pydn-ComfyUI-to-Python-Extension/tests

Tests

This directory contains two test paths:

• unit tests for exporter behavior
• runtime validation for committed workflow fixtures

Prerequisites

• Run commands from the repo root.
• Use uv for all project commands.
• Install the repo environment first:

uv sync

• Runtime validation also needs a working ComfyUI checkout. Set COMFYUI_PATH to that checkout, or run the tests from a location where a parent directory contains ComfyUI.

Unit Tests

Run the current unit test module:

uv run python -m unittest tests.test_upscale_model_loader_export

Run all unittest-discoverable tests under tests:

uv run python -m unittest discover -s tests

Runtime Tests

The runtime harness lives at tests/runtime/run_runtime_validation.py.

Fast Tier

Fast tier validates export behavior against committed fixtures without requiring a full ComfyUI runtime for every fixture.

Run all fast-tier compatible fixtures:

uv run python tests/runtime/run_runtime_validation.py --tier fast --fixture all

Run one fixture:

uv run python tests/runtime/run_runtime_validation.py --tier fast --fixture unsafe-kwargs

Runtime Tier

Runtime tier exports inside a real ComfyUI checkout and executes generated Python for runtime-capable fixtures.

Run all runtime-capable fixtures:

uv run python tests/runtime/run_runtime_validation.py --tier runtime --fixture all

Run one runtime-capable fixture:

uv run python tests/runtime/run_runtime_validation.py --tier runtime --fixture text-to-image

Print download commands for missing models instead of failing immediately:

uv run python tests/runtime/run_runtime_validation.py --tier runtime --fixture all --print-download-plan

Runtime Fixture Names

Current committed fixtures:

• upscale-model-loader
• text-to-image
• unsafe-kwargs
• subgraph-identifiers

Notes:

• --tier runtime only runs fixtures marked runtime-capable.
• --tier fast only runs fixtures with local test mappings.

Troubleshooting

• No module named ...: run uv sync in this repo, and for runtime-tier failures also make sure the target ComfyUI checkout has its own dependencies installed.
• Could not find a valid ComfyUI checkout for runtime validation.: set COMFYUI_PATH to your ComfyUI checkout, or run the tests from a directory layout where a parent folder contains ComfyUI.
• Missing models for ...: rerun with --print-download-plan to print the expected curl commands and target model directories.
• No selected fixtures are runtime-capable for this tier.: choose a runtime-capable fixture such as text-to-image or upscale-model-loader.
• Generated script execution fails because files or models are missing: confirm the required models exist under the target ComfyUI checkout and that any staged inputs can be copied into its input/ directory.
