AustinMroz 5897e00793 Fix disconnection of subgraphInput links (#6258)
`LLink.disconnect` is intended to cleanup only the link itself. #4800
mistakenly assumed that it would perform all required steps for
disconnection. Later, #5015 would partially resolve this by adding some
of the missing functionality into `LLink.disconnect`, but this still
left output cleanup unhandled and failed to call
`node.onConnectionsChanged`.

This PR instead moves the disconnection code to call the function that
already has robust handling for these items and removes the
no-longer-needed and potentially misleading workaround.

Resolves #6247

Also un-skipped several SubgraphIO tests. They appear to function fine.
I'm assuming the reasons for them being skipped have been resolved.

LiteGraph Tests

This directory contains the test suite for the LiteGraph library.

Structure

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
