GraphicsFuzz is a testing framework for shader compilers

GraphicsFuzz provides tools to automatically find and simplify bugs in graphics shader compilers. It operates on GLSL shaders, and uses glslangValidator and spirv-tools to additionally target SPIR-V.

Tools

  • glsl-reduce: a stand-alone GLSL shader reducer
  • glsl-fuzz: a family of tools for testing GLSL shader compilers using randomized metamorphic testing
