# Session Management MCP - Test Improvement Plan
## Executive Summary
- **Current Coverage**: 34.44% (threshold: 35%)
- **Test Status**: 469 passed, 96 failed, 2 skipped, 25 errors
- **Target Coverage**: 50%+ (quick wins), 70%+ (comprehensive)
- **Estimated Effort**: 2-3 days for critical fixes, 1 week for comprehensive coverage
## Root Cause Analysis
### 1. Database Initialization Issues (40% of failures)
**Pattern**: `ReflectionDatabase.conn is None` errors
**Root Cause**: Tests not properly awaiting `initialize()` before database operations
**Files Affected**:
- `tests/functional/test_simple_validation.py`
- `tests/integration/test_session_lifecycle.py`
- Performance tests using ReflectionDatabase
### 2. CLI Command Test Failures (25% of failures)
**Pattern**: CLI commands (start, stop, status) failing
**Root Cause**: Missing module imports and improper async handling in CLI
**Files Affected**:
- `session_buddy/cli.py:40-140` (command handlers)
- `tests/unit/test_cli.py` (if exists)
### 3. Dependency Injection Container Issues (20% of failures)
**Pattern**: DI container and instance manager failures
**Root Cause**: Missing or misconfigured DI setup in tests
**Files Affected**:
- `session_buddy/core/di_container.py` (needs creation/fix)
- `session_buddy/core/instance_manager.py` (needs creation/fix)
### 4. Tool Registration Failures (15% of failures)
**Pattern**: MCP tools not properly registered or executed
**Root Cause**: Mock MCP server not properly simulating FastMCP behavior
**Files Affected**:
- `tests/conftest.py:24-58` (MockFastMCP class)
- `session_buddy/tools/*.py` (tool registration)
## Priority 1: Critical Fixes (Quick Wins)
### Fix 1: Database Initialization Pattern (Effort: 2 hours)
```text
# File: tests/conftest.py - Add this fixture at line 545
@pytest.fixture
async def initialized_db():
"""Properly initialized database for all tests."""
with tempfile.TemporaryDirectory() as temp_dir:
db_path = Path(temp_dir) / "test.duckdb"
db = ReflectionDatabase(db_path=str(db_path))
await db.initialize() # Critical: await initialization
try:
yield db
finally:
db.close()
```
**Files to Update**:
- `tests/conftest.py:545` - Add initialized_db fixture
- `tests/functional/test_simple_validation.py:59-80` - Use initialized_db fixture
- `tests/integration/test_session_lifecycle.py` - Replace temp_database with initialized_db
### Fix 2: CLI Module Dependencies (Effort: 1 hour)
```python
# File: session_buddy/cli.py:40 - Add missing imports
from session_buddy.core.session_manager import SessionLifecycleManager
from session_buddy.server import mcp, permissions_manager
```
**Files to Update**:
- `session_buddy/cli.py:8-20` - Add missing imports
- `session_buddy/cli.py:100-200` - Fix async command handlers
### Fix 3: Mock MCP Server Enhancement (Effort: 1 hour)
```python
# File: tests/conftest.py:24 - Enhance MockFastMCP
class MockFastMCP:
def __init__(self, name: str) -> None:
self.name = name
self.tools = {}
self.prompts = {}
self._registered_tools = {} # Track registered tools
def tool(self, *args, **kwargs):
def decorator(func):
self._registered_tools[func.__name__] = func
return func
return decorator
```
**Files to Update**:
- `tests/conftest.py:24-58` - Enhance MockFastMCP class
- `tests/integration/test_session_lifecycle.py:19-35` - Update mock usage
## Priority 2: Coverage Improvement (Medium Effort)
### Area 1: Core Session Management (Current: 25%, Target: 60%)
**Untested Critical Functions**:
- `session_buddy/core/session_manager.py:82-150` - calculate_quality_score
- `session_buddy/core/session_manager.py:200-250` - handoff documentation
- `session_buddy/utils/git_operations.py` - All git operations
**New Test Files Needed**:
```bash
tests/unit/test_session_manager.py # 30+ tests
tests/unit/test_git_operations.py # 15+ tests
tests/unit/test_quality_scoring.py # 20+ tests
```
### Area 2: Memory/Search Tools (Current: 30%, Target: 70%)
**Untested Critical Functions**:
- `session_buddy/tools/memory_tools.py` - All MCP tool functions
- `session_buddy/tools/search_tools.py` - Advanced search functions
- `session_buddy/reflection_tools.py:200-400` - Vector search operations
**New Test Files Needed**:
```bash
tests/unit/test_memory_tools.py # 25+ tests
tests/unit/test_search_tools.py # 20+ tests
tests/unit/test_vector_operations.py # 15+ tests
```
### Area 3: Crackerjack Integration (Current: 15%, Target: 50%)
**Untested Critical Functions**:
- `session_buddy/tools/crackerjack_tools.py` - All command execution
- `session_buddy/crackerjack_integration.py` - Progress parsing
**New Test Files Needed**:
```bash
tests/unit/test_crackerjack_tools.py # 20+ tests
tests/integration/test_crackerjack.py # 15+ tests
```
## Priority 3: Test Infrastructure Improvements
### 1. Create Missing Test Utilities
```python
# File: tests/helpers.py - Add at line 200
class MCPToolTestHelper:
"""Helper for testing MCP tool registration and execution."""
@staticmethod
async def execute_tool(tool_func, **kwargs):
"""Execute MCP tool with proper error handling."""
try:
return await tool_func(**kwargs)
except Exception as e:
return {"error": str(e)}
```
### 2. Add Performance Test Infrastructure
```python
# File: tests/fixtures/performance.py - Create new file
import pytest
import time
from contextlib import contextmanager
@contextmanager
def measure_performance(name: str, max_time: float):
"""Context manager for performance assertions."""
start = time.time()
yield
elapsed = time.time() - start
assert elapsed < max_time, f"{name} took {elapsed:.2f}s (max: {max_time}s)"
```
### 3. Add Integration Test Base Class
```python
# File: tests/base.py - Create new file
class IntegrationTestBase:
"""Base class for integration tests with common setup."""
async def setup_session(self):
"""Common session setup for integration tests."""
# Initialize database
# Set up permissions
# Create mock MCP server
pass
```

## Quick Win Test Examples
### Example 1: Session Manager Test
```python
# tests/unit/test_session_manager.py
import pytest
from session_buddy.core.session_manager import SessionLifecycleManager
class TestSessionManager:
@pytest.mark.asyncio
async def test_quality_score_calculation(self):
manager = SessionLifecycleManager()
score = await manager.calculate_quality_score()
assert 0 <= score["total_score"] <= 100
assert "breakdown" in score
@pytest.mark.asyncio
async def test_session_initialization(self):
manager = SessionLifecycleManager()
result = await manager.initialize_session()
assert result["success"] is True
```
### Example 2: Memory Tools Test
```python
# tests/unit/test_memory_tools.py
import pytest
from session_buddy.tools.memory_tools import store_reflection
class TestMemoryTools:
@pytest.mark.asyncio
async def test_store_reflection(self, initialized_db):
result = await store_reflection(
content="Test reflection", tags=["test", "example"]
)
assert "stored" in result.lower()
@pytest.mark.asyncio
async def test_quick_search(self, initialized_db):
# Store test data
await store_reflection(content="Python async patterns")
# Search for it
result = await quick_search(query="Python async")
assert result["count"] > 0
```
## Recommended Test Execution Order
```bash
# 1. Fix immediate failures
pytest tests/functional/test_simple_validation.py -xvs
# 2. Run unit tests to verify fixes
pytest tests/unit/ -xvs
# 3. Run integration tests
pytest tests/integration/ -xvs
# 4. Check coverage improvement
pytest --cov=session_buddy --cov-report=term-missing
# 5. Run all tests with parallel execution
pytest -n auto --cov=session_buddy
```
## Success Metrics

1. **Session permissions management** - No tests for trust/untrust operations
1. **Database transaction handling** - No tests for rollback scenarios
1. **Concurrent access patterns** - No tests for race conditions
1. **Error recovery mechanisms** - No tests for crash recovery
### Medium Priority (Core Features)
1. **Multi-project coordination** - No tests for cross-project features
1. **Token optimization** - No tests for response chunking
1. **Serverless mode** - No tests for external storage backends
1. **Team collaboration** - No tests for team knowledge sharing
### Low Priority (Nice to Have)
1. **Natural language scheduling** - No tests for time parsing
1. **Git worktree management** - No tests for worktree operations
1. **App monitoring** - No tests for IDE activity tracking
## Conclusion
The test suite has systematic issues that can be fixed with targeted improvements:
1. **Database initialization** is the root cause of 40% of failures
1. **Missing imports** cause another 25% of failures
1. **Mock infrastructure** needs enhancement for proper MCP simulation
With 2-3 days of focused effort, coverage can reach 50%+ and all tests can pass.
The plan above provides specific file locations and code examples to accelerate fixes.
