LiteGraph Tests

This directory contains the test suite for the LiteGraph library.

Structure

├── core/           # Core functionality tests (LGraph, LGraphNode, etc.)
├── 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
