+# Symfony Snowflake Bundle 测试文档
+
+## 测试结构
+
+测试分为两个主要部分：
+
+1. **服务单元测试** - `Service/` 目录
+   - `ResolverFactoryTest.php` - 测试序列分配器工厂
+   - `SnowflakeTest.php` - 测试雪花ID生成器
+
+2. **集成测试** - `Integration/` 目录
+   - `IntegrationTestKernel.php` - 测试用Symfony内核
+   - `SnowflakeIntegrationTest.php` - 测试Bundle与Symfony的集成
+
+## 运行测试
+
+在项目根目录执行：
+
+```bash
+./vendor/bin/phpunit packages/symfony-snowflake-bundle/tests
+```
+
+## 测试覆盖范围
+
+### 单元测试
+- ResolverFactory
+  - 无Redis情况下使用随机序列分配器
+  - 有Redis情况下使用Redis序列分配器
+- Snowflake
+  - WorkerId生成逻辑
+  - 生成器缓存机制
+  - ID生成
+  - ID唯一性
+
+### 集成测试
+- 服务注册与自动装配
+- 在Symfony容器中生成雪花ID
+- ID唯一性验证
+
+## 贡献测试
+
+当向包添加新功能时，请确保：
+1. 为新功能编写单元测试
+2. 更新集成测试以覆盖新功能
+3. 所有现有测试仍然通过
+4. 测试覆盖率保持在高水平
