Nonfunctional Requirements Testing Questions

Approaches to validate nonfunctional quality attributes such as performance, reliability, scalability, security, and accessibility. Include designing load and stress tests, establishing baselines and detecting regressions, vulnerability scanning and penetration testing, accessibility audits and assistive technology verification, chaos and resilience experiments, and defining acceptance criteria for nonfunctional requirements. Candidates should discuss tooling, environment and data setup, reporting of results, and how to integrate nonfunctional checks into delivery pipelines and monitoring systems.
