Description: Non-functional testing is a type of evaluation that focuses on how a system operates rather than what it does. These tests are crucial for determining the quality and performance of software, covering aspects such as usability, reliability, efficiency, scalability, and security. Unlike functional testing, which verifies whether specific software functions work correctly, non-functional testing examines the system’s behavior under various conditions and loads. This includes assessing response times, the ability to handle multiple users, and resilience to failures. Non-functional testing is essential to ensure that software not only meets functional requirements but also provides a satisfactory user experience and meets expected quality standards. In an agile development environment, these tests are integrated into the development lifecycle, allowing teams to identify and fix performance and usability issues before the software goes into production. In summary, non-functional testing is a vital component of modern software development, ensuring that systems are robust, efficient, and capable of meeting end-user expectations.
