AustinMroz 02aaf577ec Fix inability to select image from batch in vue (#6521)
Selecting a new image from a batch sets isLoading to true, but
handleImageLoad is never triggered so the image never displays.

Swapping to a different image from a batch is currently the only place
isLoading is set to true. This change, even if temporary, results in a
good chunk of dead code.

To my understanding, ImagePreviews are always object URLs and should
never need to load, so I don't foresee the loading placeholder being
needed here.

Resolves #6458

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.
