🔍 Failure Analysis

Root Cause #1: Missing Test Data (3 failures)

Error: Failed to read directory: "test_data/real/databento"
Caused by: No such file or directory (os error 2)

• Impact: Low - Tests expect test_data/real/databento directory
• Fix: Create test data fixtures or skip tests when data unavailable
• Workaround: Tests pass when real DBN data is present

Root Cause #2: Statistical Tolerance (3 failures)

• Gradient norm calculations, outlier detection thresholds
• Impact: Low - Edge cases in benchmark validation logic
• Fix: Adjust numerical tolerances for floating-point precision

Root Cause #3: Assertion Logic (4 failures)

• Model weight adjustment, performance tracker, anomaly detection
• Impact: Medium - Business logic assertions need refinement
• Fix: Review test expectations vs actual behavior

🟢 Ignored Tests (14 tests)

• Integration tests requiring external services (Redis, MinIO)
• Performance benchmarks requiring specific hardware
• Tests marked #[ignore] for manual execution

Recommendations

Immediate Actions (Before ML Training Launch)

Priority 1: Fix Trading Service E2E Tests (1-2 hours)

# Fix function signature mismatches
vim services/trading_service/tests/integration_e2e_tests.rs
vim services/trading_service/tests/rollback_automation_tests.rs

# Expected fixes:
# - Update function calls to include missing arguments
# - Fix field visibility issues in RollbackAutomation

Priority 2: Create Test Data Fixtures (30 min)

# Create test data directory structure
mkdir -p test_data/real/databento

# Copy sample DBN files or create minimal fixtures
cp test_data/ES.FUT_sample.dbn test_data/real/databento/

# Or add conditional skipping to tests
#[cfg_attr(not(feature = "real_data_tests"), ignore)]

Priority 3: Investigate ML Test Failures (2-4 hours)

Focus on 10 failing tests:

1. Statistical tests: Review tolerance values
2. Checkpoint tests: Validate signature generation
3. Security tests: Check anomaly detection logic
4. Ensemble tests: Verify weight adjustment calculations

Medium-Term Actions (Next Sprint)

Action 1: Fix ML Examples

• Update model_registry_api.rs to use current candle-core API
• Fix benchmark_cuda_speedup.rs tensor operations
• Timeline: 2-3 hours

Action 2: Clean Up Compiler Warnings

# Apply automated fixes
cargo fix --workspace --allow-dirty --allow-staged

# Manual review of remaining warnings
cargo clippy --workspace -- -D warnings

Action 3: Expand Test Coverage

• Add integration tests for TLS connectivity
• Add end-to-end ensemble prediction tests
• Add paper trading simulation tests
