What is the primary goal of non-functional testing?

The primary goal of non-functional testing is to assess system performance and usability. Non-functional testing focuses on evaluating aspects of the software that do not pertain to specific behaviors or functionalities. This includes performance metrics, such as response time, resource utilization, reliability, and overall user experience.

By examining these criteria, non-functional testing helps determine how well the application performs under various conditions, ensuring it meets user expectations and system requirements beyond just functional correctness. This is crucial for delivering a product that can handle the expected load and offers a positive experience to end-users, making it an essential facet of the software development and testing lifecycle.
