Christian Byrne 0646bb368a perf: add gpu hint and transform settle to prevent rasterizing while zooming (scale transform) (#7417)
## Summary

Ensures the nodes get their own compositing layers during scale
transform (tracked via mouse wheel events), which prevents rasterization
during transform. Adds forced reflow at end of transform to ensure
layers are always at correct resolution (fixes blurriness and some
readability issues).

Videos show testing this branch first then testing main - doing layer
visualization, paint (include paint operations calculations and actual
raster) visualizations, and cpu usage monitoring.

ComfyUI Frontend Testing Guide

This guide provides an overview of testing approaches used in the ComfyUI Frontend codebase. These guides are meant to document any particularities or nuances of writing tests in this codebase, rather than being a comprehensive guide to testing in general. By reading these guides first, you may save yourself some time when encountering issues.

Testing Documentation

Documentation for unit tests is organized into three guides:

Testing Structure

The ComfyUI Frontend project uses a mixed approach to unit test organization:

  • Component Tests: Located directly alongside their components with a .spec.ts extension
  • Unit Tests: Located in the tests-ui/tests/ directory
  • Store Tests: Located in the tests-ui/tests/store/ directory
  • Browser Tests: These are located in the browser_tests/ directory. There is a dedicated README in the browser_tests/ directory, so it will not be covered here.

Test Frameworks and Libraries

Our tests use the following frameworks and libraries:

Getting Started

To run the tests locally:

# Run unit tests
pnpm test:unit

# Run unit tests in watch mode
pnpm test:unit:dev

Refer to the specific guides for more detailed information on each testing type.
