"""
Comprehensive end-to-end integration tests for the openHAB MCP Server.

This module provides complete integration testing that covers:
1. All MCP server features and tools
2. Real openHAB instance integration (when available)
3. Docker deployment functionality
4. Complete workflows and error scenarios

Tests are designed to work with both mocked and real openHAB instances.
