Quick Test Guide - MidStream Integration Tests

Quick Start

# Run all integration tests
cargo test --test integration_tests

# Run with detailed output
cargo test --test integration_tests -- --nocapture --test-threads=1

# Run specific test
cargo test --test integration_tests test_scheduler_temporal_integration -- --exact

Troubleshooting

Issue: Tests Timeout

Solution: Run with single thread to avoid resource contention

cargo test --test integration_tests -- --test-threads=1

Issue: Compilation Errors

Solution: Ensure all crates are built first

cargo build --all
cargo test --test integration_tests

Issue: Test Failures

Solution: Run individual tests to isolate issues

# Run one test at a time
cargo test --test integration_tests test_scheduler_temporal_integration -- --exact

Issue: Performance Tests Slow

Solution: This is expected - they test 1000+ operations

# Run without performance tests
cargo test --test integration_tests --skip performance

Test Coverage Verification

Check What's Tested

# List all test functions
grep -n "^fn test_" tests/integration_tests.rs

# Count tests
grep -c "^fn test_" tests/integration_tests.rs

View Test Documentation

# Show test descriptions
grep -B2 "^fn test_" tests/integration_tests.rs | grep "///"

Performance Benchmarks

Expected Performance Metrics

Scheduler: 1000 tasks in <100ms (<0.1ms per task)
Temporal Compare: 100-element DTW in <50ms (with caching)
Attractor Analysis: 1000 points analysis in <100ms
Cache Hit Rate: >50% on repeated operations

Run Performance Tests Only

cargo test --test integration_tests test_performance_scalability -- --exact --nocapture

Integration Validation Checklist

✅ Cross-crate integration: Tests use multiple crates together ✅ Real implementations: No mocks, actual published APIs ✅ Error handling: All error paths tested ✅ Performance: Throughput and latency validated ✅ State management: Clear/reset operations work ✅ Real-world scenarios: Practical use cases validated
