Non-functional testing is done to verify the non-functional requirement of the application like Performance, Usability, etc. It verifies if the behavior of the system is as per the requirement or not. It covers all the aspects which are not covered in functional testing.
At what level non functional requirement testing is performed?
Non-Functional testing is a software testing technique that verifies the attributes of the system such as memory leaks, performance or robustness of the system. Non-Functional testing is performed at all test levels .
How do you find non functional requirements?
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 testing is an example of non-functional testing?
Examples of non-functional testing types include security testing that validates the safety of customer information, performance testing that evaluates the application and processes under varied stressors, usability testing that assesses navigation and flow, or comparison testing that places your system up against its ...

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.
Who is responsible for non-functional requirements?
The architect might not be responsible for defining the non-functional requirements, but they're definitely responsible for fulfilling them. I agree, typically the architect will fulfil the requirements rather than define them, although sometimes you need to define them too.
What is functional testing example?
White box testing example: In this functional testing example, consider an end-to-end test for a customer who adds payment information to a retailer's app . Developers and testers would conduct tests in a white-box format to ensure that sensitive data, such as a credit card number, is stored in a PCI-compliant manner.

What is non-functional testing & its types?
Non-functional testing is a type of software testing to test non-functional parameters such as reliability, load test, performance and accountability of the software. The primary purpose of non-functional testing is to test the reading speed of the software system as per non-functional parameters.

What is the difference between functional and non-functional requirements?
While functional requirements define what the system does or must not do, non-functional requirements specify how the system should do it . ... Non-functional requirements define system behaviour, features, and general characteristics that affect the user experience.
