+# Phase 5: Testing & Quality - COMPLETE ✅
+
+## Achievement Summary
+
+**Coverage:** 84% (target: 80%) ✅
+**Tests Added:** 108 new tests
+**Total Tests:** 314 (304 run by default + 10 API health checks)
+**Status:** All passing (303 passed, 1 skipped)
+**Runtime:** ~12 seconds
+
+## What Was Done
+
+### 1. Test Coverage Expansion (108 new tests)
+
+Created three comprehensive test modules covering core business logic:
+
+- **test_filters.py** (36 tests)
+  - Property type filtering (exact/partial/case-insensitive)
+  - Numeric range filters (rooms, price, area, floor)
+  - DealFilters model integration
+  - Missing data handling
+  - Error validation
+
+- **test_statistics.py** (32 tests)
+  - Statistical calculations (mean, median, std_dev, percentiles)
+  - Property type distribution
+  - Date handling (date objects + ISO strings)
+  - Missing/zero value handling
+
+- **test_market_analysis.py** (40 tests)
+  - Date parsing and grouping (monthly/quarterly)
+  - Market activity scoring (volume, trends)
+  - Investment potential analysis
+  - Liquidity metrics
+  - Time-independent testing with relative dates
+
+### 2. VCR.py Infrastructure
+
+Set up for recording/replaying HTTP interactions:
+- Created `tests/vcr_config.py` with configuration
+- Added `vcr_cassette` fixture in conftest.py
+- Created `tests/cassettes/` directory
+- Configured request/response scrubbing
+
+### 3. API Health Check Suite (10 tests)
+
+Created `tests/api_health/` with weekly checks:
+- **Autocomplete health** (3 tests): endpoint, structure, coordinates
+- **Deals API health** (3 tests): radius queries, street deals, models
+- **Data quality** (2 tests): reasonable amounts, recent dates
+- **Integration** (2 tests): full workflow, response times
+- Marked with `@pytest.mark.api_health`
+- Run separately: `pytest -m api_health`
+
+## Coverage by Module
+
+| Module | Coverage | Tests |
+|--------|----------|-------|
+| govmap/filters.py | 99% | 36 |
+| govmap/models.py | 97% | 36 |
+| govmap/utils.py | 96% | 42 |
+| govmap/market_analysis.py | 90% | 40 |
+| fastmcp_server.py | 86% | 22 |
+| govmap/statistics.py | 86% | 32 |
+| govmap/client.py | 73% | 34 |
+| **OVERALL** | **84%** | **304** |
+
+## Usage
+
+### Run all tests (default)
+```bash
+pytest tests/
+```
+
+### Run with coverage report
+```bash
+pytest tests/ --cov=nadlan_mcp --cov-report=term-missing
+```
+
+### Run specific test modules
+```bash
+pytest tests/govmap/test_filters.py -v
+pytest tests/govmap/test_statistics.py -v
+pytest tests/govmap/test_market_analysis.py -v
+```
+
+### Run API health checks (weekly)
+```bash
+pytest -m api_health -v
+```
+
+## Key Improvements
+
+1. **Exceeded target** - 84% vs 80% goal
+2. **Fast execution** - 12s for 304 tests
+3. **Time-independent** - Tests use relative dates
+4. **Comprehensive** - All major functions tested
+5. **Maintainable** - Parametrized tests reduce duplication
+6. **Monitored** - Weekly API health checks
+7. **Documented** - Test docstrings explain behavior
+
+## Technical Highlights
+
+### Date Handling
+- Created `get_recent_date()` helper to avoid time-dependent failures
+- All test dates relative to current date
+- Proper date/datetime type handling for Pydantic validation
+
+### Model Testing
+- Tests match actual model fields (not documentation)
+- Handles Pydantic strict validation
+- Tests computed fields (price_per_sqm)
+
+### Edge Cases
+- Zero vs missing values
+- Threshold boundaries (rating edge cases)
+- Evenly distributed data (trend calculations)

+
+## Next Steps
+
+Phase 5 complete! Possible future improvements:
+- Record VCR cassettes for faster integration tests
+- Increase govmap/client.py coverage (error paths)
+- Add mutation testing (pytest-mutagen)
+- Property-based testing (Hypothesis)
+
+## Verification
+
+All tests passing:
+```bash
+$ pytest tests/ -m "not api_health" -q
+303 passed, 1 skipped, 10 deselected in 12.14s
+```
+
+Coverage exceeds target:
+```bash
+$ pytest tests/ --cov=nadlan_mcp
+TOTAL: 84% coverage
+```
+
+API health checks work:
+```bash
+$ pytest -m api_health --collect-only
+10 tests collected
+```
