test: Add comprehensive tests for code_analyzer.py (22 tests, 90% coverage)
- Created tests/test_code_analyzer.py with 22 comprehensive tests - Python parsing: 8 tests (signatures, type hints, defaults, async, classes, docstrings, decorators, error handling) - JavaScript/TypeScript: 5 tests (functions, arrow functions, classes, type annotations, async) - C++ parsing: 4 tests (function signatures, classes, pointers, defaults) - Depth levels: 3 tests (surface, deep, unknown language) - Integration: 2 tests (public interface, multiple items) Test Coverage: - All 22 tests passing ✅ - 90% code coverage (exceeds 80% target) - Validates Python AST parsing (production-ready) - Documents regex parser limitations for JS/C++ (return types not extracted) Related Issues: - Addresses testing requirements for #64 (C2.2 Docstring extraction) - Addresses testing requirements for #65 (C2.3 Function signatures) Part of TIER 2 implementation plan for C2 Local Codebase Scraping tasks.
