Test and improve project: Add tests, logging, type hints, and async consistency fixes

[Copilot]

Overview

This PR comprehensively tests and improves the Lumibot project by adding a complete test suite, fixing async/sync inconsistencies, improving code quality with type hints, and adding a professional logging system.

Key Improvements

🔧 Fixed Async/Sync Inconsistency

The project had a critical inconsistency where robots_db.py was using synchronous sqlite3 while the rest of the codebase used asynchronous aiosqlite. This has been fixed:

• Converted robots_db.py to fully async with aiosqlite
• Updated main.py to call init_db() asynchronously
• Updated robots_manager.py to await async database operations

This ensures the entire application is now consistently asynchronous, preventing potential blocking operations.

✅ Added Comprehensive Test Suite (7 Tests)

Created two test files with full coverage of critical functionality:

Unit Tests (test_utils.py):

• URL validation and filtering
• Blacklist detection
• Forbidden pattern detection
• URL depth calculation

Integration Tests (test_integration.py):

• Async database initialization
• Robots.txt storage and retrieval
• Table creation verification

All tests pass successfully ✅

📝 Improved Code Quality

• Added type hints to utils.py, robots_manager.py, and robots_db.py
• Enhanced docstrings with detailed parameter and return value documentation
• Improved exception handling using specific error types instead of bare excepts

📊 Added Logging System

Created a professional logging module (logger.py) with:

• Configurable log levels
• File and console output
• Automatic log directory creation
• Less verbose external library logging

Integrated logging into main.py for better debugging and monitoring.

🔧 Fixed Directory Creation Issues

• Database directories (database/) are now created automatically
• Prevents startup errors for new users
• Added to both database.py and robots_db.py

📦 Modern Python Packaging

Added pyproject.toml with:

• Project metadata and dependencies
• Development dependencies (pytest, black, mypy)
• Build system configuration
• Tool configurations (black, mypy)

📄 Project Hygiene

• Added comprehensive .gitignore (Python artifacts, databases, logs, IDE files)
• Removed accidentally committed __pycache__/ files
• Updated README with testing instructions
• Created IMPROVEMENTS.md with detailed changelog

Testing

Run the test suite with:

python3 -m unittest discover -s . -p "test_*.py" -v

All 7 tests pass with no errors ✅
