# Integration Test Reorganization - Migration History

## Date
December 11, 2025

## Overview
Reorganized integration tests from flat structure to hierarchical organization matching unit test structure.

## Motivation
- Match unit test organization for consistency
- Improve test discoverability
- Reduce cognitive load when navigating tests
- Clear categorization of test types

## Changes

### Before (Flat Structure)
```
tests/integration/database/sql/
├── test_end_to_end_ip_filtering_clean.py
├── test_network_address_filtering.py
├── test_mac_address_filter_operations.py
├── test_end_to_end_ltree_filtering.py
├── test_daterange_filter_operations.py
└── ... (15+ files in flat structure)
```

### After (Hierarchical Structure)
```
tests/integration/database/sql/where/
├── network/
│   ├── test_ip_filtering.py
│   ├── test_ip_operations.py
│   ├── test_mac_filtering.py
│   ├── test_mac_operations.py
│   └── ... (8 files)
├── specialized/
│   ├── test_ltree_filtering.py
│   └── test_ltree_operations.py
├── temporal/
│   ├── test_daterange_filtering.py
│   └── test_daterange_operations.py
├── spatial/
│   └── test_coordinate_operations.py
└── test_mixed_phase4.py (2-4 files in root)
```

| `test_end_to_end_daterange_filtering.py` | `temporal/test_daterange_filtering.py` |

### Spatial Tests (1 file)
| Before | After |
|--------|-------|
| `test_coordinate_filter_operations.py` | `spatial/test_coordinate_operations.py` |

### Mixed Tests (2 files)
| Before | After |
|--------|-------|
| `test_end_to_end_phase4_filtering.py` | `test_mixed_phase4.py` |
| `test_end_to_end_phase5_filtering.py` | `test_mixed_phase5.py` |

**Total: 15 files moved and renamed**

## Impact

### Positive
- ✅ Easier test discovery
- ✅ Consistent with unit test structure
- ✅ Clear categorization
- ✅ Better documentation structure
- ✅ Reduced root directory clutter

### Neutral
- ➖ File paths changed (git history preserved)
- ➖ Import paths unchanged (tests are independent)
- ➖ CI/CD paths unchanged (uses parent directories)

### No Negative Impact
- ✅ Zero test failures from reorganization
- ✅ All tests pass
- ✅ Performance unchanged
- ✅ Git history preserved (used `git mv`)

## Git History
All file moves were done using `git mv` to preserve history.

Use `git log --follow <file>` to see full history.
Use `git blame -C <file>` for line-by-line attribution.

## Related Work
- Unit test reorganization: Phases 1-8 of operator strategies refactor
- Phase plans: `.phases/integration-test-reorganization/`
- Original proposal: Discussion on 2025-12-11

## Future Work
- Add fulltext integration tests when implemented
- Consider similar reorganization for repository tests
- Document test patterns for each category
