Authored: 2026-01-27 13:17:28 +0800
Committed: 2026-01-27 13:17:28 +0800

Validation: Add immediate data pipeline validation tests (#4547)

• Validation: Add immediate data pipeline validation tests

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.

• Address comments

• Fix type check issues

• Add multiple immediate variables test case

• Regenerate Cache

• Clean comments and update multiple_variable cases

• Fix multiple_variable scenario

Files Added:

• src/webgpu/api/validation/encoding/programmable/pipeline_immediate.spec.ts

Files Modified:

• src/common/util/util.ts
• src/resources/cache/hashes.json
• src/resources/cache/webgpu/shader/execution/bitcast.bin
• src/webgpu/api/validation/encoding/cmds/setImmediates.spec.ts

Allow tests to extend endTestScope timeout (#4560)

• Allow tests to extend endTestScope timeout

Added a per-test endTestScope timeout function so heavy cases can extend
the time without slowing down the rest of the suite, and used it to give
the 64K timestamp-query stress test run extra headroom, avoiding flakes
while leaving the default 5000ms limit untouched elsewhere.

• Wrap the test body with pushErrorScope and popErrorScope

• review nits

Add mixed swizzle and indexing tests (#4570)

Check that a valid mix of swizzles and index works and that an invalid OOB case fails.

Add tests of swizzle assignment (#4569)

Only the single element sizzle assignment on a vector should pass. Check that some other cases continue to fail as expected. To add this test case I created a new file with a couple other simple tests since there didn't seem to be an existing validation test for simple assignment statements.
