# Test Improvements Summary

## Overview

The test suite for the session-buddy project has been significantly improved with the following additions:

## 1. Property-Based Tests

- Added comprehensive property-based tests using Hypothesis in `tests/unit/test_utilities_property_based.py`
- Tests for reflection storage and retrieval properties
- Tests for similarity search behavior
- Tests for embedding generation consistency
- Tests for database operations with various inputs

## 2. Performance and Benchmarking Tests

- Created `tests/performance/test_performance_benchmarks.py`
- Added benchmarks for reflection storage performance
- Added performance tests for similarity search with various dataset sizes
- Added tests for large dataset performance (up to 500 reflections)
- Added concurrent operations performance tests
- Added basic memory usage stability tests

## 3. Edge Case and Error Condition Tests

- Created `tests/unit/test_session_manager_edge_cases.py`
- Tests for empty and nonexistent directories
- Tests for permission errors and restricted access
- Tests for malformed project files
- Tests for missing dependencies (like UV package manager)
- Tests for operations with no Git repository
- Tests for timeout conditions and hanging operations
- Tests for unusually large inputs

## 4. Integration Tests

- Enhanced `tests/integration/test_session_complete_workflow.py`
- Complete session lifecycle tests (init → checkpoint → end)
- Tests combining session operations with reflection database
- Tests for permission and trust operations
- Integration with quality scoring system
- Tests for concurrent session operations
- Integration with search functionality
- Tests with actual Git repository operations
- Error recovery tests

## 5. Security Tests

- Created `tests/security/test_security.py`
- Path traversal protection tests
- SQL injection prevention in search operations
- Tests for executable content storage
- Large content handling to prevent resource exhaustion
- Special character handling tests
- Reflection ID manipulation protection
- Environment variable injection prevention

## 6. Documentation

- Created `test_improvement_plan.md` - detailed plan for all improvements
- Created `test_improvements_documentation.md` - documentation of all improvements made

## Results

- All new tests are passing
- Edge case tests now handle expected exceptions gracefully
- Property-based tests ensure system invariants hold for various inputs
- Performance tests establish benchmarks for key operations
- Security tests verify protection against common vulnerabilities
- Integration tests validate complete workflows

The test suite now provides comprehensive coverage across unit, integration, performance, security, and edge cases, significantly improving the reliability and maintainability of the session-buddy project.
