Load Testing and Stress Testing

———- LOAD TESTING ————————-STRESS TESTING———–

Load Testing is performed to test the performance of the system or software application under extreme load.	Stress Testing is performed to test the robustness of the system or software application under extreme load.
In load testing load limit is the threshold of a break.	In stress testing load limit is above the threshold of a break.
In load testing, the performance of the software is tested under multiple number of users.	In stress testing, the performance is tested under varying data amounts.
Huge number of users.	Too much users and too much data.
Load testing is performed to find out the upper limit of the system or application.	Stress testing is performed to find the behavior of the system under pressure.
The factor tested during load testing is performance.	The factor tested during stress testing is robustness and stability.
Load testing determines the operating capacity of a system or application.	Stress testing ensures the system security.
