  ✓ Task retrieved successfully with correct priority
=== Test 1 PASSED ===

test test_scheduler_temporal_integration ... ok

test result: ok. 1 passed; 0 failed; 0 ignored; 0 measured; 9 filtered out
```

### Full Suite Output
```

test test_deadline_priority_handling ... ok

test result: ok. 10 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out
```

## Troubleshooting

### Issue: Tests Timeout
**Solution**: Run with single thread to avoid resource contention
```bash
cargo test --test integration_tests -- --test-threads=1
```

### Issue: Compilation Errors
**Solution**: Ensure all crates are built first
```bash
cargo build --all
cargo test --test integration_tests
```

### Issue: Test Failures
**Solution**: Run individual tests to isolate issues
```bash
# 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
```bash
# Run without performance tests
cargo test --test integration_tests --skip performance
```

## Test Coverage Verification

### Check What's Tested
```bash
# 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
```bash
# 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
```bash
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

## CI/CD Integration

### GitHub Actions Example
```yaml
name: Integration Tests

on: [push, pull_request]

jobs:
  integration:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Setup Rust
        uses: actions-rs/toolchain@v1
        with:
          toolchain: stable
      - name: Run Integration Tests
        run: cargo test --test integration_tests -- --test-threads=1
```

## Documentation

For detailed test documentation, see:
- `/workspaces/midstream/docs/INTEGRATION_TESTS_SUMMARY.md` - Complete test coverage
- `/workspaces/midstream/tests/integration_tests.rs` - Source code with inline docs

## Support

If tests fail:
1. Check individual test output with `--nocapture`
2. Verify all dependencies are built: `cargo build --all`
3. Review test documentation comments in source
4. Run tests with single thread: `--test-threads=1`
