Connection creation by dragging between ports + - Connection disconnection by dragging from ports and deletion of selected connections + - Zoom and pan operations with mouse wheel and drag + - Keyboard shortcuts (delete key, Ctrl+Z undo) + - Context menu interactions (right-click) + - Stress testing with rapid mouse movements and memory load + - Virtual display testing with proper window exposure handling + +Key Features +------------ + +**Segfault Resolution**: Fixed critical infinite recursion in signal emission +that was causing stack overflow crashes during graphics system updates. + +**API Modernization**: Updated from v2.x to v3.x Model-View architecture +with proper AbstractGraphModel implementation following QtNodes best practices. + +**Clean Dependencies**: Removed internal header dependencies, using only +public APIs for better stability and maintainability. + +**Signal Emission Testing**: Comprehensive verification of all AbstractGraphModel +signals using QSignalSpy, ensuring proper signal emission for all operations +including node creation/deletion, connection creation/deletion, and node updates. + +**Comprehensive Coverage**: Tests all major functionality including node +management, connections, serialization, undo system, and graphics integration. + +**Port Bounds Validation**: Added proper validation in ``connectionPossible()`` +to ensure port indices are within valid ranges. + +Building Tests +-------------- + +Tests are built automatically when ``BUILD_TESTING`` is enabled (default). + +**Prerequisites:** + - Catch2 testing framework + - Qt6 (or Qt5 with appropriate configuration) + - CMake 3.8+ + +**Configuration:** + +.. code-block:: bash + + # Enable testing (default) + cmake .. -DBUILD_TESTING=ON + + # Disable testing + cmake .. -DBUILD_TESTING=OFF + +**Build:** + +.. code-block:: bash + + # Build library and tests + make + + # Build only tests + make test_nodes + +Test Implementation Details +--------------------------- + +**TestGraphModel**: A complete implementation of ``AbstractGraphModel`` that provides: + - Full node and connection management + - Proper signal emission patterns + - Serialization support + - Integration with graphics systems + +**UITestHelper**: A namespace providing utility functions for UI interaction testing: + - ``simulateMousePress/Move/Release()`` - Low-level mouse event simulation + - ``simulateMouseDrag()`` - High-level drag operation simulation + - ``waitForUI(ms = 10)`` - Optimized UI event processing with 10ms default timing + - Proper Qt event system integration for realistic UI testing + +**Signal Safety**: The test model implements signal emission patterns that prevent +infinite recursion between the model and graphics system, following the approach +used in ``examples/simple_graph_model``. + +**Mock Objects**: Comprehensive stub implementations for testing without external +dependencies, including ``StubNodeDataModel`` for node delegate testing. + +Troubleshooting +--------------- + +**Common Issues:** + +* **Catch2 not found**: Install Catch2 or disable testing with ``-DBUILD_TESTING=OFF`` +* **Qt version conflicts**: Ensure consistent Qt5/Qt6 usage throughout build +* **Missing test binary**: Check that ``BUILD_TESTING`` is enabled in CMake configuration + +**Performance Notes:** + - Tests include Qt application setup overhead + - Graphics tests may show Qt warnings about runtime directories (these are harmless) + - UI tests use optimized 10ms timing for consistent performance + -
