**`src/services/indexer.py`**: 59.33% (102 missed statements) - Missing coverage for error handling paths - Incomplete testing of file processing edge cases - Performance monitoring code paths not exercised - **`src/services/embedder.py`**: 65.12% (44 missed statements) - Missing tests for embedding batch failures - Error recovery paths not covered - Provider fallback logic not tested - **`src/services/chunker.py`**: 69.62% (34 missed statements) - AST parsing edge cases not covered - Language-specific chunking strategies undertested #### 2. **MCP Tools** (moderate impact) - **`src/mcp/tools/search.py`**: 74.12% (15 missed statements) - **`src/mcp/tools/indexing.py`**: 79.07% (9 missed statements) - **`src/mcp/server_fastmcp.py`**: 48.68% (37 missed statements) #### 3. **Uncovered Modules** (0% coverage) - `src/database.py` (65 statements) - Legacy database module - `src/mcp/errors.py` (25 statements) - Error handling utilities - `src/mcp/logging_example.py` (29 statements) - Example/documentation code - `src/mcp/middleware.py` (67 statements) - MCP middleware ### Test Failures Analysis #### Fixture Scope Mismatch (95 errors) **Root Cause**: Session-scoped fixtures attempting to use function-scoped async fixtures **Affected Tests**: `tests/unit/test_project_id_validation.py` - All security validation tests failing with `ScopeMismatch` error - Tests are correctly written but fixture scope configuration needs adjustment **Example Error**: ``` Failed: ScopeMismatch: You tried to access the function scoped fixture _function_scoped_runner with a session scoped request object ``` **Impact**: 95 test errors in security validation suite (not counted as failures, but preventing execution) #### Contract Validation Failures (58 failures) **Primary Failure**: `test_schema_generation.py::test_search_code_tool_schema_generation` **Issue**: FastMCP schema generation not including all Pydantic field metadata - Missing `type`, `description`, `nullable` properties for optional fields - Missing constraint metadata (`minimum`, `maximum`) for integer fields **Impact**: Contract compliance tests detecting schema generation gaps ### Root Cause Analysis #### Coverage Gap Causes 1. **Test Infrastructure Issues**: - Fixture scope mismatches preventing 95 security tests from running - Contract tests detecting schema generation gaps 2. **Incomplete Test Suites**: - Core services (indexer, embedder, chunker) missing error path testing - MCP tool integration tests incomplete - Legacy modules (database.py, middleware.py) not covered 3. **Pre-existing Baseline**: - Some modules (`logging_example.py`) are documentation/example code - Legacy `database.py` module may be deprecated #### Why Tests Are Failing 1. **Fixture Architecture**: pytest-asyncio fixture scopes incompatible with test class design 2. **FastMCP Integration**: Schema generation not preserving full Pydantic metadata 3. **Integration Test Gaps**: High-level workflows not fully exercised --- ## Constitutional Compliance Assessment ### Principle V: Production Quality **Requirement**: ≥95% test coverage with comprehensive quality verification **Status**: ❌ NOT COMPLIANT - **Current**: 69.64% coverage - **Gap**: 25.36 percentage points below target - **Risk Level**: HIGH - Significant quality assurance gap ### Principle VIII: Pydantic Type Safety **Requirement**: mypy --strict with zero errors **Status**: ✅ COMPLIANT - **Current**: 0 type errors across 31 source files - **Type Safety**: 100% validated - **Risk Level**: NONE - Full type safety achieved --- ## Recommendations ### Immediate Actions (Required for T038 Completion) #### Priority 1: Fix Fixture Scope Issues **File**: `tests/unit/conftest.py` **Action**: Change `engine` fixture from session scope to function scope OR restructure test classes to use function-scoped tests **Impact**: Unlocks 95 security validation tests, improving coverage by ~8-10% #### Priority 2: Complete Core Service Tests **Files**: - `tests/unit/test_indexer.py` - `tests/unit/test_embedder.py` - `tests/unit/test_chunker.py` **Action**: Add error path and edge case tests for: - File processing failures in indexer - Embedding provider fallbacks in embedder - AST parsing edge cases in chunker **Impact**: Estimated +15-20% coverage gain #### Priority 3: Add MCP Tool Integration Tests **Files**: - `tests/integration/test_mcp_tools.py` (enhance) - `tests/contract/test_schema_generation.py` (fix) **Action**: - Fix FastMCP schema generation to include full Pydantic metadata - Add comprehensive MCP tool integration tests **Impact**: Estimated +5-8% coverage gain #### Priority 4: Cover Legacy/Utility Modules **Files**: - `tests/unit/test_database_legacy.py` (NEW) - `tests/unit/test_mcp_errors.py` (NEW) - `tests/unit/test_middleware.py` (NEW) **Action**: Add basic test coverage for utility modules OR mark as deprecated/example code **Impact**: Estimated +5-7% coverage gain ### Long-Term Improvements 1. **Integration Test Strategy**: Add end-to-end workflow tests 2. **Contract Test Maturity**: Ensure FastMCP schema generation preserves all Pydantic metadata 3. **Fixture Architecture Review**: Standardize async fixture scoping patterns 4. **Coverage Monitoring**: Add pre-commit hooks to prevent coverage regression --- ## Estimated Effort to Achieve 95% Coverage | Priority | Tasks | Estimated Effort | Coverage Gain | |----------|-------|------------------|---------------| | P1: Fix Fixtures | 1 task | 1-2 hours | +8-10% | | P2: Core Services | 3 tasks | 4-6 hours | +15-20% | | P3: MCP Tools | 2 tasks | 2-3 hours | +5-8% | | P4: Utilities | 3 tasks | 2-3 hours | +5-7% | | **TOTAL** | **9 tasks** | **9-14 hours** | **+33-45%** | **Projected Final Coverage**: 102.64% - 114.64% (target achievable with full implementation) --- ## Conclusion ### T039 (Type Safety): ✅ PASSING **mypy --strict validation successful** - Zero type errors across all source files. Constitutional Principle VIII fully satisfied. ### T038 (Coverage): ❌ FAILING **Coverage at 69.64%, requiring 25.36 points improvement** to meet 95% target. **Key Blockers**: 1. Fixture scope mismatches preventing 95 security tests from executing 2. Incomplete test suites for core services (indexer, embedder, chunker) 3. Legacy/utility modules without test coverage **Path Forward**: Execute Priority 1-4 recommendations (estimated 9-14 hours) to achieve Constitutional Principle V compliance. --- ## Artifacts Generated - HTML Coverage Report: `htmlcov/index.html` - Coverage XML: `coverage.xml` - This Verification Report: `T038-T039-VERIFICATION-REPORT.md` **Report Generated**: 2025-10-12 20:45:00 UTC
