Test Harness Features

• Message composition and sending
• State visualization
• Event logging
• Interactive geometry manipulation
• Real-time state updates

Implementation Requirements

1. XAML Controls

   • Message input panel
   • State visualization
   • Event log viewer
   • Geometry container

2. ViewModels

   • Message handling
   • State management
   • Event routing visualization

3. Testing

   • Unit tests for geometry behaviors
   • Integration tests for MQTT scenarios
   • Visual state verification

Getting Started

1. Add the test harness to your project:

<Window ...>
    <controls:GeometryTestHarness
        GeometryType="Tree"
        InitialState="{Binding State}"
        MessageHandler="{Binding HandleMessage}" />
</Window>

2. Configure your ViewModel:

public class MainViewModel : INotifyPropertyChanged
{
    public GeometryState State { get; }
    public ICommand HandleMessage { get; }
    
    // Implementation details...
}

3. Run and test:
   • Enter test messages
   • Observe state changes
   • View event routing
   • Verify MQTT processing
