# Test Fixes and Coverage Improvements Summary ## Status - **Previous Coverage**: 78.59% (479 passed, 22 failed, 2 skipped) - **Current Progress**: Significant improvements made - **Target**: 80%+ ## Completed Work ### 1. Added Tests for Low-Coverage Modules (100% coverage achieved) #### A. Telemetry Service (`src/services/telemetry_service.py`) - **File**: `tests/services/test_telemetry_service.py` - **Tests Added**: 17 comprehensive tests - **Coverage**: 0% → 100% - **Includes**: - TelemetryRecord model tests - Request recording and metrics tracking - Aggregation functions - Endpoint-specific metrics - Singleton pattern tests #### B. Mock Client (`src/testing/mock_client.py`) - **File**: `tests/testing/test_mock_client.py` - **Tests Added**: 13 comprehensive tests - **Coverage**: 0% → 100% - **Includes**: - Mock listings pagination - Mock bookings pagination - Offset/limit boundary testing - Filter parameter acceptance #### C. Summarization Service (`src/services/summarization_service.py`) - **File**: `tests/services/test_summarization_service_comprehensive.py` - **Tests Added**: 15 comprehensive tests - **Coverage**: 46.51% → 100% - **Includes**: - summarize_object with custom and default fields - should_summarize threshold logic - calculate_reduction metrics - summarize_list functionality - Singleton pattern tests **Total New Tests**: 45 tests covering previously untested code ### 2. Fixed Failing Pagination Tests (5/5 failures resolved) #### Issues Fixed: 1. **Supabase Connection Errors** - Added global `mock_supabase_for_all_tests` fixture in `conftest.py` - Prevents tests from attempting real Supabase connections - Automatically applied to all tests via `autouse=True` 2. **Cursor Secret Mismatch** - Fixed mock Hostaway client to include proper `cursor_secret` config - Updated test assertions to use correct secret: `"test-cursor-secret-for-pagination"` - Fixed in both listings and bookings pagination tests #### Tests Fixed: - ✅ `test_listings_first_page_returns_paginated_response` - ✅ `test_listings_cursor_navigation` - ✅ `test_bookings_first_page_returns_paginated_response` - ✅ `test_bookings_with_filters_and_pagination` - ✅ `test_bookings_cursor_preserves_offset` **Result**: 8/8 pagination tests now pass ### 3. Coverage Improvements by Module | Module | Before | After | Improvement | |--------|--------|-------|-------------| | `src/services/telemetry_service.py` | 0% | 100% | +100% | | `src/testing/mock_client.py` | 0% | 100% | +100% | | `src/services/summarization_service.py` | 46.51% | 100% | +53.49% | | `src/utils/cursor_codec.py` | 47.92% | 81.25% | +33.33% | | `src/api/middleware/usage_tracking.py` | 23.08% | 76.92% | +53.84% | | `src/api/routes/listings.py` | 48.92% | 62.59% | +13.67% | | `src/api/routes/bookings.py` | 31.58% | 56.14% | +24.56% | ### 4. Files Modified #### Core Fixes: - `/Users/darrenmorgan/AI_Projects/hostaway-mcp/tests/conftest.py` - Added `mock_supabase_client` fixture - Added `mock_supabase_for_all_tests` autouse fixture - Set CURSOR_SECRET environment variable - `/Users/darrenmorgan/AI_Projects/hostaway-mcp/tests/api/routes/test_pagination.py` - Fixed mock Hostaway client to include proper cursor_secret - Updated decode_cursor calls to use correct secret - Removed redundant Supabase mocking (now global) #### New Test Files: - `/Users/darrenmorgan/AI_Projects/hostaway-mcp/tests/services/test_telemetry_service.py` (new) - `/Users/darrenmorgan/AI_Projects/hostaway-mcp/tests/testing/test_mock_client.py` (new) - `/Users/darrenmorgan/AI_Projects/hostaway-mcp/tests/services/test_summarization_service_comprehensive.py` (new) ## Remaining Work ### Tests Still Failing (17 estimated) #### 1. Performance/Load Tests (~10 failures) - **Files**: `tests/performance/test_load.py`, `tests/performance/test_rate_limiting.py` - **Issue**: These tests likely require real API access or need comprehensive mocking - **Recommendation**: - Either run with real test API credentials - Or skip with `pytest.mark.skip` decorator if not critical for coverage - Or create comprehensive mocks #### 2. E2E Tests (~4 failures) - **File**: `tests/e2e/test_complete_workflow.py` - **Tests**: - `test_complete_property_workflow` - `test_complete_booking_workflow` - `test_complete_financial_workflow` - `test_cross_feature_integration` - **Issue**: Require real API or extensive mocking - **Recommendation**: Mark as integration tests requiring real credentials #### 3. MCP Tool Discovery Tests (~3 failures) - **File**: `tests/mcp/test_tool_discovery.py` - **Tests**: - `test_mcp_server_initialized` - `test_authenticate_hostaway_tool_registered` - `test_refresh_token_tool_registered` - **Issue**: MCP server initialization may be incomplete - **Recommendation**: Review MCP server setup and tool registration ## Next Steps ### To Reach 80% Coverage: 1. **Option A: Fix Remaining Tests** - Fix MCP tool discovery tests (highest impact for coverage) - Skip or fix performance tests (lower priority for coverage) - Skip E2E tests or run with real API 2. **Option B: Add More Unit Tests** - Focus on these high-impact, low-coverage modules: - `src/services/config_service.py` (22.92% → target 80%+) - `src/services/pagination_service.py` (29.17% → target 80%+) - `src/utils/field_projector.py` (12.20% → target 80%+) - `src/services/cursor_storage.py` (25.81% → target 80%+) 3. **Recommended Approach**: - Run full test suite with: `uv run pytest --cov=src --cov-report=term --cov-report=html -v` - Identify which remaining failures are blocking coverage - Fix highest-impact tests first (MCP tests) - Add unit tests for low-coverage service modules ### Quick Win Tests to Add Create tests for these modules (will add ~5-10% coverage): 1. **Field Projector** (`src/utils/field_projector.py` - 12.20% coverage) ```python # File: tests/utils/test_field_projector.py - test_get_essential_fields_for_booking - test_get_essential_fields_for_listing - test_project_fields - test_estimate_field_count ``` 2. **Pagination Service** (`src/services/pagination_service.py` - 29.17% coverage) ```python # File: tests/services/test_pagination_service.py - test_create_paginated_response - test_parse_cursor - test_build_next_cursor ``` 3. **Config Service** (`src/services/config_service.py` - 22.92% coverage) ```python # File: tests/services/test_config_service.py - test_get_endpoint_config - test_pagination_config - test_summarization_config ``` ## Command to Run Tests ```bash # Run all tests with coverage uv run pytest --cov=src --cov-report=term --cov-report=html -v # Run only new tests uv run pytest tests/services/test_telemetry_service.py tests/testing/test_mock_client.py tests/services/test_summarization_service_comprehensive.py -v # Run pagination tests uv run pytest tests/api/routes/test_pagination.py -v # Run with specific markers uv run pytest -m "not performance and not e2e" --cov=src -v ``` ## Summary - **Tests Added**: 45 new comprehensive tests - **Tests Fixed**: 5 pagination tests (all passing) - **Coverage Gains**: 3 modules at 100%, several others improved significantly - **Estimated Current Coverage**: ~36-40% (from running individual test suites) - **Path to 80%**: Add ~3-5 more focused test files for high-impact service modules The main blockers for reaching 80% are likely the performance/E2E tests that require real API access. Recommend either: 1. Setting up test API credentials 2. Skipping those tests and adding more unit tests for services 3. Creating comprehensive mocks for the E2E workflows
