Enhanced Todo Model: Robust Validation and Flexible Creation

Description

Summary of Work

This pull request introduces a comprehensive enhancement to our Todo model, focusing on improving validation, flexibility, and overall code quality.

Motivation

Our Todo application requires a robust and flexible data model that can handle various use cases while maintaining strict data integrity. This update addresses key requirements for todo item management, ensuring consistent and reliable todo creation across the application.

Key Improvements

• Implemented comprehensive input validation
• Added flexible todo creation methods
• Enhanced test coverage for edge cases
• Improved data integrity through strict constraints

Business Value

• Prevents invalid todo creation
• Reduces potential runtime errors
• Provides clear, predictable todo object behavior
• Supports future scalability of the todo management system

Changes Made

Functional Changes:

• Added length constraints for todo title (max 100 characters)
• Added length constraints for todo description (max 500 characters)
• Implemented strict validation for title and description inputs
• Created static factory method for todo creation

Architectural Improvements:

• Consolidated multiple validation approaches
• Introduced companion object for todo creation
• Enhanced error handling with descriptive validation messages
• Standardized todo object initialization process

Core Modifications:

• Updated Todo data class with comprehensive validation
• Added priority enum for todo importance levels
• Implemented toggleCompletion() method for state management
• Added support for optional description and due dates

Tests and Verification

Test Coverage Enhancements:

• Added comprehensive test cases for todo creation
• Verified validation constraints for:
  • Title length
  • Description length
  • Completion status
  • Due date validity
• Implemented tests for edge cases and error scenarios
• Ensured factory method and constructor behave consistently
• Added script-based test runner for reliable verification

Verification Steps:

• Manually tested todo creation with various input scenarios
• Validated error handling for invalid inputs
• Confirmed preservation of existing functionality
• Reviewed test coverage to ensure comprehensive validation
