 终端容器、xterm.js显示、键盘输入、终端输出 |
+| `l1-git-panel.spec.ts` | Git面板显示、分支名、变更文件列表、提交输入、差异查看 |
+| `l1-settings.spec.ts` | 设置按钮、面板打开/关闭、设置标签、配置输入 |
+| `l1-session.spec.ts` | 会话场景、侧边栏会话列表、新建会话按钮、会话切换 |
+| `l1-dialog.spec.ts` | 模态遮罩、确认对话框、输入对话框、对话框关闭（ESC/背景） |
+| `l1-chat.spec.ts` | 消息列表显示、消息发送、停止按钮、代码块渲染、流式指示器 |
+
+### L2 - 集成测试（完整系统）
+
+**目的**：验证完整工作流程与真实 AI 集成。
+
+**特点**：
+- 运行时间：15-60 分钟
+- 需要 AI 提供商配置
+
+**何时运行**：发布前、手动验证
+
+**当前状态**：L2 测试尚未实现
+
+**计划测试文件**：
+
+| 测试文件 | 验证内容 | 状态 |
+|----------|----------|------|
+| `l2-ai-conversation.spec.ts` | 完整AI对话流程 | 未实现 |
+| `l2-tool-execution.spec.ts` | 工具执行（Read、Write、Bash） | 未实现 |
+| `l2-multi-step.spec.ts` | 多步骤用户旅程 | 未实现 |
+
+## 快速开始
+
+### 1. 前置条件
+
+安装必需的依赖：
+
+```bash
+# 安装 tauri-driver
+cargo install tauri-driver --locked
+
+# 构建应用（从项目根目录）
+npm run desktop:build
+
+# 安装 E2E 测试依赖
+cd tests/e2e
+npm install
+```
+
+### 2. 验证安装
+
+检查应用二进制文件是否存在：
+
+**Windows**: `target/release/bitfun-desktop.exe`
+**Linux/macOS**: `target/release/bitfun-desktop`
+
+### 3. 运行测试
+
+```bash
+# 在 tests/e2e 目录下
+
+# 运行 L0 冒烟测试（最快）
+npm run test:l0
+
+# 运行所有 L0 测试
+npm run test:l0:all
+
+# 运行 L1 功能测试
+npm run test:l1
+
+# 运行特定测试文件
+npm test -- --spec ./specs/l0-smoke.spec.ts
+```
+
+### 4. 测试运行模式（Release vs Dev）
+
+测试框架支持两种运行模式：
+
+#### Release 模式（默认）
+- **应用路径**: `target/release/bitfun-desktop.exe`
+- **特点**: 优化构建、快速启动、生产就绪
+- **使用场景**: CI/CD、正式测试
+
+#### Dev 模式
+- **应用路径**: `target/debug/bitfun-desktop.exe`
+- **特点**: 包含调试符号、需要 dev server（端口 1422）
+- **使用场景**: 本地开发、快速迭代
+
+**如何识别当前使用的模式**：
+
+运行测试时，查看输出的前几行：
+
+```bash
+# Release 模式输出
+application: <PROJECT_ROOT>\target\release\bitfun-desktop.exe
+
+# Dev 模式输出
+application: <PROJECT_ROOT>\target\debug\bitfun-desktop.exe
+Debug build detected, checking dev server...
+```
+
+**核心原理**: 测试框架优先使用 `target/release/bitfun-desktop.exe`。如果不存在，则自动使用 `target/debug/bitfun-desktop.exe`。

+```
+
+## 编写测试
+
+### 1. 测试文件命名
+
+遵循此约定：
+
+```
+{级别}-{特性}.spec.ts
+
+示例：
+- l0-smoke.spec.ts
+- l1-chat-input.spec.ts
+- l2-ai-conversation.spec.ts
+```
+
+### 2. 使用 Page Objects
+
+**不好**：
+```typescript
+it('should send message', async () => {
+  const input = await $('[data-testid="chat-input-textarea"]');
+  await input.setValue('Hello');
+  const btn = await $('[data-testid="chat-input-send-btn"]');
+  await btn.click();
+});
+```
+
+**好**：
+```typescript
+import { ChatPage } from '../page-objects/ChatPage';
+
+it('should send message', async () => {
+  const chatPage = new ChatPage();
+  await chatPage.sendMessage('Hello');
+});
+```
+
+### 3. 测试结构模板
+
+```typescript
+/**
+ * L1 特性名称 spec: 此测试验证内容的描述。
+ */
+
+import { browser, expect } from '@wdio/globals';
+import { SomePage } from '../page-objects/SomePage';
+
+describe('特性名称', () => {
+  const page = new SomePage();
+
+  before(async () => {
+    // 设置 - 在所有测试前运行一次
+    await browser.pause(3000);
+    await page.waitForLoad();
+  });
+
+  describe('子特性 1', () => {
+    it('应该做某事', async () => {
+      // 准备
+      const initialState = await page.getState();
+      
+      // 执行
+      await page.performAction();
+      
+      // 断言
+      const newState = await page.getState();
+      expect(newState).not.toEqual(initialState);
+    });
+  });
+
+  afterEach(async function () {
+    // 失败时捕获截图（由配置自动处理）
+  });
+
+  after(async () => {
+    // 清理
+  });
+});
+```
+
+### 4. data-testid 命名约定
+
+格式: `{模块}-{组件}-{元素}`
+
+**示例**：
+```html
+<!-- 启动页 -->
+<div data-testid="startup-container">
+  <button data-testid="startup-open-folder-btn">打开文件夹</button>
+  <div data-testid="startup-recent-projects">...</div>
+</div>
+
+<!-- 聊天 -->
+<div data-testid="chat-input-container">
+  <textarea data-testid="chat-input-textarea"></textarea>
+  <button data-testid="chat-input-send-btn">发送</button>
+</div>
+
+<!-- 顶栏 -->
+<header data-testid="header-container">
+  <button data-testid="header-minimize-btn">_</button>
+  <button data-testid="header-maximize-btn">□</button>
+  <button data-testid="header-close-btn">×</button>
+</header>
+```
+
+### 5. 断言
+
+使用清晰、具体的断言：
+
+```typescript
+// 好: 具体的期望
+expect(await header.isVisible()).toBe(true);
+expect(messages.length).toBeGreaterThan(0);
+expect(await input.getValue()).toBe('期望的文本');
+
+// 避免: 模糊的断言
+expect(true).toBe(true); // 无意义
+```
+
+### 6. 等待和重试
+
+使用内置的等待工具：
+
+```typescript
+import { waitForElementStable, waitForStreamingComplete } from '../helpers/wait-utils';
+
+// 等待元素变稳定
+await waitForElementStable('[data-testid="message-list"]', 500, 10000);
+
+// 等待流式输出完成
+await waitForStreamingComplete('[data-testid="model-response"]', 2000, 30000);
+```
+
+## 最佳实践
+
+### 应该做的
+
+1. **保持测试专注** - 一个测试，一个断言概念
+2. **使用有意义的测试名称** - 描述预期行为
+3. **测试用户行为** - 而不是实现细节
+4. **正确处理异步** - 始终 await 异步操作
+5. **测试后清理** - 需要时重置状态
+6. **记录进度** - 使用 console.log 进行调试
+7. **使用环境设置** - 集中管理超时和重试
+
+### 不应该做的
+
+1. **不要使用硬编码等待** - 使用 `waitForElement` 而不是 `pause`
+2. **不要在测试间共享状态** - 每个测试应该独立
+3. **不要测试内部实现** - 专注于用户可见的行为
+4. **不要忽略不稳定的测试** - 修复或标记为跳过并说明原因
+5. **不要使用复杂的选择器** - 优先使用 data-testid
+6. **不要测试第三方代码** - 只测试 BitFun 功能
+7. **不要混合测试级别** - 保持 L0/L1/L2 分离
+
+### 条件测试
+
+```typescript
+it('当工作区打开时应测试功能', async function () {
+  const startupVisible = await startupPage.isVisible();
+  
+  if (startupVisible) {
+    console.log('[测试] 跳过: 工作区未打开');
+    this.skip();
+    return;
+  }
+  
+  // 测试继续...
+});
+```
+
+## 问题排查
+
+### 常见问题
+
+#### 1. tauri-driver 找不到
+
+**症状**: `Error: spawn tauri-driver ENOENT`
+
+**解决方案**:
+```bash
+# 安装或更新 tauri-driver
+cargo install tauri-driver --locked
+
+# 验证安装
+tauri-driver --version
+
+# 确保 ~/.cargo/bin 在 PATH 中
+echo $PATH  # macOS/Linux
+echo %PATH% # Windows
+```
+
+#### 2. 应用未构建
+
+**症状**: `Application not found at target/release/bitfun-desktop.exe`
+
+**解决方案**:
+```bash
+# 构建应用（从项目根目录）
+npm run desktop:build
+
+# 验证二进制文件存在
+# Windows
+dir target\release\bitfun-desktop.exe
+# Linux/macOS
+ls -la target/release/bitfun-desktop
+```
+
+#### 3. 测试超时
+
+**症状**: 测试失败并显示"timeout"错误
+
+**原因**:
+- 应用启动慢（debug 构建更慢）
+- 元素尚未可见
+- 网络延迟
+
+**解决方案**:
+```typescript
+// 增加特定操作的超时时间
+await page.waitForElement(selector, 30000);
+
+// 添加策略性等待
+await browser.pause(1000); // 点击后
+```
+
+#### 4. 元素未找到
+
+**症状**: `Element with selector '[data-testid="..."]' not found`
+
+**调试步骤**:
+```typescript
+// 1. 检查元素是否存在
+const exists = await page.isElementExist('[data-testid="my-element"]');
+console.log('元素存在:', exists);
+
+// 2. 捕获页面源码
+const html = await browser.getPageSource();
+console.log('页面 HTML:', html.substring(0, 1000));
+
+// 3. 截图
+await browser.saveScreenshot('./reports/screenshots/debug.png');
+
+// 4. 在前端代码中验证 data-testid
+// 检查 src/web-ui/src/... 中的组件
+```
+
+#### 5. 不稳定的测试
+
+**症状**: 测试有时通过，有时失败
+
+**常见原因**:
+- 竞态条件
+- 时序问题
+- 测试间状态污染
+
+**解决方案**:
+```typescript
+// 使用 waitForElement 而不是 pause
+await page.waitForElement(selector);
+
+// 确保测试独立性
+beforeEach(async () => {
+  await page.resetState();
+});
+```
+
+### 调试模式
+
+启用调试运行测试：
+
+```bash
+# 启用 WebDriverIO 调试日志
+npm test -- --spec ./specs/l0-smoke.spec.ts --log-level=debug
+```
+
+### 截图分析
+
+测试失败时，截图会自动保存到 `tests/e2e/reports/screenshots/`。
+
+## 添加新测试
+
+### 分步指南
+
+1. **确定测试级别** (L0/L1/L2)
+2. **在 `specs/` 目录创建测试文件**
+3. **向 UI 元素添加 data-testid** (如需要)
+4. **在 `page-objects/` 创建或更新 Page Objects**
+5. **按照模板编写测试**
+6. **本地运行测试**验证
+7. **在 `package.json` 添加 npm 脚本** (可选)
+8. **更新配置**以包含新的 spec 文件
+
+### 示例: 添加 L1 文件树测试
+
+1. 创建 `tests/e2e/specs/l1-file-tree.spec.ts`
+2. 向文件树组件添加 data-testid:
+   ```tsx
+   <div data-testid="file-tree-container">
+     <div data-testid="file-tree-item" data-path={path}>
+   ```
+3. 创建 `page-objects/FileTreePage.ts`:
+   ```typescript
+   export class FileTreePage extends BasePage {
+     async getFiles() { ... }
+     async clickFile(name: string) { ... }
+   }
+   ```
+4. 编写测试:
+   ```typescript
+   describe('L1 文件树', () => {
+     it('应显示工作区文件', async () => {
+       const files = await fileTree.getFiles();
+       expect(files.length).toBeGreaterThan(0);
+     });
+   });
+   ```
+5. 运行: `npm test -- --spec ./specs/l1-file-tree.spec.ts`
+6. 更新 `config/wdio.conf_l1.ts` 以包含新的 spec
+
+## CI/CD 集成

 ## Troubleshooting
 
-### 1. tauri-driver not found
-
-Ensure tauri-driver is installed and `~/.cargo/bin` is in PATH:
+### tauri-driver not found
 
 ```bash
 cargo install tauri-driver --locked
 ```
 
-### 2. App not built
-
-Build the app:
+### App not built
 
 ```bash
 npm run desktop:build
 ```
 
-### 3. Test timeout
-
-Tauri app startup can be slow; adjust timeouts in config if needed.
-
-## Adding tests
-
-1. Create a new `.spec.ts` file under `specs/`
-2. Use the Page Object pattern
-3. Add `data-testid` attributes to UI elements under test
+### Test timeout
 
-## data-testid naming
+Debug builds are slower. Adjust timeouts in config if needed.
 
-Format: `{module}-{component}-{element}`
+## More Information
 
-Examples:
-- `header-container` – header container
-- `chat-input-send-btn` – chat send button
-- `startup-open-folder-btn` – startup open folder button

 使用 WebDriverIO + tauri-driver 的 E2E 测试框架。
 
-## 前置条件
+> 完整文档请参阅 [E2E-TESTING-GUIDE.zh-CN.md](E2E-TESTING-GUIDE.zh-CN.md)
 
-### 1. 安装 tauri-driver
+## 快速开始
+
+### 1. 安装依赖
 
 ```bash
+# 安装 tauri-driver
 cargo install tauri-driver --locked
-```
 
-### 2. 构建应用
-
-```bash
-# 在项目根目录执行
+# 构建应用
 npm run desktop:build
-```
-
-确保存在 `apps/desktop/target/release/BitFun.exe`（Windows）或 `apps/desktop/target/release/bitfun`（Linux）。
-
-### 3. 安装 E2E 依赖
 
-```bash
-cd tests/e2e
-npm install
+# 安装测试依赖
+cd tests/e2e && npm install
 ```
 
-## 运行测试
-
-### 运行 L0 smoke 测试
+### 2. 运行测试
 
 ```bash
 cd tests/e2e
+
+# L0 冒烟测试 (最快)
 npm run test:l0
-```
+npm run test:l0:all
 
-### 运行所有 smoke 测试
+# L1 功能测试
+npm run test:l1
 
-```bash
-cd tests/e2e
-npm run test:smoke
+# 运行所有测试
+npm test
 ```
 
-### 运行全部测试
+## 测试级别
 
-```bash
-cd tests/e2e
-npm test
-```
+| 级别 | 目的 | 运行时间 | AI需求 |
+|------|------|----------|--------|
+| L0 | 冒烟测试 - 验证基本功能 | < 1分钟 | 不需要 |
+| L1 | 功能测试 - 验证功能特性 | 5-15分钟 | 不需要(mock) |

-## 故障排除
+## 常见问题
 
-### 1. 找不到 tauri-driver
-
-确保已安装 tauri-driver，并且 `~/.cargo/bin` 已加入 PATH：
+### tauri-driver 找不到
 
 ```bash
 cargo install tauri-driver --locked
 ```
 
-### 2. 未构建应用
-
-请先构建应用：
+### 应用未构建
 
 ```bash
 npm run desktop:build
 ```
 
-### 3. 测试超时
-
-Tauri 应用启动可能较慢；如有需要请在配置中调整超时时间。
-
-## 添加测试
-
-1. 在 `specs/` 下创建新的 `.spec.ts` 文件
-2. 使用 Page Object 模式
-3. 为被测 UI 元素添加 `data-testid` 属性
-
-## data-testid 命名
+### 测试超时
 
-格式：`{module}-{component}-{element}`
+Debug 构建启动较慢，可在配置中调整超时时间。
 
-示例：
-- `header-container` – 页头容器
-- `chat-input-send-btn` – 聊天发送按钮
-- `startup-open-folder-btn` – 启动页“打开文件夹”按钮
