As you can see from that list, non-functional requirements are often referred to as "-ilities." How well non-functional requirements are defined and executed determines how easy the system is to use, and is used to judge system performance. However, four examples of Non-functional requirements we are discussing here are usability, reliability, performance, supportability, and scalability. The non-functional requirements are also called Quality attributes of the software under development. A usability requirement specifies how easy the system must be to use. While a system can still work if NFRs are not met, it may not meet user or stakeholder expectations, or the needs of the business. Non functional definition is the criteria that all product’s features should fall under. It verifies if the behavior of the system is as per the requirement or not. It is designed to test the readiness of a system as per nonfunctional parameters which are never addressed by functional testing. Non-functional requirements define system behaviour, features, and general characteristics that affect the user experience. The answer is usability. What is Non-Functional Testing? If you think of functional requirements as those that define what a system is supposed to do, non functional requirements (NFRs) define constraints which affect how the system should do it.. 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.

We also have security, performance, robustness and so on. Time of servers and other devices shall be synchronized to a reliable reference time. Now, let’s take a glance at popular platforms and apps to consider how their functional and non-functional requirements could be written. These are attributes that will help you define crucial user expectations and control product quality. Of course, not all non-functional requirements end in "-ility." 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. They describe how the system should work. Non-functional testing is done to verify the non-functional requirement of the application like Performance, Usability, etc. NON-FUNCTIONAL TESTING is defined as a type of Software testing to check non-functional aspects (performance, usability, reliability, etc) of a software application. 10 Examples for Non-Functional Requirements. Usability: Usability which means that how easy the software performs the specific task.in other words, it shows the ability of the software to perform tasks.
