Developed a comprehensive ABA Routing Number Validation Test Suite for the NCATComp410/comp410_spring_2025 repository, focusing on enhancing data validation processes for financial applications. Leveraging Python, test automation, and unit testing, the work centered on ensuring the analyze_text function accurately distinguishes valid routing numbers from invalid ones across multiple banks. The suite incorporated both positive and negative test cases, explicitly verifying the expected entity type to strengthen downstream data integrity. This targeted approach improved the reliability and quality of financial data validation, providing robust coverage for routing number scenarios and supporting maintainable, test-driven development practices within the project’s codebase.
