   • Security scanning (optional)

3. 🔗 INTEGRATION

   • Simple E2E tests (required)

   • Comprehensive E2E tests (manual)

   • Static NPC verification

   • Combat system verification

   • Enemy spawning verification

4. 🚀 DEPLOY

   • Staging deployment (manual)

   • Production deployment (manual)

Pipeline Jobs

Required Jobs (Blocking)

✅ build - Server compilation ✅ unit_tests - Unit test execution ✅ e2e_simple - Core functionality tests ✅ static_npc_verification - NPC system tests ✅ combat_system_verification - Combat tests ✅ enemy_spawning_verification - Spawning tests

Optional Jobs (Non-blocking)

⚠️ code_quality - Code formatting and style ⚠️ security_scan - Security vulnerability scan ⚠️ e2e_comprehensive - Advanced feature tests

Manual Jobs

🔧 deploy_staging - Staging environment deployment 🔧 security_scan - Manual security analysis

📊 Test Coverage

✅ Comprehensive Test Suite

• Unit Tests: All packages (lib, config, routines)

• Simple E2E Tests: Core server functionality

• Comprehensive E2E Tests: Advanced game features

• System Verification: Specific system components

🎯 Key Areas Tested

• Server connection and RLogin protocol

• Static NPC spawning (Oria, Hanrod, Wenzel, etc.)

• Enemy spawning system with tick timing

• Combat system components

• Multiple client connections

• Server stability and performance

• Player creation and authentication

• Game commands and interactions

🛠️ Local Development Workflow

Quick Validation

# Validate entire CI pipeline locally
./dev_tools/validate-ci-pipeline.sh

Individual Components

# Setup CI environment
./scripts/ci-setup.sh

# Run simple E2E tests
./run_simple_e2e.sh

# Generate test reports
./scripts/generate-test-reports.sh

Pre-commit Checks

# Format code
gofmt -w .

# Run unit tests
go test ./lib/... ./config/... ./routines/...

# Build server
go build -o openroads .
