Agent E9: API Endpoint Integration Tests - Quick Reference

Status: ✅ COMPLETE Date: 2025-10-18 Agent: E9 (Wave D - Phase 4)

---

Quick Start

1. Automated Testing (Recommended)

# Run complete integration test suite
./scripts/test_regime_endpoints.sh

2. Manual Testing

Start Services

docker-compose up -d
cargo run -p trading_service --bin trading_service --release &
cargo run -p api_gateway --release &
sleep 5

Test with grpcurl

# GetRegimeState (direct to Trading Service)
grpcurl -plaintext \
  -d '{"symbol":"ES.FUT"}' \
  localhost:50052 \
  foxhunt.trading.TradingService/GetRegimeState

# GetRegimeTransitions
grpcurl -plaintext \
  -d '{"symbol":"ES.FUT","limit":10}' \
  localhost:50052 \
  foxhunt.trading.TradingService/GetRegimeTransitions

# Via API Gateway (port 50051)
grpcurl -plaintext \
  -d '{"symbol":"NQ.FUT"}' \
  localhost:50051 \
  foxhunt.trading.TradingService/GetRegimeState

Test with TLI

# Login first
tli auth login

# View current regime
tli trade ml regime --symbol ES.FUT

# View transitions
tli trade ml transitions --symbol ES.FUT --limit 20

Run Integration Tests

# Run all tests (requires services running)
cargo test -p trading_service --test regime_grpc_integration_test -- --ignored

# Run specific test
cargo test -p trading_service --test regime_grpc_integration_test \
  test_get_regime_state_es_fut -- --ignored --nocapture

# Run performance tests
cargo test -p trading_service --test regime_grpc_integration_test \
  test_regime_state_performance -- --ignored --nocapture

Test Coverage

GetRegimeState (3 tests)

• ✅ test_get_regime_state_es_fut: ES.FUT regime state
• ✅ test_get_regime_state_nq_fut: NQ.FUT regime state
• ✅ test_get_regime_state_invalid_symbol: Error handling

GetRegimeTransitions (3 tests)

• ✅ test_get_regime_transitions_es_fut: Basic transitions (limit=10)
• ✅ test_get_regime_transitions_large_limit: Large limit (limit=100)
• ✅ test_get_regime_transitions_multiple_symbols: Multi-symbol validation

Performance (2 tests)

• ✅ test_regime_state_performance: P99 < 10ms (100 requests)
• ✅ test_regime_transitions_performance: P99 < 50ms (50 requests, limit=100)

Concurrent Access (1 test)

• ✅ test_concurrent_regime_state_requests: 10 parallel requests

Total: 9 integration tests

Performance Targets

Endpoint	Target	Test
GetRegimeState	P99 < 10ms	test_regime_state_performance
GetRegimeTransitions (limit=100)	P99 < 50ms	test_regime_transitions_performance

TLI Commands

View Current Regime

tli trade ml regime --symbol ES.FUT

Output:

📊 Regime State: ES.FUT
  Regime: TRENDING
  Confidence: 87.00%
  Time in Regime: 1234.56s

View Regime Transitions

tli trade ml transitions --symbol ES.FUT --limit 20

Output:

📈 Regime Transitions: ES.FUT

  1. RANGING → TRENDING (2025-10-18 07:30:00)
     Confidence: 91.00%

  2. VOLATILE → RANGING (2025-10-18 06:45:00)
     Confidence: 85.00%

Troubleshooting

Services Not Starting

# Check port availability
lsof -i :50052  # Trading Service
lsof -i :50051  # API Gateway

# Kill existing processes
pkill -f trading_service
pkill -f api_gateway

# Restart
./scripts/test_regime_endpoints.sh

Integration Tests Fail

# Check if services are running
curl http://localhost:8081/health  # Trading Service
curl http://localhost:8080/health  # API Gateway

# Check logs
tail -f /tmp/trading_service.log
tail -f /tmp/api_gateway.log

TLI Authentication Fails

# Re-login
tli auth login

# Check token
tli auth status

Next Steps

1. Agent E10: Performance Benchmarking

   • Run performance tests with real data
   • Validate P99 latency targets
   • Document performance metrics

2. Agent E11: End-to-End Validation

   • Full TLI → API Gateway → Trading Service flow
   • Multi-symbol concurrent testing
   • Load testing (100+ concurrent requests)

3. Agent E12: Wave D Phase 4 Completion

   • Integration summary
   • Production readiness checklist
   • Wave D completion report
