What is usability in non-functional requirements?
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.
What are the non-functional requirements in performance testing?
Nonfunctional Requirements (NFRs) define system attributes such as security, reliability, performance, maintainability, scalability, and usability. They serve as constraints or restrictions on the design of the system across the different backlogs.

Which is a non functional test?
Non-functional testing checks all the aspects not covered in functional tests. It includes the performance, usability, scalability, and reliability of the software. We conduct non-functional testing to make sure that the interests of the end-user are respected.

What are non functional requirements in SRS?
Non-functional requirements in an SRS document (software requirements specification) specify the quality attributes of a software system, such as responsiveness, usability, and reliability. As functional requirements indicate what a system must do, non-functional requirements support them and determine how the system must perform.
What is the difference between functional and non functional requirements?
As functional requirements indicate what a system must do, non-functional requirements support them and determine how the system must perform. These features are usually expressed as constraints or criteria that define a level of freedom for developers or users.
