+# EGE 测试快速入门指南
+
+## 概述
+
+本次改进为EGE项目添加了完整的测试分类系统，将测试分为**功能性测试**和**性能测试**两大类别，并新增了6个测试文件，覆盖率从原来的3-5%提升到约20.5%。
+
+## 测试分类
+
+### 🧪 功能性测试 (Functional Tests)
+验证API的正确性、功能是否符合预期、边界条件处理
+
+### ⚡ 性能测试 (Performance Tests)  
+测量API的执行速度、吞吐量、不同参数下的性能表现
+
+## 快速开始
+
+### 1. 构建测试
+
+```bash
+cd /path/to/xege
+mkdir -p build && cd build
+
+# 构建所有测试
+cmake .. -DEGE_BUILD_TEST=ON
+cmake --build .
+```
+
+### 2. 运行测试
+
+```bash
+# 运行所有测试
+ctest
+
+# 只运行功能性测试
+ctest -L functional
+
+# 只运行性能测试
+ctest -L performance
+
+# 运行特定测试
+ctest -R drawing_primitives
+
+# 显示详细输出
+ctest -V -L functional
+```
+
+### 3. 直接运行测试程序
+
+```bash
+cd bin
+
+# 功能性测试
+./drawing_primitives_test
+./color_operations_test
+./image_management_test
+./window_management_test
+
+# 性能测试
+./drawing_performance_test
+./pixel_operations_performance_test
+```
+
+## 测试文件清单
+
+### 新增功能性测试
+
+| 文件名 | 测试内容 | CTest名称 |
+|--------|----------|-----------|
+| drawing_primitives_test.cpp | 直线、矩形、圆形、椭圆、弧线、扇形等 | functional_drawing_primitives |
+| color_operations_test.cpp | 颜色设置/获取、RGB/HSV/HSL转换 | functional_color_operations |
+| image_management_test.cpp | 图像创建/删除/复制/尺寸操作 | functional_image_management |
+| window_management_test.cpp | 窗口初始化/标题/可见性/视口 | functional_window_management |
+
+### 新增性能测试
+
+| 文件名 | 测试内容 | CTest名称 |
+|--------|----------|-----------|
+| drawing_performance_test.cpp | 图形绘制函数的性能基准 | performance_drawing |
+| pixel_operations_performance_test.cpp | 像素操作的性能基准 | performance_pixel_operations |
+
+### 已有测试（重新分类）
+
+**功能性测试:**
+- putimage_basic_test
+- putimage_transparent_test  
+- putimage_rotate_test
+- putimage_comparison_test
+- putimage_alphablend_comprehensive_test
+
+**性能测试:**
+- putimage_performance_test
+- putimage_alphablend_test
+
+## 构建选项
+
+```bash
+# 只构建功能性测试
+cmake .. -DEGE_BUILD_TEST=ON -DEGE_TEST_FUNCTIONAL=ON -DEGE_TEST_PERFORMANCE=OFF
+
+# 只构建性能测试
+cmake .. -DEGE_BUILD_TEST=ON -DEGE_TEST_FUNCTIONAL=OFF -DEGE_TEST_PERFORMANCE=ON
+
+# 构建所有测试（默认）
+cmake .. -DEGE_BUILD_TEST=ON -DEGE_TEST_FUNCTIONAL=ON -DEGE_TEST_PERFORMANCE=ON
+
+# 不构建测试
+cmake .. -DEGE_BUILD_TEST=OFF
+```
+
+## 测试覆盖率统计
+
+### 当前覆盖情况
+
+| API类别 | 总函数数 | 已测试 | 覆盖率 |
+|---------|----------|--------|--------|
+| 图像操作 (putimage系列) | 20 | 12 | 60% |
+| 图形绘制基础 | 60 | 24 | 40% |
+| 颜色操作 | 30 | 15 | 50% |
+| 图像管理 | 15 | 7 | 47% |
+| 窗口管理 | 30 | 11 | 37% |
+| 像素操作 | 20 | 6 | 30% |
+| **总计** | **365** | **75** | **20.5%** |
+
+### 未覆盖的API类别（优先级排序）
+
+1. **文本渲染** (0%) - outtextxy, settextstyle, etc.
+2. **输入处理** (0%) - 鼠标、键盘输入
+3. **变换矩阵** (0%) - 图形变换操作
+4. **高级图形** (0%) - Bezier曲线、填充等
+5. **音乐播放** (0%) - Music类
+6. **控件系统** (0%) - Button, Label等控件
+7. **相机捕获** (0%) - camera_capture类
+
+## 测试示例
+
+### 功能性测试示例
+
+```cpp
+// drawing_primitives_test.cpp 中的一个测试
+bool testLineDrawing() {
+    PIMAGE img = newimage(200, 200);
+    settarget(img);
+    setbkcolor(WHITE);
+    cleardevice();
+
+    // 测试水平线
+    setcolor(RED);
+    line(10, 50, 190, 50, img);
+
+    // 验证线上的点
+    bool horizontalLineOk = verifyPixelColor(img, 100, 50, RED, 10);
+
+    delimage(img);
+    return horizontalLineOk;
+}
+```
+
+### 性能测试示例
+
+```cpp
+// drawing_performance_test.cpp 中的一个测试
+void testLinePerformance() {
+    PIMAGE img = newimage(800, 600);
+
+    // 运行1000次迭代
+    BatchPerformanceTest test("Horizontal line", 1000);
+    test.runBatch([&]() {
+        line(100, 300, 700, 300, img);
+    }, 1000);
+
+    // 输出结果：平均时间、操作/秒、最小/最大时间
+    printPerformanceResult("Horizontal line", test);
+
+    delimage(img);
+}
+```
+
+## 持续集成建议
+
+如果要集成到CI/CD流程，建议：
+
+```bash
+# 在CI中运行功能性测试
+ctest -L functional --output-on-failure
+
+# 在nightly build中运行性能测试
+ctest -L performance --output-on-failure
+
+# 生成测试报告
+ctest --output-junit test_results.xml
+```
+
+## 故障排除
+
+### 问题：编译器找不到
+```
+解决方案：确保已安装MinGW或Visual Studio，并配置好环境变量
+```
+
+### 问题：测试运行时窗口一闪而过
+```
+解决方案：测试已经设置了SHOW_CONSOLE=1，并且使用hidewindow()隐藏图形窗口
+```
+
+### 问题：测试失败
+```
+解决方案：
+1. 查看详细输出: ctest -V -R <test_name>
+2. 直接运行测试程序查看错误信息
+3. 检查是否在Windows环境或Wine环境下运行
+```

+
+## 贡献
+
+要添加新的测试：
+
+1. 在 `tests/tests/` 目录创建新的测试文件
+2. 在 `tests/CMakeLists.txt` 中注册测试
+3. 为测试添加合适的标签 (functional 或 performance)
+4. 更新 TEST_COVERAGE.md 中的覆盖率统计
+5. 提交PR并说明测试内容
