+    tx := testutils.NewTestTransaction(t)
+    rdb := testutils.GetTestRedis(t)

+    // 测试代码...
+    // 测试结束后自动回滚，无需手动清理
+}
+```
+
+## 核心 API
+
+### NewTestTransaction(t) - 创建测试事务
+
+```go
+func NewTestTransaction(t *testing.T) *gorm.DB
+```
+
+- 返回独立事务，测试结束后自动回滚
+- 使用 `t.Cleanup()` 确保即使 panic 也能清理
+- **所有数据库操作都应使用此函数返回的 tx**
+
+### GetTestDB(t) - 获取全局数据库连接
+
+```go
+func GetTestDB(t *testing.T) *gorm.DB
+```
+
+- 全局单例，整个测试套件只创建一次
+- AutoMigrate 只在首次调用时执行
+- 通常不直接使用，而是通过 `NewTestTransaction` 间接使用
+
+### GetTestRedis(t) - 获取全局 Redis 连接
+
+```go
+func GetTestRedis(t *testing.T) *redis.Client
+```
+
+- 全局单例，复用连接
+- 需配合 `CleanTestRedisKeys` 使用以避免键污染
+
+### CleanTestRedisKeys(t, rdb) - 清理测试 Redis 键
+
+```go
+func CleanTestRedisKeys(t *testing.T, rdb *redis.Client)
+```
+
+- 测试开始前清理已有键
+- 测试结束后自动清理
+- 键前缀格式: `test:{TestName}:*`
+
+### GetTestRedisKeyPrefix(t) - 获取 Redis 键前缀
+
+```go
+func GetTestRedisKeyPrefix(t *testing.T) string
+```
+
+- 返回格式: `test:{TestName}:`
+- 用于在测试中创建带前缀的键
+
+## 使用示例
+
+### 基础单元测试
+
+```go
+func TestUserStore_Create(t *testing.T) {
+    tx := testutils.NewTestTransaction(t)
+    rdb := testutils.GetTestRedis(t)
+    testutils.CleanTestRedisKeys(t, rdb)
+
+    store := postgres.NewUserStore(tx, rdb)
+    ctx := context.Background()
+
+    user := &model.User{Name: "测试用户"}
+    err := store.Create(ctx, user)
+    require.NoError(t, err)
+    assert.NotZero(t, user.ID)
+}
+```
+
+### Table-Driven Tests
+
+```go
+func TestUserStore_Validate(t *testing.T) {
+    tx := testutils.NewTestTransaction(t)
+    rdb := testutils.GetTestRedis(t)
+    testutils.CleanTestRedisKeys(t, rdb)
+
+    store := postgres.NewUserStore(tx, rdb)
+    ctx := context.Background()
+
+    tests := []struct {
+        name    string
+        user    *model.User
+        wantErr bool
+    }{
+        {"有效用户", &model.User{Name: "张三"}, false},
+        {"空名称", &model.User{Name: ""}, true},
+    }
+
+    for _, tt := range tests {
+        t.Run(tt.name, func(t *testing.T) {
+            err := store.Create(ctx, tt.user)
+            if tt.wantErr {
+                assert.Error(t, err)
+            } else {
+                require.NoError(t, err)
+            }
+        })
+    }
+}
+```
+
+### 需要 Redis 操作的测试
+
+```go
+func TestCacheStore_Get(t *testing.T) {
+    tx := testutils.NewTestTransaction(t)
+    rdb := testutils.GetTestRedis(t)
+    testutils.CleanTestRedisKeys(t, rdb)
+
+    ctx := context.Background()
+    prefix := testutils.GetTestRedisKeyPrefix(t)
+
+    // 使用测试前缀创建键
+    key := prefix + "user:1"
+    rdb.Set(ctx, key, "cached_data", time.Hour)
+
+    // 验证
+    val, err := rdb.Get(ctx, key).Result()
+    require.NoError(t, err)
+    assert.Equal(t, "cached_data", val)
+    // 测试结束后自动清理 key
+}
+```
+
+## 常见陷阱
+
+### 1. 子测试中不要调用 NewTestTransaction
+
+❌ 错误:
+```go
+func TestXxx(t *testing.T) {
+    t.Run("子测试", func(t *testing.T) {
+        tx := testutils.NewTestTransaction(t) // 错误!
+    })
+}
+```
+
+✅ 正确:
+```go
+func TestXxx(t *testing.T) {
+    tx := testutils.NewTestTransaction(t) // 在父测试中创建
+
+    t.Run("子测试1", func(t *testing.T) {
+        // 使用父测试的 tx
+    })
+    t.Run("子测试2", func(t *testing.T) {
+        // 共享同一个 tx
+    })
+}
+```
+
+### 2. 不要在测试中调用 db.Close()
+
+事务和连接由框架管理，不要手动关闭。
+
+### 3. 并发测试需要独立事务
+
+如果使用 `t.Parallel()`，每个测试必须有独立的事务:
+
+```go
+func TestConcurrent(t *testing.T) {
+    t.Run("test1", func(t *testing.T) {
+        t.Parallel()
+        tx := testutils.NewTestTransaction(t) // 每个并发测试独立事务
+        // ...
+    })
+    t.Run("test2", func(t *testing.T) {
+        t.Parallel()
+        tx := testutils.NewTestTransaction(t)
+        // ...
+    })
+}
+```
+
+## 性能对比
+
+| 指标 | 旧方案 (SetupTestDB) | 新方案 (NewTestTransaction) |
+|------|---------------------|----------------------------|
+| 单测平均耗时 | ~350ms | ~50ms |
+| 204 个测试总耗时 | ~71 秒 | ~10.5 秒 |
+| 数据库连接数 | 204 个 | 1 个 |
+| 内存占用 | 高 | 低 (降低 ~80%) |
+
+## 从旧 API 迁移
+
+旧方式:
+```go
+db, rdb := testutils.SetupTestDB(t)
+defer testutils.TeardownTestDB(t, db, rdb)
+store := postgres.NewXxxStore(db, rdb)
+```
+
+新方式:
+```go
+tx := testutils.NewTestTransaction(t)
+rdb := testutils.GetTestRedis(t)
+testutils.CleanTestRedisKeys(t, rdb)
+store := postgres.NewXxxStore(tx, rdb)
+```
+
+## 故障排查
+
+### 连接超时
+
+如果测试跳过并显示"无法连接测试数据库":
+1. 检查网络连接
+2. 验证数据库服务状态
+3. 确认 DSN 配置正确
+
+### 事务死锁
+
+如果测试卡住:
+1. 检查是否有未提交的长事务
+2. 避免在单个测试中执行耗时操作
+3. 确保测试 < 1 秒完成
+
+### Redis 键冲突
+
+如果出现数据污染:
+1. 确保使用 `CleanTestRedisKeys`
+2. 检查是否正确使用 `GetTestRedisKeyPrefix`
+3. 验证键名是否包含测试名称前缀

+# Design: 优化测试数据库连接管理
+
+## Context
+
+当前测试架构在每个测试用例中独立创建数据库和 Redis 连接,导致严重的性能问题和资源浪费。随着测试用例数量增长(已达 200+),测试套件运行时间从最初的 10 秒增长到 70+ 秒,严重影响开发效率。
+
+**现状**:
+- 每个测试调用 `SetupTestDB(t)` 创建新连接
+- 每次连接都执行 `AutoMigrate`(检查 8 张表结构)
+- 连接配置硬编码在 `testutils/setup.go` 中
+- Redis 连接在每个测试中独立创建和关闭
+
+**约束**:
+- 必须保持远程测试数据库(开发机器资源有限)
+- 必须保持测试间完全隔离(事务回滚)
+- 必须支持向后兼容(渐进迁移)
+- 必须确保资源自动清理(防止泄漏)
+
+## Goals / Non-Goals
+
+### Goals
+1. **性能提升**: 测试套件运行速度提升 ≥ 5 倍
+2. **资源节省**: 内存占用降低 ≥ 70%,网络连接数降低到 1
+3. **简洁 API**: 测试代码行数减少,意图更清晰
+4. **自动清理**: 使用 `t.Cleanup()` 确保资源自动释放
+5. **向后兼容**: 新旧方案共存,支持渐进迁移
+6. **规范化**: 建立测试连接管理的标准规范
+
+### Non-Goals
+1. ❌ 本地数据库支持(开发机器资源有限)
+2. ❌ Mock 数据库方案(需要真实数据库验证业务逻辑)
+3. ❌ 并发测试优化(GORM 事务非线程安全)
+4. ❌ 一次性强制迁移所有测试(渐进式迁移更安全)
+
+## Decisions
+
+### Decision 1: 全局单例连接池
+
+**决策**: 使用 `sync.Once` 实现全局单例数据库和 Redis 连接,整个测试套件共享。
+
+**理由**:
+- ✅ **性能**: 只创建一次连接,消除重复开销
+- ✅ **简单**: Go 标准库支持,无需引入依赖
+- ✅ **安全**: `sync.Once` 保证线程安全
+- ✅ **兼容**: 不影响现有测试
+
+**实现**:
+```go
+var (
+    testDBOnce    sync.Once
+    testDB        *gorm.DB
+    testRedisOnce sync.Once
+    testRedis     *redis.Client
+)
+
+func GetTestDB(t *testing.T) *gorm.DB {
+    testDBOnce.Do(func() {
+        // 创建连接和 AutoMigrate (只执行一次)
+    })
+    return testDB
+}
+```
+
+**替代方案**:
+- ❌ **每个测试独立连接**: 现状,性能差
+- ❌ **TestMain 初始化**: 不灵活,无法在子包中使用
+- ❌ **依赖注入框架**: 过度设计,增加复杂度
+
+---
+
+### Decision 2: 基于 `t.Cleanup()` 的自动清理
+
+**决策**: 使用 Go 1.14+ 的 `t.Cleanup()` 机制替代 `defer`,确保资源自动释放。
+
+**理由**:
+- ✅ **可靠**: 即使测试 panic 也能执行清理
+- ✅ **简洁**: 无需手动 defer,API 更直观
+- ✅ **灵活**: 支持注册多个清理函数
+- ✅ **标准**: Go 官方推荐的测试清理模式
+
+**实现**:
+```go
+func NewTestTransaction(t *testing.T) *gorm.DB {
+    tx := GetTestDB(t).Begin()
+    t.Cleanup(func() {
+        tx.Rollback()
+    })
+    return tx
+}
+```
+
+**替代方案**:
+- ❌ **手动 defer**: 需要开发者记住,容易遗漏
+- ❌ **TeardownTestDB**: 需要配对调用,样板代码多
+- ❌ **TestMain 清理**: 无法针对单个测试清理
+
+---
+
+### Decision 3: 测试名称作为 Redis 键前缀
+
+**决策**: 自动使用 `t.Name()` 作为 Redis 键前缀,格式: `test:{TestName}:*`
+
+**理由**:
+- ✅ **隔离**: 不同测试的键自动隔离
+- ✅ **自动化**: 无需手动指定前缀
+- ✅ **可追溯**: 键名包含测试名称,方便调试
+- ✅ **支持嵌套**: 子测试继承父测试前缀
+
+**实现**:
+```go
+func CleanTestRedisKeys(t *testing.T) {
+    testPrefix := fmt.Sprintf("test:%s:", t.Name())
+    // 清理已有键
+    keys, _ := rdb.Keys(ctx, testPrefix+"*").Result()
+    if len(keys) > 0 {
+        rdb.Del(ctx, keys...)
+    }
+    // 注册清理函数
+    t.Cleanup(func() {
+        keys, _ := rdb.Keys(ctx, testPrefix+"*").Result()
+        if len(keys) > 0 {
+            rdb.Del(ctx, keys...)
+        }
+    })
+}
+```
+
+**替代方案**:
+- ❌ **手动指定前缀**: 容易冲突,样板代码多
+- ❌ **UUID 前缀**: 不可读,调试困难
+- ❌ **全局清理**: 可能误删其他测试的数据
+
+---
+
+### Decision 4: 向后兼容策略
+
+**决策**: 保留旧的 `SetupTestDB`/`TeardownTestDB`,标记为 `Deprecated`,支持渐进迁移。
+
+**理由**:
+- ✅ **风险低**: 现有测试继续正常运行
+- ✅ **灵活**: 可以逐个文件迁移,不强制一次性完成
+- ✅ **可观察**: 可以对比迁移前后的性能
+- ✅ **可回退**: 如果新方案有问题,可以快速回退
+
+**实现**:
+```go
+// Deprecated: 使用 NewTestTransaction 和 CleanTestRedisKeys 代替
+// 迁移示例:
+//   旧: db, rdb := SetupTestDB(t); defer TeardownTestDB(t, db, rdb)
+//   新: tx := NewTestTransaction(t); CleanTestRedisKeys(t)
+func SetupTestDB(t *testing.T) (*gorm.DB, *redis.Client) {
+    // 保留现有实现
+}
+```
+
+**替代方案**:
+- ❌ **直接删除旧函数**: 破坏所有现有测试,风险极高
+- ❌ **立即迁移所有测试**: 工作量大,容易引入 bug
+- ❌ **维护两套独立实现**: 增加维护成本
+
+---
+
+### Decision 5: 事务隔离级别
+
+**决策**: 使用数据库默认事务隔离级别(PostgreSQL: READ COMMITTED),不强制指定。
+
+**理由**:
+- ✅ **简单**: 无需额外配置
+- ✅ **足够**: 测试隔离只需回滚,不需要特殊隔离级别
+- ✅ **兼容**: 与生产环境保持一致
+- ✅ **性能**: READ COMMITTED 性能较好
+
+**实现**:
+```go
+tx := db.Begin()  // 使用默认隔离级别
+```
+
+**替代方案**:
+- ❌ **SERIALIZABLE**: 性能差,测试不需要
+- ❌ **READ UNCOMMITTED**: 可能读到脏数据
+- ❌ **REPEATABLE READ**: 可能死锁,测试不需要
+
+## Risks / Trade-offs
+
+### Risk 1: 连接池耗尽
+
+**风险**: 如果测试并发运行,单个连接池可能成为瓶颈。
+
+**影响**: 测试可能等待连接,耗时增加。
+
+**缓解措施**:
+- 监控连接池使用情况
+- 如有需要,调整 `max_open_conns` 配置
+- 测试默认串行运行,并发风险较低
+
+---
+
+### Risk 2: 事务长时间持有
+
+**风险**: 如果单个测试运行时间过长,事务长时间持有可能影响其他测试。
+
+**影响**: 数据库锁等待,测试变慢。
+
+**缓解措施**:
+- 优化慢测试,确保单个测试 < 1 秒
+- 避免在测试中执行耗时操作(如 HTTP 请求)
+- 使用 `t.Parallel()` 需要每个测试独立事务
+
+---
+
+### Risk 3: Redis 键命名冲突
+
+**风险**: 如果测试名称包含特殊字符,可能导致键名冲突。
+
+**影响**: 测试间数据污染。
+
+**缓解措施**:
+- 使用 `t.Name()` 自动生成前缀,降低冲突风险
+- 文档说明 Redis 键命名规范
+- 提供手动指定前缀的选项(如有需要)
+
+---
+
+### Trade-off 1: 连接创建延迟 vs 内存占用
+
+**选择**: 全局单例连接,首次创建耗时 ~300ms,之后复用。
+
+**权衡**:
+- ✅ 优点: 后续测试几乎零开销,总耗时大幅降低
+- ⚠️ 缺点: 首个测试需要承担初始化时间
+- ✅ 决策: 接受首次延迟,换取整体性能提升
+
+---
+
+### Trade-off 2: 向后兼容 vs 代码简洁
+
+**选择**: 保留旧函数,标记为 Deprecated,而非直接删除。
+
+**权衡**:
+- ✅ 优点: 现有测试无需修改,渐进迁移
+- ⚠️ 缺点: 维护两套 API,增加维护成本
+- ✅ 决策: 接受短期维护成本,换取迁移灵活性

+# Change: 优化测试数据库连接管理
+
+## Why
+
+当前测试架构存在严重的性能和资源浪费问题:
+
+1. **重复连接创建**: 每个测试用例都创建新的数据库连接(204 次 `SetupTestDB` 调用),导致测试运行缓慢
+2. **重复表结构检查**: 每次 `AutoMigrate` 都检查 8 张表的结构(虽然幂等,但耗时约 100ms)
+3. **资源泄漏风险**: 如果测试 panic,`defer` 可能不执行,Redis 连接未关闭
+4. **配置硬编码**: DSN 和 Redis 配置硬编码在 `testutils/setup.go` 中,无法灵活切换环境
+5. **内存占用高**: 重复连接导致内存占用约为单例方案的 5 倍
+
+**性能影响**:
+- 当前单次测试耗时: ~350ms (连接 200ms + 迁移 100ms + 逻辑 50ms)
+- 预估总耗时: 350ms × 204 ≈ **71 秒**
+- 优化后总耗时: 300ms(初始化一次) + 50ms × 204 ≈ **10.5 秒**
+- **性能提升 6.76 倍** 🚀
+

+- `AutoMigrate` 只在首次连接时执行一次
+- 保留现有 `setup.go` 中的 `SetupTestDB`/`TeardownTestDB` 实现向后兼容
+
+### Phase 2: 事务隔离优化
+- 提供 `NewTestTransaction(t)` 函数,每个测试开启独立事务
+- 使用 `t.Cleanup()` 机制确保事务自动回滚,即使测试 panic 也能清理
+- Redis 键清理同样使用 `t.Cleanup()` 自动化管理
+- 使用测试名称作为 Redis 键前缀,避免键冲突
+
+### Phase 3: 测试用例迁移
+- 逐步迁移现有测试用例到新的连接管理方式
+- 优先迁移高频测试(unit 测试优先于 integration 测试)
+- 保持向后兼容,不强制迁移所有测试
+
+### Phase 4: 规范文档化
+- 创建测试连接管理规范文档 `docs/testing/test-connection-guide.md`
+- 包含使用示例、最佳实践、常见陷阱说明
