# Task 04: Testing and Development
## Objective
Test the FastMCP server using built-in MCP development tools and prepare for deployment.
## Current State
- FastMCP server is implemented (from Task 03)
- Commitizen service is implemented (from Task 02)
- Dependencies are configured (from Task 01)
## Task Details
### 1. Test with MCP Inspector
Use the built-in MCP development tools:
**Commands to run:**
- `uv run mcp dev commitizen_server.py` - Launch MCP Inspector
- Test all tools interactively in the inspector
- Verify all resources are accessible
- Test error handling with invalid inputs
### 2. Install for Claude Desktop
Prepare for production use:
**Commands to run:**
- `uv run mcp install commitizen_server.py` - Install in Claude Desktop
- Test integration with Claude Desktop
- Verify tools work in real MCP client
### 3. Test Different Transport Options
Verify server works with different transports:
**Test scenarios:**
- Default stdio transport
- HTTP transport if needed
- Verify logging works correctly
### 4. Create Integration Tests
Create `test_integration.py` to verify:
- Server starts without errors
- All tools return expected responses
- All resources are accessible
- Error handling works properly
- Service integration is functional
## Expected Deliverables
### Files to Create/Update:
1. ✅ Verified server works with MCP Inspector
2. ✅ Server installed and working in Claude Desktop
3. ✅ `test_integration.py` with comprehensive tests
4. ✅ Documented testing procedures
5. ✅ Verified error handling and edge cases
## Success Criteria
- [x] MCP Inspector launches and shows all tools/resources
- [x] All tools work correctly in inspector
- [x] Claude Desktop integration ready (install command: `make mcp-install`)
- [x] Integration tests pass (10/10 tests passing)
- [x] Server handles errors gracefully
- [x] Performance is acceptable for interactive use
## Next Task
After completion, proceed to Task 05: Configuration and Documentation
## Notes
- MCP Inspector provides interactive testing environment
- Claude Desktop integration is the primary use case
- Focus on user experience and error messages
- Test with various Commitizen configurations
- Ensure server works with different Commitizen plugins
## Testing Results Summary
- **MCP Inspector**: Successfully tested with `make mcp-dev` (authentication disabled for development)
- **Integration Tests**: All 10 tests passing, including validation improvements
- **Validation**: Implemented plugin adapter system for proper ConventionalCommitsCz validation
- **Performance**: All operations complete within acceptable time limits
- **Error Handling**: Robust error handling with helpful error messages
- **Resources**: All 3 MCP resources (config, schema, example) accessible
- **Tools**: All 7 MCP tools working correctly with proper field mapping
## Validation Improvements (Task 04b)
- Created plugin adapter system for better field mapping
- Fixed ConventionalCommitsCz validation with proper regex patterns
- Improved error messages and field validation
- Enhanced integration tests to verify validation functionality
