Agent T15: E2E Integration Test Status Report

Date: 2025-10-18 Agent: T15 (E2E Integration Test Check) Mission: Assess E2E test status and identify blocking issues Status: ⚠️ BLOCKERS IDENTIFIED (3 categories, ~2 hours to fix)

---

🎯 Executive Summary

Current E2E Test Status: 20/20 library tests passing, but 0/28 integration tests running due to compilation blockers.

Root Cause: Three categories of issues blocking E2E test execution:

1. SQLx Offline Mode (6 queries missing cache) - 60 min fix
2. Schema Mismatch (DQN hyperparameters) - 30 min fix
3. Test Infrastructure (service orchestration) - 30 min fix

Good News:

• ✅ Proto schemas are UP TO DATE with Wave D regime methods
• ✅ Framework library tests: 20/20 passing (100%)
• ✅ No critical architectural issues found
• ✅ Agent I1 fixes from Wave D Phase 6 are applied

Estimated Fix Time: 2.0 hours (vs. 2 hours estimate in CLAUDE.md)

🔍 Issue Analysis

Issue #1: SQLx Offline Mode Cache Missing (Priority: HIGH)

Impact: 3 test files blocked (26 errors total) Estimated Fix: 60 minutes

Root Cause: SQLX_OFFLINE=true environment variable is set, but no cached query metadata exists for E2E tests.

Affected Files:

tests/e2e/tests/e2e_ml_training_test.rs     (20 errors)
tests/e2e/tests/e2e_ml_paper_trading_test.rs (4 errors)
tests/e2e/tests/e2e_ml_backtesting_test.rs   (2 errors)

Missing Queries (6 total):

1. INSERT INTO ml_predictions (symbol, model_name, predicted_action, ...)
2. UPDATE ml_predictions SET actual_action = predicted_action WHERE order_id = $1
3. SELECT id, predicted_action, confidence, symbol FROM ml_predictions WHERE order_id = $1
4. SELECT pnl, outcome_recorded_at FROM ml_predictions WHERE order_id = $1
5. INSERT INTO backtest_runs (id, strategy, symbol, start_date, ...)
6. SELECT id, strategy, symbol, total_trades FROM backtest_runs WHERE id = $1

Fix Strategy:

# Option 1: Generate SQLx cache (recommended)
cd /home/jgrusewski/Work/foxhunt/tests/e2e
cargo sqlx prepare --database-url postgresql://foxhunt:foxhunt_dev_password@localhost:5432/foxhunt

# Option 2: Disable offline mode for E2E tests (faster, less safe)
# In tests/e2e/Cargo.toml:
[features]
default = []
offline = ["sqlx/offline"]

# Then build without offline feature:
cargo test -p foxhunt_e2e --no-default-features

Recommendation: Use Option 1 (generate cache) for production readiness.

Issue #2: DQN Hyperparameters Schema Mismatch (Priority: MEDIUM)

Impact: 1 test file blocked (1 error) Estimated Fix: 30 minutes

Root Cause: Test code uses old DQNHyperparameters struct without new early stopping fields added in Wave D.

Affected File:

tests/e2e/tests/dqn_training_test.rs:48

Error:

error[E0063]: missing fields `early_stopping_enabled`, `min_epochs_before_stopping`,
              `min_loss_improvement_pct` and 2 other fields in initializer of `DQNHyperparameters`
  --> tests/e2e/tests/dqn_training_test.rs:48:23

Missing Fields (5 total):

pub struct DQNHyperparameters {
    // ... existing fields ...
    pub early_stopping_enabled: bool,         // NEW (Wave D)
    pub q_value_floor: f64,                   // NEW (Wave D)
    pub min_loss_improvement_pct: f64,        // NEW (Wave D)
    pub plateau_window: usize,                // NEW (Wave D)
    pub min_epochs_before_stopping: usize,    // NEW (Wave D)
}

Fix:

// In tests/e2e/tests/dqn_training_test.rs:48
let hyperparams = DQNHyperparameters {
    learning_rate: 0.001,
    batch_size: 64,
    gamma: 0.99,
    epsilon_start: 1.0,
    epsilon_end: 0.01,
    epsilon_decay: 0.995,
    buffer_size: 10_000,
    epochs: 5,
    checkpoint_frequency: 2,
    // NEW: Add early stopping configuration
    early_stopping_enabled: false,           // Disable for short test
    q_value_floor: 0.5,                      // Default threshold
    min_loss_improvement_pct: 2.0,           // 2% improvement required
    plateau_window: 30,                      // 30 epoch window
    min_epochs_before_stopping: 50,          // Minimum 50 epochs
};

---

Issue #3: Test Infrastructure & Service Orchestration (Priority: LOW)

Impact: Unknown number of runtime failures Estimated Fix: 30 minutes

Potential Issues:

1. Service Port Conflicts: Tests expect services on ports 50051-50055
2. JWT Secret Configuration: Tests require JWT_SECRET environment variable
3. Database Connectivity: Tests need PostgreSQL at localhost:5432
4. Test Data Availability: Some tests require DBN files in test_data/real/databento/

Pre-Flight Checklist:

# 1. Check Docker services
docker-compose ps | grep -E "(postgres|redis)"

# 2. Check service ports
lsof -i :50051,50052,50053,50054,50055 || echo "Ports available"

# 3. Check JWT secret
grep JWT_SECRET .env || echo "JWT_SECRET=<generate-with-openssl-rand-base64-64>" >> .env

# 4. Check database
psql postgresql://foxhunt:foxhunt_dev_password@localhost:5432/foxhunt -c "SELECT version();"

# 5. Check test data
ls -lh test_data/real/databento/ml_training_small/*.dbn.zst 2>/dev/null | wc -l

✅ Positive Findings

1. Proto Schema Validation

Status: ✅ UP TO DATE

The E2E proto files include all Wave D Phase 6 additions:

// /home/jgrusewski/Work/foxhunt/tests/e2e/src/proto/trading.rs
service TradingService {
    // ... existing methods ...
    rpc GetRegimeState(GetRegimeStateRequest) returns (GetRegimeStateResponse);
    rpc GetRegimeTransitions(GetRegimeTransitionsRequest) returns (GetRegimeTransitionsResponse);
}

// Both trading_service proto and TLI proto have these methods:
- trading.TradingService/GetRegimeState
- foxhunt.tli.TradingService/GetRegimeState
- trading.TradingService/GetRegimeTransitions
- foxhunt.tli.TradingService/GetRegimeTransitions

Verification:

$ grep -r "GetRegimeState\|GetRegimeTransitions" tests/e2e/src/proto/*.rs | wc -l
26  # Both proto files have complete definitions

2. Framework Library Tests

Status: ✅ 20/20 PASSING (100%)

All core E2E framework components are working:

✅ Framework initialization & cleanup
✅ Service manager creation & configuration
✅ Performance tracking & metrics
✅ ML pipeline test harness
✅ Data generation utilities
✅ Workflow test result handling

3. Build System

Status: ✅ OPERATIONAL

Proto compilation via build.rs is working correctly:

• ✅ Trading Service protos compiled
• ✅ TLI protos compiled separately (no namespace conflicts)
• ✅ ML Training Service protos compiled
• ✅ Config Service protos compiled

🛠️ Fix Implementation Plan

Phase 1: SQLx Cache Generation (60 min)

# 1. Start PostgreSQL
docker-compose up -d postgres

# 2. Run migrations (if not already applied)
cd /home/jgrusewski/Work/foxhunt
cargo sqlx migrate run

# 3. Generate E2E test query cache
cd /home/jgrusewski/Work/foxhunt/tests/e2e
export DATABASE_URL="postgresql://foxhunt:foxhunt_dev_password@localhost:5432/foxhunt"
cargo sqlx prepare --database-url $DATABASE_URL

# Expected output: .sqlx/query-*.json files created

# 4. Verify cache
ls -lh .sqlx/query-*.json | wc -l  # Should show 6+ files

# 5. Rebuild tests
cargo test -p foxhunt_e2e --no-run

Phase 2: Update DQN Test (30 min)

// File: /home/jgrusewski/Work/foxhunt/tests/e2e/tests/dqn_training_test.rs

// Find line 48 and replace with:
let hyperparams = DQNHyperparameters {
    learning_rate: 0.001,
    batch_size: 64,
    gamma: 0.99,
    epsilon_start: 1.0,
    epsilon_end: 0.01,
    epsilon_decay: 0.995,
    buffer_size: 10_000,
    epochs: 5,
    checkpoint_frequency: 2,
    early_stopping_enabled: false,        // Disable for test
    q_value_floor: 0.5,
    min_loss_improvement_pct: 2.0,
    plateau_window: 30,
    min_epochs_before_stopping: 50,
};

Phase 3: Run Tests (30 min)

# 1. Start all services
docker-compose up -d

# 2. Verify services
curl http://localhost:8080/health  # API Gateway
curl http://localhost:8081/health  # Trading Service

# 3. Run library tests (should still pass)
cargo test -p foxhunt_e2e --lib

# 4. Run integration tests (one at a time for debugging)
cargo test -p foxhunt_e2e --test five_service_orchestration_test -- --nocapture

# 5. Run all E2E tests
cargo test -p foxhunt_e2e --no-fail-fast

📈 Expected Outcomes

After Fixes Applied

E2E Test Status: ✅ 20/48 passing (41.7%)

Library Tests:    ✅ 20/20 passing (100%)
Integration Tests: ⏳ 0/28 compiling → expected 15-20/28 passing (54-71%)
                   ⚠️ Some may fail due to service dependencies

Known Test Categories:
├── Service Health Checks (3 tests) - LIKELY PASSING
├── Service Discovery (3 tests) - LIKELY PASSING
├── API Gateway Routing (5 tests) - LIKELY PASSING
├── ML Training Pipeline (4 tests) - MAY FAIL (needs DBN data)
├── Trading Workflows (6 tests) - MAY FAIL (needs running services)
└── Performance & Load Tests (7 tests) - UNLIKELY TO PASS (heavy infra)

Remaining Issues (Post-Fix)

After applying the 3 fixes, we expect:

1. ✅ All tests will compile
2. ⚠️ Some tests will fail at runtime due to:
   • Missing DBN test data files
   • Services not running
   • Database schema migrations not applied
   • Vault configuration issues

These are expected and should be addressed in Agent G20 (Integration Testing) phase.
