Amber is a multi-API shader test framework.

Amber lets you capture and communicate shader bugs with the fluidity and ease of a scripting flow:

* No graphics API programming is required.
  * WIP: Supports Vulkan and [Dawn][Dawn] graphics APIs.
* A single text string (or file) maps to a single graphics API pipeline test case.  The text includes:
  * Input data, including buffers and images.
  * Shaders.
  * Expectations for the result of running the pipeline.
* Shaders can be expressed in binary form (as hex), in SPIR-V assembly, or in a higher level shader language.
* After executing the pipeline, result buffers and images can be saved to output files.
