NON-FUNCTIONAL TESTING is defined as a type of Software testing to check non-functional aspects (performance, usability, reliability, etc) of a software application. It is further divided into performance, security, usability, compatibility as the characteristics of the software. We also have security, performance, robustness and so on. Examples include reliability, availability, portability, scalability, usability, maintainability. The answer is usability. They describe how the system should work. Non-functional testing of Software involves testing the Software from the requirements which are non functional in nature related but important a well such as performance, security, user interface etc. A non-functional requirement is an qualitative requirement for a product, service, system, process, document, location, infrastructure component or facility. How well non-functional requirements are defined and executed determines how easy the system is to use, and is used to judge system performance. A usability requirement specifies how easy the system must be to use. Scalability: Processing throughput of batch jobs shall increase when adding CPU's; As you can see from that list, non-functional requirements are often referred to as "-ilities." Usability is a non-functional requirement, because in its essence it doesn't specify parts of the system functionality, only how that functionality is to be perceived by the user, for instance how easy it must be to learn and how efficient it must be for carrying out user tasks. Non-functional requirements define system behaviour, features, and general characteristics that affect the user experience. 10 Examples for Non-Functional Requirements.
