~10-12% gain **Target Files**: `src/api/routes/*.py` (287 statements, 0% coverage) Create integration tests for: 1. **bookings.py** (57 statements) - GET /api/v1/bookings (list with pagination) - GET /api/v1/bookings/{id} (details) - Search and filter operations 2. **listings.py** (139 statements) - GET /api/v1/listings (list with pagination) - GET /api/v1/listings/{id} (details) - Availability checks 3. **auth.py** (26 statements) - POST /api/v1/auth/token - Token refresh flow 4. **analytics.py** (65 statements) - Analytics endpoints **Estimated tests needed**: 40-50 tests **Estimated impact**: +10-12% coverage #### Phase 2: Service Completions - ~4-6% gain **Target Files**: Services with 40-60% coverage 1. **hostaway_client.py** (54 missing lines) - Complete method coverage - Error handling paths 2. **summarization_service.py** (20 missing lines) - Summarization logic - Strategy application 3. **cursor_storage.py** (24 missing lines) - Storage operations - Expiration handling **Estimated tests needed**: 20-30 tests **Estimated impact**: +4-6% coverage #### Phase 3: Utilities - ~2-3% gain **Target Files**: Utils with < 50% coverage 1. **field_projector.py** (19 missing lines) 2. **token_estimator.py** (12 missing lines) **Estimated tests needed**: 10-15 tests **Estimated impact**: +2-3% coverage ### Total Effort to 80% **New Tests Required**: 70-95 additional tests **Estimated Time**: 4-6 hours **Expected Final Coverage**: 80-85% ## Test Quality Metrics ### Code Quality -
