Adds regression tests demonstrating that V3 DynamicCombo widget
serialization breaks when nodes are packed into subgraphs. The
serializeValue callback is lost during subgraph conversion, causing
sampling_mode to serialize as the raw string 'on' instead of the
expected {sampling_mode: 'on', temperature: 0.7, top_k: 64} object.
This reproduces the bug where TextGenerateLTX2Prompt -> PreviewAny
text preview fails inside subgraphs.
Tests:
- Unit: graphToPrompt DynamicCombo serialization at top level (pass)
and inside subgraph (intentional fail)
- E2E: DynamicCombo text preview at top level and inside subgraph
- Devtools: Mock V3 DynamicCombo node for CI testing (no model needed)
ComfyUI DevTools
This directory contains development tools and test utilities for ComfyUI, previously maintained as a separate repository at https://github.com/Comfy-Org/ComfyUI_devtools.
Contents
__init__.py- Server endpoints for development tools (/api/devtools/*)dev_nodes.py- Development and testing nodes for ComfyUIfake_model.safetensors- Test fixture for model loading tests
Purpose
These tools provide:
- Test endpoints for browser automation
- Development nodes for testing various UI features
- Mock data for consistent testing environments
Usage
During CI/CD, these files are automatically copied to the ComfyUI custom_nodes directory. For local development, copy these files to your ComfyUI installation:
cp -r tools/devtools/* /path/to/your/ComfyUI/custom_nodes/ComfyUI_devtools/
Migration
This directory was created as part of issue #4683 to merge the ComfyUI_devtools repository into the main frontend repository, eliminating the need for separate versioning and simplifying the development workflow.
