Session Buddy

# Test Improvement Plan for Session-Mgmt-MCP ## Overview This document outlines the improvements to be made to the test suite for the session-buddy project. The goal is to enhance test coverage, add more robust testing patterns, and improve overall test quality. ## Current Test Infrastructure Analysis - Comprehensive fixture setup in `conftest.py` - Test helpers in `helpers.py` with utilities for data generation, mocking, and assertions - Well-organized test directories: unit, integration, functional, performance, security - Good async test support using pytest-asyncio - Coverage reporting configured ## Identified Areas for Improvement ### 1. Missing Test Coverage - [ ] Edge cases for error handling in critical components - [ ] Boundary conditions for input validation - [ ] Negative test scenarios - [ ] Exception propagation paths - [ ] Resource cleanup scenarios ### 2. Property-Based Testing - [ ] Use Hypothesis for testing with varied inputs - [ ] Test invariants and properties of system behavior - [ ] Generate complex input data automatically ### 3. Performance Testing - [ ] Add benchmarks for performance-critical operations - [ ] Memory usage monitoring - [ ] Database query performance - [ ] Embedding generation and search performance ### 4. Integration Testing - [ ] End-to-end workflows - [ ] Database interactions - [ ] MCP server integration - [ ] Cross-component interactions ### 5. Security Testing - [ ] Input validation and sanitization - [ ] Permissions and access control - [ ] Data sanitization for sensitive information ## Specific Action Items ### Unit Tests - [ ] Add missing unit tests for uncovered functions - [ ] Create tests for error conditions and edge cases - [ ] Add more comprehensive mocking strategies - [ ] Test reflection storage and retrieval with various data sizes ### Integration Tests - [ ] Test complete session lifecycle: init → checkpoint → end - [ ] Test database operations with real database connections - [ ] Test embedding generation with different content types - [ ] Test git operations with various repository states ### Performance Tests - [ ] Benchmark search operations with large datasets - [ ] Measure memory usage during reflection storage - [ ] Benchmark quality scoring algorithms - [ ] Performance tests for concurrent operations ### Security Tests - [ ] Test for injection vulnerabilities in search - [ ] Validate file handling and path traversal protection - [ ] Test permissions and access control mechanisms ## Implementation Approach ### Phase 1: Basic Coverage Enhancement - Add unit tests for uncovered functions - Address critical edge cases in error handling - Implement basic property-based tests for core functions ### Phase 2: Advanced Testing - Add comprehensive integration tests - Implement performance benchmarks - Add security-focused tests ### Phase 3: Quality Assurance - Set up continuous testing pipeline - Implement test result reporting - Establish test coverage thresholds ## Tools and Techniques - Hypothesis for property-based testing - pytest-benchmark for performance testing - Coverage.py for coverage reporting - pytest-timeout for detecting hanging tests - Mocking with unittest.mock and pytest-mock ## Success Metrics - Increase test coverage to 85%+ for critical modules - Add 50+ new test cases covering edge cases - Implement 10+ property-based tests - Establish performance benchmarks for key operations - Eliminate critical and high severity issues identified by tests ## Timeline - Phase 1: 1 week - Phase 2: 2 weeks - Phase 3: 1 week
