+
+## 快速开始
+
+### 1. 安装测试依赖
+
+```bash
+pip install -r requirements-test.txt
+```
+
+### 2. 运行测试
+
+使用测试运行器脚本：
+
+```bash
+# 运行所有测试
+python run_tests.py all --coverage
+
+# 只运行单元测试
+python run_tests.py unit --coverage --html-report
+
+# 只运行集成测试
+python run_tests.py integration
+
+# 运行特定特效测试
+python run_tests.py effects --effect zoom
+
+# 运行压力测试
+python run_tests.py stress
+```
+
+或直接使用 pytest：
+
+```bash
+# 运行所有测试
+pytest tests/ -v --cov=entity --cov=services
+
+# 只运行单元测试
+pytest tests/test_effects/ tests/test_ffmpeg_builder/ -v
+
+# 只运行集成测试
+pytest tests/test_integration/ -v -m integration
+
+# 生成覆盖率报告
+pytest tests/ --cov=entity --cov=services --cov-report=html
+```
+
+## 测试类型说明
+
+### 单元测试 (Unit Tests)
+
+位置：`tests/test_effects/`, `tests/test_ffmpeg_builder/`
+
+测试内容：
+- 各个特效处理器的参数验证
+- FFmpeg 滤镜参数生成
+- 特效注册表功能
+- FFmpeg 命令构建逻辑
+
+特点：
+- 运行速度快
+- 不依赖外部工具
+- 测试覆盖率高
+
+### 集成测试 (Integration Tests)
+
+位置：`tests/test_integration/`
+
+测试内容：
+- 实际 FFmpeg 命令执行
+- 视频文件处理验证
+- 特效组合效果测试
+- 错误处理验证
+
+依赖：
+- 需要系统安装 FFmpeg
+- 需要测试视频文件
+
+### 压力测试 (Stress Tests)
+
+测试内容：
+- 大量特效链处理
+- 长时间运行稳定性
+- 资源使用情况
+
+运行条件：
+- 设置环境变量 `RUN_STRESS_TESTS=1`
+- 较长的超时时间
+
+## 测试配置
+
+### pytest 配置
+
+在 `pytest.ini` 中配置：
+- 测试路径和文件模式
+- 覆盖率设置
+- 标记定义
+- 输出格式
+
+### 环境变量
+
+- `RUN_STRESS_TESTS`: 启用压力测试
+- `FFMPEG_PATH`: 自定义 FFmpeg 路径
+
+## 特效测试详解
+
+### 缩放特效 (ZoomEffect)
+
+测试用例：
+- 有效参数验证：`"0,2.0,3.0"`（开始时间，缩放因子，持续时间）
+- 无效参数处理：负值、非数字、参数不足
+- 静态缩放：持续时间为 0
+- 动态缩放：指定时间段内的缩放
+- 位置 JSON 解析：自定义缩放中心点
+
+生成滤镜格式：
+```
+# 静态缩放
+[0:v]trim=start=0,zoompan=z=2.0:x=iw/2:y=ih/2:d=1[v_eff1]
+
+# 动态缩放
+[0:v]zoompan=z=if(between(t\,0\,3.0)\,2.0\,1):x=iw/2:y=ih/2:d=1[v_eff1]
+```
+
+### 变速特效 (SpeedEffect)
+
+测试用例：
+- 加速效果：`"2.0"`（2倍速）
+- 减速效果：`"0.5"`（0.5倍速）
+- 无效参数：零值、负值、非数字
+- 默认处理：空参数或 1.0 倍速
+
+生成滤镜格式：
+```
+[0:v]setpts=2.0*PTS[v_eff1]
+```
+
+## FFmpeg 命令构建测试
+
+### 测试场景
+
+1. **单文件复制**：直接复制无需编码
+2. **多文件拼接**：使用 concat 滤镜
+3. **特效处理**：复杂滤镜链构建
+4. **错误处理**：缺失文件、无效参数
+
+### 命令验证
+
+使用 `FFmpegValidator` 验证：
+- 命令结构完整性
+- 输入输出文件存在
+- 滤镜语法正确性
+- 流标识符格式
+
+## 集成测试详解
+
+### 真实 FFmpeg 执行
+
+测试流程：
+1. 创建测试视频文件
+2. 构建 FFmpeg 命令
+3. 执行命令并检查返回码
+4. 验证输出文件存在且有效
+
+### 测试用例
+
+- 简单复制操作
+- 单特效处理
+- 多特效组合
+- 视频拼接
+- 错误情况处理
+
+### 性能测试
+
+监控指标：
+- 执行时间
+- 内存使用
+- 文件大小
+- 处理速度
+
+## 代码覆盖率
+
+目标覆盖率：≥ 70%
+
+覆盖范围：
+- `entity/` 目录下的所有模块
+- `services/` 目录下的所有模块
+
+报告格式：
+- XML 格式：用于 Jenkins CI/CD
+- HTML 格式：用于本地查看
+- 终端输出：实时查看缺失覆盖
+
+## CI/CD 集成
+
+### Jenkins Pipeline
+
+配置文件：`Jenkinsfile`
+
+阶段：
+1. 环境准备
+2. 代码质量检查
+3. 单元测试
+4. 集成测试
+5. 完整测试套件
+6. 性能测试
+
+报告生成：
+- JUnit XML 测试报告
+- Cobertura 覆盖率报告
+- HTML 测试和覆盖率报告
+
+### 自动化触发
+
+- 代码提交时运行单元测试
+- PR 创建时运行完整测试
+- 主分支更新时运行包含性能测试的完整套件
+
+## 故障排除
+
+### 常见问题
+
+1. **FFmpeg 未找到**
+   ```bash
+   # 安装 FFmpeg
+   sudo apt-get install ffmpeg  # Ubuntu/Debian
+   brew install ffmpeg          # macOS
+   ```
+
+2. **测试视频创建失败**
+   ```bash
+   # 手动创建测试视频
+   python run_tests.py setup
+   ```
+
+3. **覆盖率过低**
+   - 检查是否有未测试的代码路径
+   - 添加边界条件测试
+   - 验证测试是否实际运行
+
+4. **集成测试超时**
+   - 增加超时时间：`--timeout=600`
+   - 使用更小的测试文件
+   - 检查系统资源使用情况
+
+### 调试技巧
+
+1. **查看详细输出**：
+   ```bash
+   pytest tests/ -v -s
+   ```
+
+2. **只运行失败的测试**：
+   ```bash
+   pytest tests/ --lf
+   ```
+
+3. **停在第一个失败**：
+   ```bash
+   pytest tests/ -x
+   ```
+
+4. **查看覆盖率详情**：
+   ```bash
+   pytest tests/ --cov=entity --cov-report=term-missing
+   ```
+
+## 贡献指南
+
+### 添加新测试
+
+1. 在相应目录创建测试文件
+2. 使用描述性的测试函数名
+3. 添加适当的测试标记
+4. 更新文档说明
+
+### 测试最佳实践
+
+1. **独立性**：每个测试应该独立运行
+2. **可重复性**：测试结果应该一致
+3. **清晰性**：测试意图应该明确
+4. **完整性**：覆盖正常和异常情况
+
+### 代码质量
+
+- 遵循 PEP 8 代码风格
+- 使用类型注解
+- 添加适当的文档字符串
+- 使用有意义的变量名
