Validation: Add immediate data pipeline validation tests by shaoboyan091 · Pull Request #4547 · gpuweb/cts

shaoboyan091 · 2025-12-31T06:50:02Z

Adds pipeline_immediate.spec.ts to validate immediate data usage in RenderPassEncoder, ComputePassEncoder, and RenderBundleEncoder.

Tests cover:

Required immediate data slots are set.
Unused variables do not require slots.
Pipeline creation fails if shader immediate size exceeds layout limit.
RenderBundle execution invalidates pipeline and immediate data state.

Issue: #

Requirements for PR author:

All missing test coverage is tracked with "TODO" or .unimplemented().
New helpers are /** documented */ and new helper files are found in helper_index.txt.
Test behaves as expected in a WebGPU implementation. (If not passing, explain above.)
Test have be tested with compatibility mode validation enabled and behave as expected. (If not passing, explain above.)

Requirements for reviewer sign-off:

Tests are properly located in the test tree.
Test descriptions allow a reader to "read only the test plans and evaluate coverage completeness", and accurately reflect the test code.
Tests provide complete coverage (including validation control cases). Missing coverage MUST be covered by TODOs.
Helpers and types promote readability and maintainability.

When landing this PR, be sure to make any necessary issue status updates.
