Which testing method focuses on ensuring that software works under expected workloads?

Stability Testing
Integration Testing
Performance Testing
Security Testing

The correct answer is: Performance Testing

Performance testing is a method focused on determining how a system performs in terms of responsiveness and stability under a particular workload. This type of testing assesses the speed, scalability, and reliability of the software application when it experiences different levels of user traffic or data processing. The purpose of performance testing is to ensure that the software can handle expected workloads effectively without degradation in performance, which is critical for maintaining user satisfaction and operational efficiency. Stability testing, while related to performance, is primarily concerned with the application's ability to operate effectively over an extended period. It evaluates whether the system can maintain performance levels without crashing or exhibiting erratic behavior. Integration testing focuses on assessing the interaction between different modules or systems to verify that they work together properly. Security testing is aimed at identifying vulnerabilities and ensuring that the software protects against threats; it does not primarily concern itself with performance under load. Therefore, performance testing is the correct choice when addressing the need to ensure that software functions properly under expected workloads.
