What type of testing checks the software characteristics of a system?

Non-Functional Testing is focused on evaluating and verifying the attributes of a software application that are not related to specific behaviors or functions. Unlike functional testing, which assesses what the system does (i.e., its functionalities), non-functional testing concentrates on how well the system performs under certain conditions. This includes aspects such as performance, usability, reliability, security, and scalability.

By identifying issues related to these characteristics, non-functional testing ensures that the software not only meets the required functionalities but also adheres to quality standards in various contexts of use. This type of testing is essential to create a robust and user-friendly system that can handle real-world demands effectively.
