-
-## Best Practices
-
-### Test Organization
-- **Unit tests**: Fast, isolated component testing
-- **Integration tests**: Component interaction testing
-- **GUI tests**: User interface and workflow testing
-- **Headless tests**: Logic testing without GUI dependencies
-
-### Performance Guidelines
-- **Unit tests**: <0.5s each
-- **Integration tests**: <2.0s each
-- **GUI tests**: <5.0s each (enforced by timeout)
-- **Total suite**: <120s with parallel execution
-
-### Coverage Targets
-- **Critical components**: >90% coverage
-- **Core functionality**: >80% coverage
-- **UI components**: >70% coverage
-- **Utility functions**: >60% coverage
-
-## Troubleshooting
-
-### Common Issues
-
-#### QApplication Conflicts
-```
-Error: QApplication RuntimeError
-Fix: Use class-level QApplication setup in GUI tests
-```
-
-#### Import Path Issues
-```
-Error: ModuleNotFoundError
-Fix: Use standardized src path setup:
-src_path = os.path.join(os.path.dirname(os.path.dirname(os.path.abspath(__file__))), 'src')
-sys.path.insert(0, src_path)
-```
-
-#### Test Timeouts
-```
-Error: Test timeout after 10s
-Fix: Optimize setup/teardown or use mocking for expensive operations
-```
-
-### Debug Commands
-```bash
-# Verbose test output
-python test_runner.py --verbose --no-parallel
-
-# Analyze specific failure pattern
-python test_analyzer.py --pattern timeout
-
-# Check test isolation
-python test_runner.py --workers 1 --repeat 5
-```
-
-## Migration from Existing Tests
-
-### Gradual Adoption
-1. **Install dependencies**: Add pytest and related packages
-2. **Run existing tests**: Use test_runner.py with current test files
-3. **Add markers**: Gradually add pytest markers for categorization
-4. **Enable parallel**: Test parallel execution with --no-parallel fallback
-5. **Integrate analysis**: Use test_analyzer.py for insights
-
-### Compatibility
-- **Existing test_*.py files**: Work unchanged with new infrastructure
-- **run_test_gui.bat**: Continues to work alongside new tools
-- **Test patterns**: Existing setUp/tearDown patterns are preserved
-- **Import styles**: Current import patterns are maintained
-
-## Integration with CI/CD
-
-### GitHub Actions Example
-```yaml
-- name: Run Tests with Analysis
- run: |
- python test_runner.py --parallel --format json --save results.json
- python test_analyzer.py --results results.json --format summary
-```
-
-### Quality Gates
-```bash
-# Fail build if health score too low
-python test_analyzer.py --format json | jq '.test_health_score < 70' && exit 1
-
-# Fail build if coverage drops
-python test_runner.py --coverage --format json | jq '.coverage.total < 80' && exit 1
-```
-
-## Future Enhancements
-
-### Planned Features
-- **Automatic test generation** from code changes
-- **Machine learning** for failure prediction
-- **Visual test reports** with interactive dashboards
-- **Integration** with external monitoring tools
-
-### Community Contributions
-- **Custom fix patterns** for domain-specific issues
-- **Additional test templates** for common PyFlowGraph patterns
-- **Performance optimizations** for large test suites
-- **Enhanced reporting formats** for different use cases

+### PySide6/Qt Testing Requirements
+**CRITICAL: DO NOT USE MOCK OBJECTS WITH QT COMPONENTS**
+
+Qt widgets and QGraphicsItems require actual Qt object instantiation and cannot be mocked:
+
+```python
+# ❌ FORBIDDEN - Causes Qt constructor errors
+def test_with_mock(self):
+ mock_group = Mock()
+ pin = GroupInterfacePin(mock_group, "test", "input", "any") # FAILS
+
+# ✅ CORRECT - Use real Qt objects or test fixtures
+def test_with_real_objects(self):
+ app = QApplication.instance() or QApplication([])
+ group = Group("TestGroup")
+ pin = GroupInterfacePin(group, "test", "input", "any") # WORKS
+```
+
+**Why Mock Fails with Qt:**
+- Qt constructors validate argument types at C++ level
+- Mock objects don't inherit from Qt base classes
+- QGraphicsItem requires proper parent/scene relationships
+
+**Alternative Testing Strategies:**
+- Use real Qt objects with minimal initialization
+- Create test fixture classes that inherit from actual Qt classes
+- Use dependency injection to isolate business logic from Qt dependencies
+- Test Qt-independent logic separately from Qt-dependent rendering

+# Commands Module
+
+This module implements the Command pattern for undo/redo functionality in PyFlowGraph. All user actions that modify the node graph are encapsulated as commands that can be executed, undone, and redone.
+
+## Purpose
+
+The commands module provides a robust undo/redo system by implementing the Command design pattern. Each user action (creating nodes, making connections, moving objects) is wrapped in a command object that knows how to execute itself and how to reverse its effects.
+
+## Key Files
+
+### `__init__.py`
+Standard Python package initialization file.
+
+### `command_base.py`
+- **CommandBase**: Abstract base class defining the command interface
+- **CompositeCommand**: Container for grouping multiple commands into a single undoable action
+- Provides the foundation for all command implementations
+
+### `command_history.py`
+- Manages the undo/redo stack
+- Tracks command execution history
+- Handles command grouping and batch operations
+- Provides undo/redo state management
+
+### `connection_commands.py`
+Commands related to connection operations:
+- Creating connections between pins
+- Deleting connections
+- Rerouting connections through reroute nodes
+- Connection validation and error handling
+
+### `create_group_command.py`
+Commands for group management:
+- Creating node groups from selected nodes
+- Managing group boundaries and interfaces
+- Group creation validation and setup
+
+### `node_commands.py`
+Commands for node operations:
+- Creating new nodes
+- Deleting nodes
+- Moving nodes
+- Modifying node properties
+- Node position and state management
+
+### `resize_group_command.py`
+Commands specific to group resizing:
+- Resizing group boundaries
+- Maintaining group interface consistency
+- Validating group size constraints
+
+## Dependencies
+
+- **Core Module**: Commands operate on core objects (nodes, pins, connections, groups)
+- **Event System**: Commands may trigger events for UI updates
+- **Node Graph**: Commands modify the main graph scene
+
+## Usage Notes
+
+- All commands inherit from `CommandBase` and implement `execute()` and `undo()` methods
+- Commands are automatically added to the command history when executed
+- Composite commands allow grouping related operations for single undo/redo
+- Commands handle their own validation and error states
+- The command system supports both immediate execution and deferred execution patterns
+
+## Architecture Integration
+
+The command system is central to PyFlowGraph's user interaction model, ensuring that all graph modifications can be undone and redone reliably. This provides a professional editing experience and prevents data loss from user mistakes.

+### `group_interface_pin.py`
+- **GroupInterfacePin**: Special pins that represent group inputs/outputs
+- Automatic generation based on internal connections
+- Type inference from grouped node pins
+- Interface consistency and validation
+
+### `group_pin_generator.py`
+- Analyzes node groups to generate appropriate interface pins
+- Determines required inputs and outputs for groups
+- Manages pin type consistency across group boundaries
+- Handles complex group interface scenarios
+
+### `group_type_inference.py`
+- Infers data types for group interface pins
+- Analyzes internal node connections for type propagation
+- Handles type conflicts and resolution
+- Provides type validation for group interfaces
+
+### `connection_analyzer.py`
+- Analyzes connection validity and data flow
+- Detects circular dependencies and invalid connections
+- Provides connection suggestions and error reporting
+- Optimizes connection routing and performance
+
+### `event_system.py`
+- **EventSystem**: Centralized event handling for the node graph
+- Live mode execution support
+- Event propagation and listener management
+- Integration with execution engine for real-time updates
+
+## Dependencies
+
+- **Qt Framework**: Uses QGraphicsScene, QGraphicsItem for rendering
+- **Data Module**: For serialization and file format handling
+- **Execution Module**: For node execution and data flow
+- **Commands Module**: For undo/redo operations
+
+## Usage Notes
+
+- All core objects are designed to work within Qt's graphics framework
+- Node pins are automatically generated from Python function signatures
+- The event system enables real-time execution and live mode
+- Groups provide hierarchical organization without affecting execution logic
+- Connection validation ensures type safety and prevents invalid data flow
+
+## Architecture Integration
+
+The core module is the foundation of PyFlowGraph's visual scripting capabilities. It bridges the gap between Python code and visual representation, enabling intuitive node-based programming while maintaining the full power of Python.

+# Data Module
+
+This module handles data persistence, file operations, and format conversions for PyFlowGraph. It manages the serialization and deserialization of node graphs, providing clean and efficient file formats for saving and loading projects.
+
+## Purpose
+
+The data module abstracts all file operations and data format handling, ensuring consistent and reliable persistence of node graphs. It supports multiple file formats and provides robust error handling for file operations.
+
+## Key Files
+
+### `__init__.py`
+Standard Python package initialization file.
+
+### `file_operations.py`
+- Core file I/O operations for node graphs
+- File loading and saving with error handling
+- Import/export functionality for different formats
+- File validation and integrity checking
+- Backup and recovery mechanisms
+- Recent files management
+
+### `flow_format.py`
+- **FlowFormat**: Implementation of PyFlowGraph's native markdown-based format
+- JSON-based graph serialization and deserialization
+- Node graph structure preservation
+- Metadata handling and versioning
+- Format conversion utilities
+- Backward compatibility support
+
+## File Format Details
+
+### Markdown Flow Format (.md)
+PyFlowGraph uses a clean markdown-based format that combines:
+- Human-readable project information
+- JSON serialization of the complete node graph
+- Embedded metadata for versioning and compatibility
+- Comments and documentation support
+
+### JSON Structure
+The serialized graph includes:
+- Node definitions with code and properties
+- Pin configurations and type information
+- Connection mappings between nodes
+- Group structures and hierarchies
+- View state and layout information
+
+## Dependencies
+
+- **Core Module**: Serializes core objects (nodes, pins, connections, groups)
+- **JSON**: Standard library for data serialization
+- **File System**: Platform-specific file operations
+- **Error Handling**: Robust error reporting and recovery
+
+## Usage Notes
+
+- All file operations include comprehensive error handling
+- The markdown format is designed to be both machine and human readable
+- JSON serialization preserves complete graph state including visual layout
+- File format versioning ensures backward compatibility
+- Large graphs are efficiently serialized with minimal memory usage
+
+## Format Examples
+
+### Basic Flow File Structure
+```markdown
+# Project Title
+
+Project description and documentation.
+
+## Graph Data

+# Execution Module
+
+This module provides the graph execution engine that runs PyFlowGraph node networks. It implements data-driven execution with subprocess isolation, ensuring secure and reliable code execution while maintaining performance and stability.
+
+## Purpose
+
+The execution module transforms visual node graphs into executable programs. It handles data flow analysis, dependency resolution, subprocess management, and provides both batch and interactive execution modes for different use cases.
+
+## Key Files
+
+### `__init__.py`
+Standard Python package initialization file.
+
+### `graph_executor.py`
+- **GraphExecutor**: Main execution engine for node graphs
+- Data-driven execution with automatic dependency resolution
+- Subprocess isolation for security and stability
+- JSON-based data serialization between processes
+- Error handling and execution state management
+- Performance optimization and caching
+
+### `execution_controller.py`
+- **ExecutionController**: Central coordination for graph execution
+- Execution mode management (batch, interactive, live)
+- Progress tracking and status reporting
+- Resource management and cleanup
+- Integration with UI for execution feedback
+
+### `environment_manager.py`
+- **EnvironmentManager**: Abstract base class for Python environment management
+- Virtual environment detection and selection
+- Package installation and dependency management
+- Environment isolation and configuration
+- Cross-platform environment handling
+
+### `default_environment_manager.py`
+- **DefaultEnvironmentManager**: Default implementation of environment management
+- System Python environment detection
+- Basic virtual environment support
+- Fallback environment configuration
+- Simple dependency resolution
+
+## Execution Process
+
+### Data Flow Execution
+1. **Dependency Analysis**: Determines execution order based on data dependencies
+2. **Node Preparation**: Serializes node code and input data
+3. **Subprocess Launch**: Executes nodes in isolated Python processes
+4. **Data Transfer**: Passes results between nodes via JSON serialization
+5. **Result Collection**: Aggregates outputs and handles errors
+
+### Security Features
+- **Process Isolation**: Each node runs in a separate subprocess
+- **Sandboxing**: Limited access to system resources
+- **Timeout Management**: Prevents infinite loops and hanging processes
+- **Resource Limits**: Memory and CPU usage constraints
+- **Code Validation**: Basic safety checks before execution
+
+## Dependencies
+
+- **Core Module**: Executes core node objects and manages data flow
+- **Subprocess**: Python standard library for process management
+- **JSON**: Data serialization for inter-process communication
+- **Event System**: Progress reporting and status updates
+
+## Usage Notes
+
+- All node execution happens in isolated subprocesses for security
+- Data flow is JSON-serializable, limiting supported data types
+- Execution order is determined automatically from node connections
+- Long-running nodes can be cancelled and provide progress updates
+- Virtual environment support allows using different Python setups
+
+## Execution Modes
+
+### Batch Mode
+- Executes entire graph from start to finish
+- Optimized for performance and resource usage
+- Suitable for data processing pipelines
+- Provides comprehensive error reporting
+
+### Interactive Mode
+- Executes individual nodes or subgraphs
+- Real-time feedback and debugging support
+- Allows incremental development and testing
+- Integrates with live mode for immediate updates
+
+### Live Mode
+- Automatically re-executes when inputs change
+- Real-time data visualization and monitoring
+- Suitable for interactive applications and dashboards
+- Event-driven execution with minimal latency
+
+## Architecture Integration
+
+The execution module is the runtime engine that brings PyFlowGraph's visual programs to life. It bridges the gap between visual design and actual computation, providing a secure and efficient platform for running complex data processing workflows.

+# Resources Module
+
+This module contains embedded resources used by PyFlowGraph's user interface, primarily Font Awesome font files that provide scalable vector icons throughout the application.
+
+## Purpose
+
+The resources module centralizes all static assets required by the application, ensuring that PyFlowGraph can display professional-quality icons and graphics without external dependencies. All resources are embedded directly in the application for reliable distribution.
+
+## Key Files
+
+### Font Awesome Font Files
+
+#### `Font Awesome 6 Free-Solid-900.otf`
+- **Font Awesome 6 Solid**: Solid style icons from Font Awesome 6
+- Contains filled, bold icons for primary UI elements
+- Used for main toolbar buttons, menu icons, and prominent interface elements
+- Provides consistent visual language across the application
+
+#### `Font Awesome 7 Free-Regular-400.otf`
+- **Font Awesome 7 Regular**: Regular style icons from Font Awesome 7
+- Contains outlined icons for secondary UI elements
+- Used for status indicators, optional features, and subtle interface elements
+- Complements the solid icons with lighter visual weight
+
+## Font Integration
+
+### Loading Process
+The fonts are loaded at application startup in `main.py`:
+1. Font files are detected in the resources directory
+2. Fonts are registered with the Qt font database
+3. Font families become available for use throughout the application
+
+### Usage in UI
+- **Icon Rendering**: Fonts are used to render scalable vector icons
+- **Consistent Styling**: Provides uniform icon appearance across different screen DPI settings
+- **Performance**: Vector icons scale efficiently without pixelation
+- **Customization**: Icons can be styled with CSS and Qt stylesheets
+
+## Dependencies
+
+- **Qt Font System**: Uses Qt's QFontDatabase for font registration
+- **Main Application**: Loaded during application initialization
+- **UI Components**: Used throughout the interface for icon display
+
+## Usage Notes
+
+- Font files are embedded as application resources
+- Icons are rendered as text characters using specific Unicode points
+- Font Awesome provides thousands of professional icons
+- Icons automatically scale with system font size and DPI settings
+- Both solid and regular styles provide visual hierarchy options
+
+## Icon Categories
+
+### Available Icon Types
+- **File Operations**: Open, save, import, export icons
+- **Edit Actions**: Cut, copy, paste, undo, redo icons
+- **Node Operations**: Add, delete, connect, group icons
+- **View Controls**: Zoom, pan, fullscreen, layout icons
+- **Execution**: Play, stop, pause, debug icons
+- **Settings**: Configuration, preferences, options icons
+
+## Architecture Integration
+
+The resources module ensures PyFlowGraph has a professional, consistent visual appearance. By embedding Font Awesome fonts, the application provides scalable, high-quality icons that work reliably across different platforms and display configurations without requiring external font installations.

-# Final Test Summary - GUI Loading Bug Investigation
-
-## Issue Report
-**Original Problem**: "Any node that has a GUI doesn't load correctly" from `text_processing_pipeline.md`
-
-## Investigation Results
-
-After comprehensive testing, I discovered that the issue is **NOT** a GUI rendering problem, but a **pin categorization bug**.
-
-### ✅ What Works Correctly
-
-1. **GUI Components ARE Loading**: All GUI nodes show:
- - Widgets created properly (3-4 widgets per node)
- - Proxy widgets visible and correctly sized
- - GUI code executing without errors
- - GUI state being applied correctly
-
-2. **Examples from text_processing_pipeline.md**:
- - "Text Input Source": 3 widgets, 276×317px, visible ✅
- - "Text Cleaner & Normalizer": 4 widgets, 250×123px, visible ✅
- - "Keyword & Phrase Extractor": 2 widgets, 250×96px, visible ✅
- - "Processing Report Generator": 3 widgets, 276×313px, visible ✅
-
-### ❌ The Real Bug: Pin Direction Categorization
-
-**Root Cause**: Nodes loaded from markdown have pins, but the pins lack proper `pin_direction` attributes.
-
-**Evidence**:
-- Node shows "Total pins: 9" ✅
-- But "Input pins: 0" and "Output pins: 0" ❌
-- Pin direction filtering `[p for p in pins if p.pin_direction == 'input']` returns empty arrays
-
-**This explains the reported symptoms**:
-1. **"GUI doesn't show"** → Actually, connections don't work because pins aren't categorized properly
-2. **"Pins stuck in top-left"** → Pin positioning fails when pin_direction is undefined
-3. **"Zero height nodes"** → Layout calculations fail without proper pin categorization
-
-### Test Files Created
-
-1. **`test_gui_loading_bugs.py`** - Basic GUI loading tests (7 tests)
-2. **`test_gui_rendering.py`** - Visual rendering verification (5 tests)
-3. **`test_specific_gui_bugs.py`** - Targeted bug reproduction (3 tests)
-4. **`test_pin_creation_bug.py`** - Root cause identification (3 tests)
-
-### Recommended Fix
-
-The issue is in the pin creation/categorization during markdown deserialization. Need to investigate:
-
-1. **`node.py`** - `update_pins_from_code()` method
-2. **`pin.py`** - Pin direction assignment during creation
-3. **`node_graph.py`** - Pin handling during `deserialize()`
-
-The pin direction attributes (`pin_direction = "input"/"output"`) are not being set correctly when nodes are loaded from markdown format.
-
-### Test Commands
-
-To reproduce the bug:
-```bash
-python test_pin_creation_bug.py
-```
-
-To verify GUI components work correctly:
-```bash
-python test_gui_rendering.py
-```
-
-## Conclusion
-
-The "GUI loading bug" is actually a **pin categorization bug** that makes the nodes appear broken because connections don't work properly. The GUI components themselves are loading and rendering correctly.
-
-**Next Steps**: Fix the pin direction assignment during markdown deserialization process.

-# GUI Loading Tests for PyFlowGraph
-
-This document describes the unit tests created to detect GUI-related loading issues in markdown graphs.
-
-## Problem Statement
-
-The issue reported was: "any node that has a GUI doesn't load correctly" when loading markdown graphs. This suggests systematic problems with GUI component initialization during the markdown-to-graph deserialization process.
-
-## Test Files Created
-
-### 1. `test_gui_loading_bugs.py` - Core Bug Detection Tests
-
-This is the main test file focused specifically on GUI loading issues. It contains targeted tests for:
-
-- **Basic GUI Loading**: Verifies that nodes with GUI components load and rebuild successfully
-- **Zero Height Bug**: Tests for the specific bug mentioned in git commits where nodes had zero height after loading
-- **GUI Code Execution Errors**: Ensures that syntax errors in GUI code are handled gracefully
-- **Proxy Widget Creation**: Verifies that QGraphicsProxyWidget objects are properly created for GUI nodes
-- **GUI State Handling**: Tests that saved GUI state is properly applied during loading
-- **Reroute Node Loading**: Ensures reroute nodes don't cause GUI-related errors
-- **Real File Loading**: Tests loading actual markdown example files
-
-### 2. `test_gui_loading.py` - Comprehensive Test Suite
-
-This is a more extensive test suite that includes:
-
-- Complex GUI layout testing
-- Malformed JSON handling
-- Missing GUI state handlers
-- FileOperations integration testing
-- GUI refresh mechanisms
-
-## Key Testing Areas
-
-### GUI Component Lifecycle
-
-1. **Loading Phase**: Markdown → JSON → Node deserialization
-2. **GUI Rebuild Phase**: Executing `gui_code` to create Qt widgets
-3. **State Application Phase**: Applying saved `gui_state` to widgets
-4. **Rendering Phase**: QGraphicsProxyWidget integration
-
-### Common Failure Points Tested
-
-1. **Syntax Errors in GUI Code**: Invalid Python code in GUI Definition sections
-2. **Missing Dependencies**: Qt widgets not properly imported
-3. **Widget Creation Failures**: Errors during widget instantiation
-4. **State Application Errors**: GUI state not matching widget structure
-5. **Height/Sizing Issues**: Nodes with zero or negative dimensions
-6. **Proxy Widget Failures**: QGraphicsProxyWidget not created properly
-
-### Error Handling Verification
-
-The tests verify that:
-- Invalid GUI code doesn't crash the application
-- Missing GUI components are handled gracefully
-- Malformed metadata doesn't prevent loading
-- Error nodes still maintain basic functionality
-
-## Running the Tests
-
-### Quick GUI Bug Detection
-```bash
-python test_gui_loading_bugs.py
-```
-
-### Comprehensive GUI Testing
-```bash
-python test_gui_loading.py
-```
-
-### Test Output Interpretation
-
-- **All tests pass**: No GUI loading bugs detected
-- **Test failures**: Specific GUI loading issues identified
-- **Error output**: Details about what failed and where
-
-## Test Strategy
-
-### Unit Test Approach
-- Each test focuses on a specific aspect of GUI loading
-- Tests use synthetic markdown content to isolate issues
-- Real file testing validates against actual usage
-
-### Synthetic Test Data
-- Minimal markdown content that exercises specific features
-- Controlled scenarios for reproducing bugs
-- Known-good and known-bad test cases
-
-### Error Simulation
-- Deliberately malformed GUI code
-- Missing required components
-- Invalid metadata structures
-
-## Integration with Development Workflow
-
-### Pre-commit Testing
-Add to git hooks or CI/CD pipeline:
-```bash
-python test_gui_loading_bugs.py && echo "GUI loading tests passed"
-```
-
-### Regression Testing
-Run these tests whenever:
-- GUI-related code is modified
-- Markdown loading logic is changed
-- Node serialization/deserialization is updated
-- Qt widget handling is modified
-
-### Bug Reproduction
-When GUI loading issues are reported:
-1. Create a test case that reproduces the issue
-2. Fix the underlying problem
-3. Verify the test now passes
-4. Add the test to the suite permanently
-
-## Future Enhancements
-
-### Additional Test Coverage
-- Performance testing for large graphs with many GUI nodes
-- Memory leak detection during repeated load/unload cycles
-- Cross-platform GUI rendering differences
-- Complex widget interaction testing
-
-### Automated Testing
-- Integration with CI/CD systems
-- Automated testing of example files
-- Performance benchmarking
-- Visual regression testing
-
-## Maintenance
-
-### Updating Tests
-When new GUI features are added:
-1. Add corresponding test cases
-2. Update test documentation
-3. Verify backwards compatibility
-
-### Test Data Maintenance
-- Keep synthetic test markdown in sync with format changes
-- Update expected behaviors when GUI system evolves
-- Maintain test examples that cover edge cases
-
-## Conclusion
-
-These test suites provide comprehensive coverage for GUI loading issues in PyFlowGraph's markdown format. They serve as both regression prevention and debugging tools, helping maintain reliable GUI functionality as the codebase evolves.
