Comprehensive Update: Crypto Price Tracking and Validation Middleware

Description

Summary of Work

This pull request consolidates multiple improvements to our cryptocurrency price tracking and validation system, enhancing code quality, error handling, and middleware architecture.

Key Objectives:

• Implement robust input validation for cryptocurrency-related endpoints
• Standardize error handling and parameter checking
• Improve test coverage and middleware flexibility
• Enhance caching mechanisms for cryptocurrency data

The changes represent a significant step towards a more reliable and maintainable cryptocurrency information service, with a focus on clean, testable code and comprehensive validation.

Changes Made

Middleware Enhancements:

• Developed flexible input validation middleware for cryptocurrency endpoints
• Implemented comprehensive parameter checking for coin prices, lists, and details
• Added advanced validation with configurable format checks
• Created modular validation functions supporting multiple middleware strategies

Caching Improvements:

• Implemented a robust singleton CacheService with type-safe operations
• Added configurable cache creation with default and custom settings
• Enhanced test coverage for caching mechanisms
• Supported flexible cache configuration and management

Data Handling:

• Created standardized mock cryptocurrency price data structure
• Ensured consistent data representation across different endpoints
• Added support for various cryptocurrency metadata fields

Tests and Verification

Validation Middleware Test Coverage:

• Comprehensive test suite for input validation middleware
• Verified handling of valid and invalid parameter scenarios
• Tested edge cases for coin price, list, and detail validations

Caching Service Tests:

• Validated singleton instance creation
• Tested cache set, get, and delete operations
• Verified cache configuration and statistics retrieval

Mock Data Validation:

• Ensured mock cryptocurrency data meets expected structure
• Tested data integrity and consistency
• Verified numeric and metadata field representations

Overall Test Strategy:

• 100% coverage for new middleware components
• Rigorous validation of input processing
• Comprehensive error handling verification
