Simple objects are defined here as objects that do not already have a destroy or destroy-like API available. They include: - BindGroups - ComputePipelines - PipelineLayouts - RenderPipelines - Samplers - ShaderModules - SwapChains Changes include: - Adds necessary constructors for testing and caching - Adding mock objects, mock constructors, and tests Bug: dawn:628 Change-Id: I26a5e37bc5580b9064db299a75ef1243521b266a Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/65864 Commit-Queue: Loko Kung <lokokung@google.com> Reviewed-by: Austin Eng <enga@chromium.org>
