They are iterated by the test framework at runtime.See `examples.spec.ts` for basic examples of how this behaves.- {@link common/framework/params_builder!CaseParamsBuilder}:`ParamsBuilder` for adding "cases" to a test.- {@link common/framework/params_builder!CaseParamsBuilder#beginSubcases}:"Finalizes" the `CaseParamsBuilder`, returning a `SubcaseParamsBuilder`.- {@link common/framework/params_builder!SubcaseParamsBuilder}:`ParamsBuilder` for adding "subcases" to a test.### Fixtures(Uncheck the "Inherited" box to hide inherited methods from documentation pages.)- {@link common/framework/fixture!Fixture}: Base fixture for all tests.- {@link webgpu/gpu_test!GPUTest}: Base fixture for WebGPU tests.- {@link webgpu/api/validation/validation_test!ValidationTest}: Base fixture for WebGPU validation tests.- {@link webgpu/shader/validation/shader_validation_test!ShaderValidationTest}: Base fixture for WGSL shader validation tests.- {@link webgpu/idl/idl_test!IDLTest}:Base fixture for testing the exposed interface is correct (without actually using WebGPU).### WebGPU Helpers- {@link webgpu/capability_info}: Structured information about texture formats, binding types, etc.- {@link webgpu/constants}:Constant values (needed anytime a WebGPU constant is needed outside of a test function).- {@link webgpu/util/texture}: Helpers for GPUTextures.- {@link webgpu/util/unions}: Helpers for various union typedefs in the WebGPU spec.- {@link webgpu/util/math}: Helpers for common math operations.- {@link webgpu/util/check_contents}: Check the contents of TypedArrays, with nice messages.Also can be composed with {@link webgpu/gpu_test!GPUTest#expectGPUBufferValuesPassCheck}, used to implementGPUBuffer checking helpers in GPUTest.- {@link webgpu/util/conversion}: Numeric encoding/decoding for float/unorm/snorm values, etc.- {@link webgpu/util/copy_to_texture}:Helper class for copyToTexture test suites for execution copy and check results.- {@link webgpu/util/color_space_conversion}:Helper functions to do color space conversion. The algorithm is the same as defined inCSS Color Module Level 4.- {@link webgpu/util/create_elements}:Helpers for creating web elements like HTMLCanvasElement, OffscreenCanvas, etc.- {@link webgpu/util/shader}: Helpers for creating fragment shader based on intended output values, plainType, and componentCount.- {@link webgpu/util/prng}: Seed-able deterministic pseudo random number generator. Replacement for Math.random().- {@link webgpu/util/texture/base}: General texture-related helpers.- {@link webgpu/util/texture/data_generation}: Helper for generating dummy texture data.- {@link webgpu/util/texture/layout}: Helpers for working with linear image data(like in copyBufferToTexture, copyTextureToBuffer, writeTexture).- {@link webgpu/util/texture/subresource}: Helpers for working with texture subresource ranges.- {@link webgpu/util/texture/texel_data}: Helpers encoding/decoding texel formats.- {@link webgpu/util/texture/texel_view}: Helper class to create and view texture data through various representations.- {@link webgpu/util/texture/texture_ok}: Helpers for checking texture contents.- {@link webgpu/shader/types}: Helpers for WGSL data types.- {@link webgpu/shader/execution/expression/expression}: Helpers for WGSL expression execution tests.- {@link webgpu/web_platform/util}: Helpers for web platform features (e.g. video elements).### General Helpers- {@link common/framework/resources}: Provides the path to the `resources/` directory.- {@link common/util/navigator_gpu}: Finds and returns the `navigator.gpu` object or equivalent.- {@link common/util/util}: Miscellaneous utilities.- {@link common/util/util!assert}: Assert a condition, otherwise throw an exception.- {@link common/util/util!unreachable}: Assert unreachable code.- {@link common/util/util!assertReject}, {@link common/util/util!resolveOnTimeout},{@link common/util/util!rejectOnTimeout},{@link common/util/util!raceWithRejectOnTimeout}, and more.- {@link common/util/collect_garbage}:Attempt to trigger garbage collection, for testing that garbage collection is not observable.- {@link common/util/preprocessor}: A simple template-based, non-line-based preprocessor,implementing if/elif/else/endif. Possibly useful for WGSL shader generation.- {@link common/util/timeout}: Use this instead of `setTimeout`.- {@link common/util/types}: Type metaprogramming helpers.
