What does system behavior testing verify?

System behavior testing is designed to verify that the system performs as expected under various conditions. This type of testing focuses on how the system behaves in terms of functionality, interfaces, and integration, as well as how it responds to different inputs and situations.

By conducting system behavior testing, testers ensure that all components work together as intended and that the system meets its specified requirements. This may involve examining how the system handles error conditions, manages load during peak times, or responds to standard operational tasks. Essentially, it assesses whether the system adheres to its design specifications and behaves reliably in real-world scenarios.

The other options, while related to aspects of product evaluation and performance, do not precisely capture the primary focus of system behavior testing.
