# Test Coverage Report - Phase 3 Refactoring
|
||||
|
||||
**Generated:** 2025-10-25
|
||||
**Branch:** phase-3
|
||||
**Total Tests:** 34 (all passing in 0.14s)
|
||||
|
||||
## Executive Summary
|
||||
|
||||
✅ **Overall Status:** GOOD - Most functionality is well-tested
|
||||
⚠️ **Concerns:** 1 bug found in `autocomplete_address` MCP tool, some modules lack direct unit tests
|
||||
📊 **Coverage:** Indirect coverage is good through integration tests, but direct unit tests for new modules would improve testability
|
||||
|
||||
## Test Coverage by Module
|
||||
|
||||
### ✅ Well Tested (Indirect Coverage via Integration Tests)
|
||||
|
||||
| Module | Functions | Test Coverage | Notes |
|
||||
|--------|-----------|---------------|-------|
|
||||
| `client.py` | 9 API methods | ✅ High | Tested through GovmapClient integration tests |
|
||||
| `filters.py` | `filter_deals_by_criteria` | ✅ High | 8 dedicated tests covering all filter types |
|
||||
| `statistics.py` | `calculate_deal_statistics`, `calculate_std_dev` | ✅ Good | 1 dedicated test, used in other tests |
|
||||
| `market_analysis.py` | 4 functions | ✅ High | 6 dedicated tests for market analysis |
|
||||
| `utils.py` | `is_same_building` | ✅ Good | 1 dedicated test |
|
||||
|
||||
### ⚠️ Missing Direct Unit Tests
|
||||
|
||||
| Module | Functions | Test Coverage | Impact | Recommendation |
|
||||
|--------|-----------|---------------|--------|----------------|
|
||||
| `validators.py` | 4 validation functions | ⚠️ Indirect only | Low | Add unit tests for edge cases |
|
||||
| `utils.py` | `calculate_distance`, `extract_floor_number` | ⚠️ Indirect only | Low | Add unit tests for Hebrew floor parsing |
|
||||
| `market_analysis.py` | `parse_deal_dates` (helper) | ⚠️ Indirect only | Low | Already tested via parent functions |
|
||||
|
||||
## E2E Test Results (MCP Tools)
|
||||
|
||||
Tested the following MCP tools with real data:
|
||||
|
||||
### ✅ Passing E2E Tests
|
||||
|
||||
1. **`find_recent_deals_for_address`**
|
||||
- Input: `"הרצל 1 תל אביב"`, 1 year, 100m radius, max 5 deals
|
||||
- Result: ✅ SUCCESS - Returned 5 deals with complete statistics
|
||||
- Data Quality: Excellent - all fields populated correctly
|
||||
|
||||
2. **`analyze_market_trends`**
|
||||
- Input: `"דיזנגוף 50 תל אביב"`, 2 years
|
||||
- Result: ✅ SUCCESS - Returned 82 deals analyzed
|
||||
- Output: Comprehensive yearly trends, property type breakdown, neighborhoods
|
||||
- Data Quality: Excellent
|
||||
|
||||
3. **`get_valuation_comparables`**
|
||||
- Input: `"רוטשילד 1 תל אביב"`, property_type="דירה", rooms 2-4, max 5
|
||||
- Result: ✅ SUCCESS - Returned 1 comparable with statistics
|
||||
- Filtering: ✅ Working correctly (rooms, property type)
|
||||
- Token Usage: ✅ Optimized (no bloat fields)
|
||||
|
||||
### ❌ Bug Found: `autocomplete_address`
|
||||
|
||||
**Status:** 🐛 BUG - Incorrect field mapping
|
||||
|
||||
**Problem:**
|
||||
The `autocomplete_address` tool in `fastmcp_server.py` uses incorrect field names when parsing the API response.
|
||||
|
||||
**Current Code (WRONG):**
|
||||
```python
|
||||
formatted_results.append({
|
||||
"address": result.get("addressLabel", ""), # ❌ Wrong field
|
||||
"settlement": result.get("settlementNameHeb", ""), # ❌ Wrong field
|
||||
"coordinates": result.get("coordinates", {}), # ❌ Wrong field
|
||||
"polygon_id": result.get("polygon_id") # ❌ Wrong field
|
||||
})
|
||||
```
|
||||
|
||||
**Actual API Response Fields:**
|
||||
```python
|
||||
{
|
||||
"id": "address|ADDR|123|test",
|
||||
"text": "תל אביב", # ✅ Use this for address
|
||||
"type": "address",
|
||||
"score": 100,
|
||||
"shape": "POINT(3870000.123 3770000.456)", # ✅ Parse this for coordinates
|
||||
"data": {}
|
||||
}
|
||||
```
|
||||
|
||||
**Impact:** HIGH - The tool returns empty data for all fields
|
||||
|
||||
**Fix Required:**
|
||||
```python
|
||||
# Parse coordinates from WKT POINT format
|
||||
shape_str = result.get("shape", "")
|
||||
coordinates = {}
|
||||
if shape_str.startswith("POINT("):
|
||||
coords_str = shape_str[6:-1] # Remove "POINT(" and ")"
|
||||
coords = coords_str.split()
|
||||
if len(coords) == 2:
|
||||
coordinates = {
|
||||
"longitude": float(coords[0]),
|
||||
"latitude": float(coords[1])
|
||||
}
|
||||
|
||||
formatted_results.append({
|
||||
"text": result.get("text", ""), # ✅ Display text
|
||||
"id": result.get("id", ""), # ✅ Unique ID
|
||||
"type": result.get("type", ""), # ✅ Result type
|
||||
"score": result.get("score", 0), # ✅ Match score
|
||||
"coordinates": coordinates # ✅ Parsed coordinates
|
||||
})
|
||||
```
|
||||
|
||||
## Test Organization
|
||||
|
||||
### Current Structure ✅
|
||||
```
|
||||
tests/
|
||||
└── test_govmap_client.py (34 tests)
|
||||
├── TestGovmapClient (12 tests)
|
||||
└── TestMarketAnalysisFunctions (22 tests)
|
||||
```
|
||||
|
||||
### Recommended Structure 📋
|
||||
```
|
||||
tests/
|
||||
├── test_govmap_client.py (existing integration tests)
|
||||
├── govmap/
|
||||

```
|
||||
|
||||
## Missing Test Cases
|
||||
|
||||
### High Priority
|
||||
|
||||
1. **Validator Edge Cases**
|
||||
```python
|
||||
# validators.py
|
||||
- Test validate_address with empty string
|
||||
- Test validate_address with very long address (>500 chars)
|
||||
- Test validate_coordinates with out-of-bounds ITM coordinates
|
||||
- Test validate_positive_int with negative numbers
|
||||
- Test validate_deal_type with invalid types (3, 0, -1)
|
||||
```
|
||||
|
||||
2. **Utils Hebrew Floor Parsing**
|
||||
```python
|
||||
# utils.py
|
||||
- Test extract_floor_number with all Hebrew floor names
|
||||
- Test extract_floor_number with numeric strings
|
||||
- Test extract_floor_number with invalid input
|
||||
- Test calculate_distance with same point
|
||||
- Test calculate_distance with far points
|
||||
```
|
||||
|
||||
3. **MCP Tool E2E Tests**
|
||||
```python
|
||||
# test_fastmcp_tools.py
|
||||
- Test autocomplete_address with real API
|
||||
- Test get_deals_by_radius with edge coordinates
|
||||
- Test error handling for all tools
|
||||
- Test token limits for large responses
|
||||
```
|
||||
|
||||
### Medium Priority
|
||||
|
||||
4. **Client Error Handling**
|
||||
```python
|
||||
# client.py
|
||||
- Test retry logic with transient failures
|
||||
- Test rate limiting behavior
|
||||
- Test timeout handling
|
||||
- Test invalid API responses
|
||||
```
|
||||
|
||||
5. **Filter Edge Cases**
|
||||
```python
|
||||
# filters.py
|
||||
- Test filtering with all null values
|
||||
- Test filtering with overlapping criteria
|
||||
- Test filtering with no matches
|
||||
```
|
||||
|
||||
### Low Priority
|
||||
|
||||
6. **Integration Tests**
|
||||
```python
|
||||
# Integration with real API
|
||||
- Test full workflow: autocomplete → find deals → analyze
|
||||
- Test with various Israeli cities
|
||||
- Test with English addresses
|
||||
```
