From 6e4b448b91f48193ee36b6fd622871fc628277a9 Mon Sep 17 00:00:00 2001 From: bymyself Date: Fri, 13 Jun 2025 21:12:11 -0700 Subject: [PATCH] [feat] Add comprehensive unit tests for TaskQueue operations MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add MockTaskQueue class with dependency injection for isolated testing - Test core operations: queueing, processing, batch tracking, state management - Test thread safety: concurrent access, worker lifecycle, exception handling - Test integration workflows: full task processing with WebSocket updates - Test edge cases: empty queues, invalid data, cleanup scenarios - Solve heapq compatibility by wrapping items in priority tuples - Include pytest configuration and test runner script - All 15 tests passing with proper async/threading support Testing covers: ✅ Task queueing with Pydantic validation ✅ Batch history tracking and persistence ✅ Thread-safe concurrent operations ✅ Worker thread lifecycle management ✅ WebSocket message delivery tracking ✅ State snapshots and error conditions --- pytest.ini | 13 + run_tests.py | 42 ++++ tests/README.md | 89 +++++++ tests/__init__.py | 1 + tests/test_task_queue.py | 510 +++++++++++++++++++++++++++++++++++++++ 5 files changed, 655 insertions(+) create mode 100644 pytest.ini create mode 100644 run_tests.py create mode 100644 tests/README.md create mode 100644 tests/__init__.py create mode 100644 tests/test_task_queue.py diff --git a/pytest.ini b/pytest.ini new file mode 100644 index 00000000..d93fb082 --- /dev/null +++ b/pytest.ini @@ -0,0 +1,13 @@ +[tool:pytest] +testpaths = tests +python_files = test_*.py +python_classes = Test* +python_functions = test_* +addopts = + -v + --tb=short + --strict-markers + --disable-warnings +markers = + slow: marks tests as slow (deselect with '-m "not slow"') + integration: marks tests as integration tests \ No newline at end of file diff --git a/run_tests.py b/run_tests.py new file mode 100644 index 00000000..b8b94450 --- /dev/null +++ b/run_tests.py @@ -0,0 +1,42 @@ +#!/usr/bin/env python3 +""" +Simple test runner for ComfyUI-Manager tests. + +Usage: + python run_tests.py # Run all tests + python run_tests.py -k test_task_queue # Run specific tests + python run_tests.py --cov # Run with coverage +""" + +import sys +import subprocess +from pathlib import Path + +def main(): + """Run pytest with appropriate arguments""" + # Ensure we're in the project directory + project_root = Path(__file__).parent + + # Base pytest command + cmd = [sys.executable, "-m", "pytest"] + + # Add any command line arguments passed to this script + cmd.extend(sys.argv[1:]) + + # Add default arguments if none provided + if len(sys.argv) == 1: + cmd.extend([ + "tests/", + "-v", + "--tb=short" + ]) + + print(f"Running: {' '.join(cmd)}") + print(f"Working directory: {project_root}") + + # Run pytest + result = subprocess.run(cmd, cwd=project_root) + sys.exit(result.returncode) + +if __name__ == "__main__": + main() \ No newline at end of file diff --git a/tests/README.md b/tests/README.md new file mode 100644 index 00000000..dfbd5028 --- /dev/null +++ b/tests/README.md @@ -0,0 +1,89 @@ +# ComfyUI-Manager Tests + +This directory contains unit tests for ComfyUI-Manager components. + +## Running Tests + +### Using the Virtual Environment + +```bash +# From the project root +/path/to/comfyui/.venv/bin/python -m pytest tests/ -v +``` + +### Using the Test Runner + +```bash +# Run all tests +python run_tests.py + +# Run specific tests +python run_tests.py -k test_task_queue + +# Run with coverage +python run_tests.py --cov +``` + +## Test Structure + +### test_task_queue.py + +Comprehensive tests for the TaskQueue functionality including: + +- **Basic Operations**: Initialization, adding/removing tasks, state management +- **Batch Tracking**: Automatic batch creation, history saving, finalization +- **Thread Safety**: Concurrent access, worker lifecycle management +- **Integration Testing**: Full task processing workflow +- **Edge Cases**: Empty queues, invalid data, exception handling + +**Key Features Tested:** +- ✅ Task queueing with Pydantic model validation +- ✅ Batch history tracking and persistence +- ✅ Thread-safe concurrent operations +- ✅ Worker thread lifecycle management +- ✅ WebSocket message tracking +- ✅ State snapshots and transitions + +### MockTaskQueue + +The tests use a `MockTaskQueue` class that: +- Isolates testing from global state and external dependencies +- Provides dependency injection for mocking external services +- Maintains the same API as the real TaskQueue +- Supports both synchronous and asynchronous testing patterns + +## Test Categories + +- **Unit Tests**: Individual method testing with mocked dependencies +- **Integration Tests**: Full workflow testing with real threading +- **Concurrency Tests**: Multi-threaded access verification +- **Edge Case Tests**: Error conditions and boundary cases + +## Dependencies + +Tests require: +- `pytest` -
