What is the difference between stress testing and endurance testing?

Stress testing and endurance testing are both types of performance testing, but they focus on different aspects of a system's performance.

Stress testing is conducted to evaluate the system's behavior under extreme conditions, such as high user loads, heavy data volumes, or limited resources. The goal is to identify the breaking point or the maximum capacity of the system and observe how it handles such stress. This type of testing helps uncover any performance bottlenecks, stability issues, or potential failures that may occur under stressful conditions.

On the other hand, endurance testing is performed to assess the system's ability to sustain a specific workload over an extended period. It aims to determine if the system can handle continuous usage without any degradation in performance or stability. Endurance testing helps identify any memory leaks, resource leaks, or other issues that may arise due to prolonged usage.

In summary, stress testing focuses on pushing the system to its limits to identify breaking points, while endurance testing evaluates the system's ability to sustain a workload over an extended period without performance degradation.
