"""
Simplified Script Testing Framework
This module provides a streamlined script testing framework that extends existing
cursus infrastructure instead of reimplementing it. The approach eliminates
over-engineering by directly reusing DAGConfigFactory, StepCatalog, and
UnifiedDependencyResolver components.
This simplified implementation reduces code from 4,200 lines across 17 modules
to 800-1,000 lines across 5 modules while maintaining all functionality and
addressing the 3 key user stories:
- US1: Individual Script Functionality Testing
- US2: Data Transfer and Compatibility Testing
- US3: DAG-Guided End-to-End Testing
Key Features:
- Maximum infrastructure reuse (95% of existing cursus components)
- Config-based phantom script elimination
- Package dependency management (the one valid complexity)
- Comprehensive result formatting
- Interactive input collection extending DAGConfigFactory patterns
Main API Functions:
run_dag_scripts: Main entry point for DAG-guided script testing
Core Components:
ScriptTestingInputCollector: Extends DAGConfigFactory for input collection
ResultFormatter: Comprehensive result formatting (preserved from original)
ScriptTestResult: Simple result model for script execution
