AustinMroz 248929c655 When moving subgraphInput link, properly disconnect old link (#7229)
When moving an existing link with subgraphInput as source to a new node,
the prior link is removed, but the previous target node would not have
it's link property cleared.

Resolves #7225

Also re-enables several functional skipped tests.

It feels like I'm having to play whack-a-mole reimplementing the same
fixes on every permutation of subgraphIO links. I'd like to setup up a
unified test set that covers them all, but wouldn't want the added work
to further delay this fix.

LiteGraph Tests

This directory contains the test suite for the LiteGraph library.

Structure

├── canvas/         # Canvas-related tests (rendering, interactions)

Running Tests

# Run all litegraph tests
pnpm test:unit -- tests-ui/tests/litegraph/

# Run specific subdirectory
pnpm test:unit -- tests-ui/tests/litegraph/core/

# Run single test file
pnpm test:unit -- tests-ui/tests/litegraph/core/LGraph.test.ts

Migration Status

These tests were migrated from src/lib/litegraph/test/ to centralize test infrastructure. Currently, some tests are marked with .skip due to import/setup issues that need to be resolved.

TODO: Fix Skipped Tests

The following test files have been temporarily disabled and need fixes:

  • Most subgraph tests (circular dependency issues)
  • Some core tests (missing test utilities)
  • Canvas tests (mock setup issues)

See individual test files marked with // TODO: Fix these tests after migration for specific issues.

Writing New Tests

  1. Always import from the barrel export to avoid circular dependencies:

    import { LGraph, LGraphNode } from '@/lib/litegraph/src/litegraph'
    
  2. Use the test fixtures from fixtures/ directory

  3. Follow existing patterns for test organization

Test Fixtures

Test fixtures and helpers are located in the fixtures/ directory:

  • testExtensions.ts - Custom vitest extensions
  • subgraphHelpers.ts - Helpers for creating test subgraphs
  • subgraphFixtures.ts - Common subgraph test scenarios
  • assets/ - Test data files
