Automated Testing of Shader Code
summary
Rare’s Rare Shader Test framework runs HLSL 2015 shader unit tests on top of Unreal’s test runner, dispatching compute shaders (often 1x1x1) from C++17 code, writing assertion data to a GPU readback buffer and validating on the CPU. The framework emits clear compile-time errors via emulated Concepts, requires using begin CQ test shader parameter struct for extra bindings, executes 29 tests in ~0.3s (~10 ms/test), and has an open-source HLSL2021 experiment on GitHub with CI via GitHub Actions.
