Function runFragmentTest

runFragmentTest(t, format, fsShader, width, height, inputData, checker): Promise<void>
Runs a subgroup builtin test for fragment shaders

This test draws a full screen triangle. Tests should avoid checking the last row or column to avoid helper invocations. Underlying APIs do not consistently guarantee whether helper invocations participate in subgroup operations.
Parameters
- t: SubgroupTest
  The base test
- format: GPUTextureFormat
  The framebuffer format
- fsShader: string
  The fragment shader with the following interface: Location 0 output is framebuffer with format Group 0 binding 0 is input data
- width: number
  The framebuffer width
- height: number
  The framebuffer height
- inputData: Uint32Array | Float16Array | Float32Array
  The input data
- checker: ((data) => undefined | Error)
  A functor to check the framebuffer values
  - - (data): undefined | Error
    - Parameters
      data: Uint32Array
      Returns undefined | Error
Returns Promise<void>
- Defined in src/webgpu/shader/execution/expression/call/builtin/subgroup_util.ts:480
