+# Extra2D 测试套件
+
+## 概述
+
+本测试套件包含对 Extra2D 引擎核心模块的单元测试和集成测试。
+
+## 测试框架
+
+使用自定义轻量级测试框架，位于 `test_framework.h`。
+
+### 特性
+- 自动测试注册和发现
+- 支持测试套件组织
+- 丰富的断言宏
+- 详细的测试报告
+
+## 测试文件说明
+
+| 文件 | 描述 | 测试数量 |
+|------|------|----------|
+| `test_timer_module.cpp` | 定时器模块测试 | 20+ |
+| `test_event_bus.cpp` | 事件总线测试 | 20+ |
+| `test_module_registry.cpp` | 模块注册表测试 | 12+ |
+| `test_plugin_loader.cpp` | 插件加载器测试 | 15+ |
+| `test_context.cpp` | Context 集成测试 | 15+ |
+
+## 构建和运行
+
+### 构建测试
+
+```bash
+# 配置并构建测试
+xmake f --tests=y
+xmake
+
+# 或者显式指定平台
+xmake f -p mingw --tests=y
+xmake
+```
+
+### 运行测试
+
+```bash
+# 运行所有测试
+xmake run extra2d_tests
+
+# 或者在构建目录中直接运行
+./build/mingw/x86_64/debug/extra2d_tests.exe
+```
+
+## 测试覆盖范围
+
+### TimerModule 测试
+- 基础属性和生命周期
+- 一次性定时器（scheduleOnce）
+- 重复定时器（scheduleRepeat）
+- 每帧更新定时器（scheduleUpdate）
+- 暂停和恢复功能
+- 时间缩放效果
+- 多定时器管理
+- 边界条件处理
+
+### EventBus 测试
+- 基础事件广播
+- 多监听器支持
+- 监听器启用/禁用
+- 带参数事件
+- 不同事件类型
+- 监听器生命周期（RAII）
+- 输入事件（键盘、鼠标、触摸）
+- 窗口事件
+- 游戏手柄事件
+- 性能测试
+
+### ModuleRegistry 测试
+- 基础注册/注销操作
+- 重复注册处理
+- 按类型获取模块
+- 初始化和关闭顺序
+- 优先级排序
+- 空注册表处理
+
+### PluginLoader 测试
+- 基础注册/卸载操作
+- 插件加载和卸载
+- 依赖关系解析
+- 加载顺序验证
+- 缺失依赖处理
+- 循环依赖处理
+- 复杂依赖图
+
+### Context 集成测试
+- 创建和销毁
+- 初始化和关闭
+- 时间推进
+- 停止请求
+- 组件访问（模块、插件、定时器）
+- 事件广播
+- 多 Context 支持
+- 定时器集成
+- 完整生命周期
+- 性能测试
+
+## 添加新测试
+
+使用 `TEST` 宏添加新测试：
+
+```cpp
+#include "test_framework.h"
+#include <your_module.h>
+
+using namespace extra2d;
+using namespace extra2d::test;
+
+TEST(SuiteName, TestName) {
+    // 测试代码
+    ASSERT_EQ(expected, actual);
+    ASSERT_TRUE(condition);
+    ASSERT_NOT_NULL(ptr);
+}
+```
+
+## 断言宏
+
+- `ASSERT_TRUE(expr)` - 断言表达式为 true
+- `ASSERT_FALSE(expr)` - 断言表达式为 false
+- `ASSERT_EQ(expected, actual)` - 断言相等
+- `ASSERT_NE(expected, actual)` - 断言不相等
+- `ASSERT_NULL(ptr)` - 断言指针为 null
+- `ASSERT_NOT_NULL(ptr)` - 断言指针不为 null
+- `ASSERT_THROW(expr, ExceptionType)` - 断言抛出异常
+- `ASSERT_NO_THROW(expr)` - 断言不抛出异常
+
+## 注意事项
+
+1. 测试使用静态注册，自动发现并运行
+2. 每个测试用例独立运行，互不影响
+3. 测试框架会捕获异常并报告错误
+4. 支持测试跳过（skip）功能
