Add comprehensive test structure for all engines
🧪 Created complete API testing architecture:
- Organized tests/ directory with folder per engine
- Google Test framework setup for each engine
- API validation tests for all 10 autonomous engines
✅ Test coverage includes:
- Factory Engine: Production API, 60fps performance, material flow
- War Engine: Multi-chunk combat, auto-battler, 500 units capacity
- Designer Engine: Global 1-2 designs/tick rate, design evolution
- Map Engine: 218 procedural elements, FOW chunk granularity
- Intelligence Engine: 3.1GB adaptive metrics, satellite reconnaissance
- MacroEntity Engine: Company features, diplomacy, admin points
- Operation Engine: AI generals, ML adaptation, strategic planning
- Logistic Engine: Supply chains, convoy management, route optimization
- Economy Engine: Market simulation, pricing, geopolitical events
- Event Engine: Breakthrough system, global events, scheduling
🎯 Each test validates:
- Engine API correctness and functionality
- Performance targets and specifications
- Inter-engine communication patterns
- Technical requirements from documentation
📋 Added helpers/ directory for build utilities and tools
🚀 Ready for TDD implementation and continuous validation
