Description

Unifying all tests to follow Google testing convention. No real code changes

New development times (3 trials each):

Task	Initial mean ± SD (s)	Now mean ± SD (s)
Test	16.363 ± 0.512	8.230 ± 0.543
Format	7.160 ± 0.080	6.327 ± 0.146
Lint	0.160 ± 0.000	0.143 ± 0.006

Section	Updates
Testing and coding standards	Added coding and testing guidance to AGENTS.md,
Core and lifecycle	Focused tests on startup, initialization, cancellation, disposal, renderer readiness, and resource cleanup. Combined related Core and WebGPU startup tests.
UI and text editing	Removed repetitive widget, default-value, rendering-detail, and text-layout checks.
Input and gestures	Replaced SDK method mocks with real input, hand, and gesture objects.
Interaction and manipulation	Reduced repeated selection and configuration cases. Kept functional checks for capture, cancellation, scrolling, movement, rotation, resizing, and limits.
Simulator	Simplified control, environment, hand-pose, and lighting tests. Combined control-mode tests that share one setup
World, perception, and context	Reduced mock-heavy and repetitive tests across depth, object detection, anchors, scene context, camera, lighting, and video.
AI	Removed mocks. kept important query, image-generation, token, connection, cancellation, and session-cleanup behavior.
XR video layers	Combined repeated platform and lifecycle cases.
Addons	Applied a more aggressive reduction to repeated configuration, schema, mock-orchestration, and implementation checks.
Demos	Excluded demo tests from the default SDK Vitest run since it doesn't make sense to enforce SDK functionality based on demo tests.

Type of Change

• Bug fix
• New feature / enhancement
• New demo or sample
• Documentation update

Checklist

• Tested in simulator & device: Verified functionality in desktop simulator and/or physical hardware (where applicable).
• Large Assets ($\ge$ 1MB): Submitted separately to xrblocks/proprietary-assets via jsdelivr CDN.
• SDK Dynamic Dependencies: All new SDK dependencies are dynamically loaded at runtime.
• Security: Confirmed no hardcoded API keys or secrets are committed.
