Stress Testing is primarily performed to evaluate which aspect of a system?

Stress testing is focused on evaluating a system's responsiveness under high-pressure conditions, which means it is designed to assess how the system behaves when subjected to extreme loads or stress. The objective of this type of testing is to determine the system's breaking point and identify any performance issues or failures that may arise when the system is pushed beyond its normal operational limits.

By analyzing how the system handles excessive demand, stress testing helps teams understand its scalability, robustness, and reliability in real-world scenarios where unexpected spikes in user activity could occur. This insight is crucial in ensuring that the application can maintain its performance levels and provide a seamless experience for users, even in challenging conditions.

While other types of testing focus on aspects such as stability, compatibility, or usability, stress testing is specifically concerned with measuring performance and responsiveness in situations that simulate high demand and can reveal weaknesses that might not be apparent under normal operating conditions.
