Regulatory Testing in Finance and Healthcare
Finance and healthcare are the two most heavily regulated industries for software quality. QA engineers working in these domains encounter regulatory requirements that go far beyond standard commercial software quality practices. Understanding the key regulations and their testing implications expands your career options into some of the highest-value QA markets.
Financial Software Regulations
- PCI DSS (Payment Card Industry Data Security Standard): Applies to any software handling payment card data. QA must test: encryption of cardholder data in transit and at rest, access controls to cardholder data environments, vulnerability scanning and penetration testing requirements, audit log completeness for all access to cardholder data
- SOX (Sarbanes-Oxley Act): US regulation for publicly traded companies - requires controls over financial reporting systems. QA testing requirements: change management controls (software changes must follow defined approval processes), access control testing (segregation of duties - the person who initiates transactions cannot also approve them), audit trail completeness for all financial data changes
- Basel III / Banking regulations: Risk management systems must demonstrate accuracy and reliability under extreme scenarios. QA testing includes stress testing of risk calculation engines, accuracy validation of financial models, and disaster recovery testing
Healthcare Software Regulations
FDA 21 CFR Part 11 (Electronic Records and Signatures): US FDA regulation for electronic records in medical devices and clinical systems. QA testing requirements: audit trail testing (system must log all electronic record changes with user, timestamp, and original/new value), electronic signature validation (system must enforce signature requirements and maintain signature integrity), access control testing (role-based access to patient data). IEC 62304 (Medical Device Software): International standard for medical device software development lifecycle. Requires: software safety classification (Class A/B/C based on patient risk), specific verification and validation evidence for each safety class, traceability from software requirements to design to verification evidence. HIPAA (Health Insurance Portability and Accountability Act): US healthcare privacy law. QA testing: PHI (Protected Health Information) access controls, audit logging of all PHI access, data encryption, and breach detection capabilities.

Tip
Tip
Practice Regulatory Testing in Finance and Healthcare in small, isolated examples before integrating into larger projects. Breaking concepts into small experiments builds genuine understanding faster than reading alone.
Practice Task
Note
Practice Task - (1) Write a working example of Regulatory Testing in Finance and Healthcare from scratch without looking at notes. (2) Modify it to handle an edge case (empty input, null value, or error state). (3) Share your solution in the Priygop community for feedback.
Quick Quiz
Common Mistake
Warning
A common mistake with Regulatory Testing in Finance and Healthcare is skipping edge case testing - empty inputs, null values, and unexpected data types. Always validate boundary conditions to write robust, production-ready qa engineering code.
