Non-Functional Testing
Testing qualities like performance, security, usability, and reliability rather than specific feature behavior.

What is Non-Functional Testing?
Non-functional testing evaluates how well a system works rather than what it does—covering performance, scalability, security, accessibility, reliability, and usability. A feature can be functionally perfect yet still fail users if it's slow, insecure, or inaccessible, which is why these qualities need explicit testing. Non-functional work spans load and latency testing, security and penetration testing, and accessibility checks. QI's bundled Strix pen-testing brings security into this picture, complementing the functional coverage produced by recorded flows.
