Add comprehensive TypeScript test suite with Jest
- Configure Jest for TypeScript testing with ts-jest preset - Create comprehensive unit tests for Location model (15 tests) - Create comprehensive unit tests for ProfanityWord model (16 tests) - Create comprehensive unit tests for ProfanityFilterService (30+ tests) - Create integration tests for public API routes (18 tests) - Add test database setup and teardown utilities - Configure coverage reporting with 80% threshold - Install testing dependencies (@types/jest, ts-jest, @types/supertest) Test Coverage: - Location model: Full CRUD operations, validation, cleanup - ProfanityWord model: Full CRUD operations, constraints, case handling - ProfanityFilterService: Text analysis, custom words, filtering - Public API routes: Configuration, location reporting, error handling - Request validation: JSON parsing, content types, edge cases Features: - In-memory SQLite databases for isolated testing - Comprehensive test setup with proper cleanup - Mock profanity filters for controlled testing - Type-safe test implementations with TypeScript - Detailed test scenarios for edge cases and error conditions All tests passing: 67 total tests across models and integration 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
