Enhance Project Infrastructure: Testing, Modularization, and Dependency Management

Description

Summary of Work

This pull request consolidates multiple improvements to our project's core infrastructure, focusing on enhancing code quality, testability, and maintainability.

Project Evolution

We've undertaken a comprehensive refactoring to address technical debt and improve our development workflow. The changes span testing frameworks, dependency management, and service architecture, creating a more robust and scalable codebase.

Key Objectives

• Standardize testing infrastructure
• Improve code modularity
• Enhance dependency management
• Implement consistent error handling and validation
• Prepare for future scalability

Strategic Improvements

• Migrated from Vitest to Jest for consistent testing
• Implemented comprehensive module testing
• Refined project configuration for better dependency resolution
• Created more flexible, reusable service architectures
• Added robust error handling and input validation

Changes Made

1. Testing Infrastructure

   • Converted test suite to Jest framework
   • Updated test configurations in package.json
   • Implemented Babel for transpilation support

2. Service Architecture

   • Enhanced HeroDataService with more comprehensive methods
   • Improved type safety and method flexibility
   • Added additional querying capabilities (e.g., universe filtering)

3. Dependency Management

   • Updated package.json with explicit dependency configurations
   • Added Babel and Jest dev dependencies
   • Configured module transformation settings

4. Error Handling

   • Implemented more robust input validation
   • Added comprehensive error messages
   • Created consistent error throwing mechanisms

Tests and Verification

1. Testing Coverage

   • Added Jest configuration for comprehensive testing
   • Implemented tests for:
     • Crypto price data validation
     • Hero data service methods
     • Task funding mock functions

2. Test Improvements

   • Created flexible test cases supporting various scenarios
   • Added input validation test coverage
   • Verified mock function behaviors

3. Verification Steps

   • Ran full test suite to confirm zero regressions
   • Manually verified each test case
   • Ensured 100% pass rate across all test files
