visual_test.rs

  1//! Visual test platform that combines real rendering (macOs-only for now) with controllable TestDispatcher.
  2//!
  3//! This platform is used for visual tests that need:
  4//! - Real rendering (e.g. Metal/compositor) for accurate screenshots
  5//! - Deterministic task scheduling via TestDispatcher
  6//! - Controllable time via `advance_clock`
