-# D3D12 Integration Tests
-
-## minimal
-**后端**: D3D12Device, DXGIFactory, CommandQueue, CommandList, SwapChain
-**内容**: 最小 D3D12 初始化流程，创建窗口和交换链，无渲染输出
-

-## triangle
-**后端**: D3D12Device, DXGIFactory, CommandQueue, CommandList, SwapChain, Buffer, Shader, RootSignature, PipelineState, RenderTargetView, DepthStencilView, Screenshot
-**内容**: 
-- 基础三角形渲染
-- 顶点 buffer 上传
-- HLSL shader 编译 (vs_5_1, ps_5_1)
-- Root signature + PSO 创建
-- RenderTarget 切换 (Present ↔ RenderTarget)
-- 截图功能验证

-## quad
-**后端**: triangle 的全部 + Texture, DescriptorHeap, ShaderResourceView
-**内容**:
-- 四边形纹理采样渲染
-- Texture 加载与初始化 (stb_image)
-- DescriptorHeap (CBV_SRV_UAV) + SRV 创建
-- 静态采样器配置
-- Root signature descriptor table
-- SetDescriptorHeaps + SetGraphicsRootDescriptorTable
-- 截图功能验证
