WebGPU Conformance Test Suite

This is the conformance test suite for WebGPU. It tests the behaviors defined by the WebGPU specification.

The contents of this test suite are considered normative; implementations must pass them to be WebGPU-conformant. Mismatches between the specification and tests are bugs.

This test suite can be embedded inside WPT or run in standalone.
