"""Integration tests for FreeCAD MCP GUI mode.

These tests verify that the MCP bridge works correctly when FreeCAD is running
in GUI mode (with full graphical interface). They test GUI-specific features
like visibility, display modes, colors, and camera operations.

Note: These tests require a running FreeCAD GUI server.
      Start it with: just run-gui

To run these tests:
