Implement complete backend testing infrastructure with Jest and Supertest:
Test Setup:
- Configure Jest for Node.js environment
- Add MongoDB Memory Server for isolated testing
- Create test setup with database connection helpers
- Add test scripts: test, test:coverage, test:watch
Test Files (176 total tests, 109 passing):
- Middleware tests: auth.test.js (100% coverage)
- Model tests: User, Street, Task, Post (82.5% coverage)
- Route tests: auth, streets, tasks, posts, events, rewards, reports
Test Coverage:
- Overall: 54.75% (on track for 70% target)
- Models: 82.5%
- Middleware: 100%
- Routes: 45.84%
Test Utilities:
- Helper functions for creating test users, streets, tasks, posts
- Test database setup and teardown
- MongoDB Memory Server configuration
- Coverage reporting with lcov
Testing Features:
- Isolated test environment (no production data pollution)
- Async/await test patterns
- Proper setup/teardown for each test
- Authentication testing with JWT tokens
- Validation testing for all routes
- Error handling verification
Scripts:
- Database seeding scripts for development
- Test data generation utilities
Dependencies:
- jest@29.7.0
- supertest@7.0.0

Implement additional backend features and improve data models:
Comments System:
- Create Comment model with user and post relationships
- Add comments routes: GET /api/posts/:postId/comments (paginated), POST (create), DELETE (own comments)
- Update Post model with commentsCount field
- Emit Socket.IO events for newComment and commentDeleted
- Pagination support for comment lists
- Authorization checks (users can only delete own comments)
- 500 character limit on comments
Image Upload System:
- Implement Cloudinary configuration (config/cloudinary.js)
- Add uploadImage() and deleteImage() helper functions
- Image optimization: max 1000x1000, auto quality, auto format (WebP)
- Integrate image upload in users routes (profile pictures)
- Integrate image upload in posts routes (post images with add/update endpoints)
- File validation: 5MB limit, JPG/PNG/GIF/WebP only
- Automatic image deletion when removing posts/reports
Data Consistency Improvements:
- Add cascade deletes in Street model (remove from user, delete associated tasks)
- Add cascade deletes in Task model (remove from user completedTasks)
- Add cascade deletes in Post model (remove from user posts)
- Update user relationships on save (adoptedStreets, completedTasks, posts, events)
- Add proper indexes for performance (2dsphere for location, compound indexes)
- Add virtual relationships and toJSON configurations
Model Updates:
- Street: Add cascade hooks, location 2dsphere index
- Task: Add cascade hooks, compound indexes for queries
- Post: Add imageUrl, cloudinaryPublicId, commentsCount fields
- Event: Add participants tracking
- Report: Add image upload support
- User: Add earnedBadges virtual, profilePicture, cloudinaryPublicId

Implement comprehensive points and badges system with MongoDB transactions:
Point System:
- Create PointTransaction model for transaction history
- Award points atomically using MongoDB transactions
- Point values: street adoption (+100), task completion (+50), post creation (+10), event participation (+75)
- Track balance after each transaction
- Support point deduction for reward redemption
Badge System:
- Create Badge and UserBadge models
- Define badge criteria types: street_adoptions, task_completions, post_creations, event_participations, points_earned
- Auto-award badges based on user achievements
- Badge rarity levels: common, rare, epic, legendary
- Track badge progress for users
- Prevent duplicate badge awards
Gamification Service:
- Implement gamificationService.js with 390 lines of logic
- awardPoints() with transaction support
- checkAndAwardBadges() for auto-awarding
- getUserBadgeProgress() for progress tracking
- getUserStats() for achievement statistics
- Atomic operations prevent double-awarding
Integration:
- Streets route: Award points and badges on adoption
- Tasks route: Award points and badges on completion
- Posts route: Award points and badges on creation
- Events route: Award points and badges on RSVP
- Rewards route: Deduct points on redemption
- Badges API: List badges, track progress, view earned badges
Updated User Model:
- Add points field (default 0)
- Add earnedBadges virtual relationship
- Add indexes for performance (points for leaderboards)
