Major improvements:
- app.py coverage: 15% → 25% (+10 percentage points)
- research/guarded_ai.py coverage: 68% → 81% (+13 percentage points)
- Overall project coverage: 68% → 72% (+4 percentage points)
Key changes:
- Add comprehensive Flask integration tests for app.py activity functions
- Test real database operations with in-memory SQLite
- Add extensive guarded_ai.py error handling and client management tests
- Enhanced Makefile with comprehensive test targets
- Updated requirements-test.txt with flake8
- All 135 tests now passing with proper test coverage
The integration tests use real Flask environment, actual YAML processing,
and genuine database operations instead of mocks for accurate coverage.
- Updated validator terminal step detection to only flag truly terminal steps
- Fixed validator to accept integers and booleans in buckets (as supported by app.py)
- Fixed metadata_remove format in activity17 from dictionary to list of strings
- Added proper terminal section to activity3.yaml without questions/buckets
- Fixed missing restart transition and bucket in activity28
- Removed unused game_end transitions from battleship files
- Updated exit transitions to go directly to step_4 (goodbye step)
- Applied black formatting to validator code
All 30 activity YAML files now validate successfully with 0 errors and 0 warnings.
- Add comprehensive testing framework with 67 test cases covering unit, integration, and functional testing
- Create universal YAML validator supporting all activity types with validation for metadata operations, terminal steps, and Python syntax
- Implement proper Makefile with venv management and test runners following unDRY principles for copy-paste engineering
- Add requirements-test.txt for test dependencies separation
- Configure pytest with conftest.py for proper environment variable management
- Update CLAUDE.md with Makefile best practices
- All 67 tests passing with proper mocking of external dependencies
Testing coverage includes:
• Unit tests (37): Core app functions, utilities, navigation, response handling
• Integration tests (20): Complete activity workflows and error handling
• Functional tests (9): Full battleship game scenarios and edge cases
• YAML validator (17): Universal validation for all activity configurations
